About Casum
What is Casum?
Casum is a new way to buy your house, which allows you to gradually buy your house while paying rent for the part you haven’t yet bought.
Who is Casum?
Casum is a company created by Nuclio, a company that specializes in launching digital companies.
In addition to Casum, Nuclio has promoted other successful companies in the real estate sector such as Housfy, Finteca, Pro Hipotecas and Eelp.
The Casum management team has extensive experience in both the digital and real estate sectors, especially in residential rentals.
Is Casum a mortgage?
No, Casum doesn’t make you incur debt, like a mortgage. With Casum you have the option of buying a part of your house little by little, but you don’t have to, which is why you can choose a plan to buy more of it without having to borrow money.
Who does Casum focus on?
Casum seeks to facilitate access to housing for those who haven’t been able to save the initial amount required to access a mortgage, but who have payment capacity.
To access a mortgage, one needs to save up to 30% of the house’s value. This leads to a large number of people taking years to save the money required to buy, while they are forced to rent.
At Casum, we understand that there’s an unmet need in the market to allow people living on rent to make a gradual transition from the rental market to the property market.
With our flexible plan, we help these people, so they can initially buy the part of the house that they can afford with their current savings, and then gradually buy more of the house, without having to borrow, until they meet the mortgage’s conditions.
How can I get more information about Casum
At Casum we’ve created an exhaustive frequently asked questions section, which we update based on the new questions we receive.
We advise you to check out this section, but if you can’t find what you’re looking for or still have doubts, you can send us your questions at info@casum.com
Also, during the house application and purchase process, we’ll contact you directly, so you can also ask our team during the process.
If you want to see examples of how Casum works, you can see them in Casum’s search engine.
How is Casum different from the traditional rental?
The main difference concerning traditional rental is that with Casum you can gradually buy part of the house.
By owning part of your property, you don’t have to pay a monthly rent for that part. Therefore, your monthly rent will always be lower than what you’d have to pay if you rented the entire house.
How much does Casum cost?
Casum will be with you throughout the entire process, from the initial sale until you decide to buy the entire house (or decide to leave it).
When the house is purchased, Casum will charge you a management fee. This feel will depend on the type and complexity of the operation. During the application process, we will send you a customized proposal specifying the amount of these fees.
About our investors
Who buys the house with me?
![CDATA[Casum has a network of investors seeking to invest in real estate. One of them will buy the house with you.
Our investors are mainly investment funds and family offices looking for a long-term relationship, so their interests align with yours.
The conditions will also be contractually regulated to give you peace of mind.
How many investors will buy with me?
There is only one investor per house. That way, we can ensure that when we need the investor's decision in some aspect, the process is as agile as possible.
Will I have to deal directly with the investor?
No. Casum will be by your side throughout the entire process and will ensure that what’s contractually regulated is fulfilled.
If the investor’s decision is required (for example, if the boiler needs to be changed), Casum will manage it.
Application process
What do I have to do to apply to Casum?
First, you’ll have to register online in our system and complete some questions, which will allow us to understand your case a bit better and assess whether Casum can help you.
To start the registration, you can follow this link SIGN UP
Do I need to meet any minimum requirements?
To move forward in the application process, you need to meet the following requirements:
  • Have enough money saved to initially buy at least 5% of the house.
  • Have a joint annual gross salary of more than € 25.000/year (either if you buy it alone or with someone).
  • Not have any previously unpaid debt.
What documentation will I have to provide?
Before we start looking for a home we’ll have to confirm that you have the minimum initial deposit necessary to buy a part of the house (5%, with a minimum of € 10.000) and that you can pay the rent.
To do this, we’ll ask for information about your income and debts. The information we’ll request will be similar to what a landlord would ask for when renting a home.
How does the process continue once my payment capacity is validated?
Once your payment capacity is validated we’ll let you know if Casum can help you.
If we consider that Casum can help, we’ll send you a qualification report telling you the budget you can aim for to buy a home.
This information will allow you to focus your search better, so you can show us the homes you’d like and which are within the budget.
Home purchase
Can I choose my home or should I choose from among certain homes?
You can choose the home that you’d like and that is within the budget that we’ve indicated during the application process, in Casum’s search engine you can also find different examples of properties.
Once you present a proposal, we’ll analyze it to validate whether we also like it, and if we do, we’ll send you the monthly rent calculation that you’ll have to pay every month to the investor, for his part. The rent will be calculated based on the area’s market rental for a house with similar characteristics.
What type of housing can I buy? Are there any limitations?
Even though we’re open to assessing different options, the type of house in which we’d be most interested would have the following characteristics:
  • With a price of up to € 300.000
  • Over 50 m2
  • With 2 or 3 rooms
At Casum, we aren’t interested in the following type of housing:
  • Officially protected housing (VPO).
  • Self-promotion housing
  • Rustic properties
  • Plots of land
  • Housing with charges or rights that cannot be undone at the time of sale
  • Housing with serious structural problems or that require significant repair and/or maintenance costs.
We’re currently focusing on second-hand homes instead of new homes. The reason is that second-hand homes are easier to appraise, since there are usually references to similar transactions within the same building or in the area. In case of new housing, valuation is more difficult due to a lack of similar reference properties on which to base the estimated price, and because they’re usually located in development areas that tend to have a more volatile price evolution.
In which cities/areas should you buy?
We are currently focused on homes located in Madrid, Barcelona, Zaragoza and Valencia. However, we are open to other locations depending on the operation.
What’s the minimum deposit I should invest at the beginning? And the maximum?
The minimum deposit required is 5% of the cost of the property. However, it will be easier for us to get an investor if your contribution, in addition to being more than €10,000, allows you to cover at least the purchasing costs.
What is my deposit for?
The deposit allows you to own part of the home from the very first day, you’ll save on rent for that part of the house.
Can I lose my deposit?
No, as long as you pay the agreed rent. However, if you make any default or leave before the minimum permanence period, your deposit will be used as collateral to collect the debts you generate or to compensate investor’s initial costs in case you leave the house before the permanence period.
You should also bear in mind that if after the permanence period you decide not to buy the house and it needs to be sold, the amount of the deposit that you’ll get back will depend on the final price at which the house is sold. So, the value of your deposit can increase if the house has been revalued or decrease if the house has depreciated.
When the home is initially purchased, how are the costs associated with the purchase distributed?
In addition to the house’s purchase price, a series of expenses are incurred during the home’s purchase: physical appraisal, real estate commission (if it isn’t already included in the price), notary, agency, taxes, property registration, etc.
Expenses that are directly attributable to one of the parties will be paid by that party and the joint costs (not attributable to one of the parties) will be paid pro rata between the parties; that is, each of the parties will pay the percentage of said costs equivalent to the home percentage acquired.
Do you make a physical appraisal of the house?
At Casum we analyze various aspects to ensure that the house has an adequate price in comparison to other homes in the same area and is in good condition so you can live in it.
Therefore, an important part is the physical appraisal of the house, which we’ll carry out at the end of the process, before buying the house. The home’s physical appraisal will be carried out by an independent third party who specializes in this type of appraisals.
Who pays appraisal costs?
The cost of an appraisal can vary and will depend on the area and the type of housing.
During the physical appraisal, you’ll pay the costs pro rata with the investor, so you’ll have to cover the proportion based on the percentage of the home you are buying with your initial contribution. So, if the appraisal costs € 400 and you’re initially buying 5% of the home, you’ll have to pay € 20 for the appraisal.
Keep in mind that you’ll have to pay your share of the appraisal, even if the property isn’t finally purchased. In any case, we understand that it’s always better to assume a small cost to assess the house physically, than to buy a house at an excessive price or with a problem that could lead to higher costs in the future.
Will Casum negotiate the property price with the seller?
Casum seeks to obtain a purchase price that is as attractive as possible for both you and the investor. Therefore, Casum will negotiate with the seller to obtain the lowest possible price.
If a lower price than the starting price is acquired, you’ll benefit from it because you can buy a higher percentage with your initial deposit and because you can make partial repurchases of the house at a lower price by having a lower starting price.
Do I have to sign a contract?
Yes. Before buying the home, you must sign a contract with the investor that stipulates each of the parties’ rights and obligations.
What is the duration of the contract?
The contract can last up to 10 years. You can choose the duration that best suits your needs and saving capacity, so you can meet the conditions to buy the home (either with your money or through a mortgage).
Can I extend the duration of the contract?
To extend it, you’ll also need the investor’s consent. Each case will be different, so if you want to extend the duration once you’re already in the house, we advise you to contact us promptly to see if we can manage it.
Home rental
How is the monthly rental income calculated?
The monthly rent to be paid to the investor is calculated based on the market rental price of the area where the home is located.
To calculate it we rely on reports and independent agencies’ indices.
Once we’ve estimated a market price for your home’s rental, we subtract the rent from the percentage of the home that you own; the rent you pay will always be less than the rent you’d pay if you had to rent the entire house.
For example, if the housing market rental price is € 1.000 per month and you bought 10% of the house and the investor the remaining 90%, you’ll have to pay a monthly rent of € 900 (90% of € 1.000), so you’ll save € 100 per month (€ 1.200 per year).
Thus, as you buy more of the property, you’ll save more, which you can reuse to buy more of the house.
Can the monthly rent vary?
Yes, the variation in the monthly rental can be due to two reasons:
  1. If you buy part of the home from the investor, you will stop paying rent for the part you have bought, so your monthly rent will decrease.
  2. As in traditional rentals, the rent for the part you have to pay to the investor will be adjusted once a year according to the variation of the CPI.
What happens if I can’t pay my monthly rent?
Before that happens, the best thing you can do is let us know so we can jointly assess your options before it’s too late.
For our part, we’ll treat each case individually and look for a case-based solution with the investor.
Keep in mind, that the non-payment of your monthly rent can lead to the loss of the purchase option and to having to resort to the part of the house that you purchased as consideration for the defaults you made and the associated costs in case the house needs to be sold.
Can I make changes to the house?
This is your home, so you can make any changes you want and decorate it to your liking. However, for major reforms, since they can affect the value of the home, you’ll need prior approval.
Who will pay the costs associated with the property such as community fees and IBI?
When calculating the rental price of the property, Casum deducts from this initial estimate the average cost of ownership for a property. In this way, the rental price that we will indicate to you is reduced by the property costs that you will have to pay (unless there is an overrun that will be paid pro rata according to the percentage of ownership of each one of you). By doing it this way, we do not limit your search for a property and you will be able to choose one with high community costs (for example, properties with a concierge, swimming pool and communal areas), but you will have to assume the difference between the average property expenses that we have deducted when calculating the rent and the real cost of the property expenses of that property.
Gradual purchase of a larger part of the house
How can I increase the percentage of the house that I own during the duration of the contract?
You can decide to buy a larger part of the house at any time, with no minimum repurchase commitment. There are two ways to increase the percentage of the house that you own:
  • Establishing a periodic repurchase fee. This is the most advisable option to gradually increase the percentage that you own. You decide the fee, so you can vary it based on your needs and even eliminate it if you need to allocate money to other issues.
  • Punctual repurchase. If you have some extra income (an extra payment, an inheritance, etc.) you can allocate it directly to buy more of the house as a one-off contribution.
At what price can I do a partial purchase?
The price at which you can buy back more of the property is variable and corresponds to the initial purchase cost plus the average variation of the prices of the properties in the area.
  • For example, if a home is had a cost of € 200.000 and the homes in the area have increased by 2% in price, the price at which you can buy more of the home at that time will be € 204.000
Casum obtains the price variation for homes in the area based on reports and indices from independent agencies. Casum will regularly update the housing market price and inform you, so you can take it into account for your repayment plan.
In the event of price drops, a Minimum Price equivalent to the initial cost of the property will apply. In this way, the Investor is assured that he recovers the investment made, since he is contractually obliged to sell to you and only you are the one who decides when to buy and at what rate to do so.
Why isn’t it a fixed price?
If we establish a fixed repurchase price, not really knowing the evolution of future prices, the investor could demand higher repurchase prices than expected to cover any risks.
In addition, by establishing a fixed repurchase price, you’d have to buy the house while paying the home’s future estimated price from the beginning.
Can I register the new purchases made of the house in the property register?
Of course. You only need to request it and we’ll do everything so that the part of the house you purchased is updated in the property register.
Bear in mind that you’ll have to cover the costs of registering the part of the property that isn’t yet registered.
In any case, even if partial purchases of the home aren’t registered in the property register, they’ll be reflected in a private document; therefore, you will be able to prove at all times the part of the property that you have purchased.
Purchasing 100% of the house
When can I buy 100% of the house?
With Casum, if at any moment your financial situation improves or you have access to a mortgage, you have the possibility to buy to the investor the whole house instead of waiting until the rent agreement expires.
Therefore, you can buy 100% of the house at any time.
At what price can I buy 100% of the house?
The price at which you can buy 100% of the house is similar to the price when you make partial purchases. It is a variable price and corresponds to the initial cost updated to the moment you buy 100% of the house . To calculate the price of the house, the initial purchase cost (including purchase costs) plus the average variation of the prices of the houses in the area.

  • For example, if a house was bought for 200,000 euros and the houses in the area have increased their price by 5%, the price at which you can buy 100% of the house at that time will be 210,000 euros

Casum obtains the variation in the price of the house in the area based on reports and indices from independent bodies.
In the event of price drops, a Minimum Price equivalent to the initial cost of the property will apply. In this way, the Investor is assured that he recovers the investment made, since he is contractually obliged to sell to you and only you are the one who decides when to buy and at what rate to do so.
Will Casum help me get a mortgage?
Of course. Casum's goal is to accompany you throughout the process, making life easier and aiding you with paperwork. As soon as you meet the conditions to access a mortgage, Casum will help you manage the application with various banks.
When I buy the entire house, what purchase costs should I cover?
As a buyer of the entire home, you must bear the costs of the entire process (physical appraisal, notary, agency, registration in the property registry and mortgage expenses in case of mortgaging) as well as all buyer-attributable taxes.
Can I leave the house early?
The investor who bought the house with you trusted you when they invested, so they’ll require a minimum permanence period.
Is there a penalty if I leave the house before the contract ends?
If you leave the house before the contract expires, the investor won’t have had time to amortize the purchase expenses he assumed at the time of purchase (registration, agency, notary, taxes, etc.).
Therefore, to ensure that the investor isn’t harmed, if you decide to leave the house before the contract expires, you must pay penalties to cover the expenses that the investor incurred and which haven’t been amortized to that date.
What happens if I want to leave the home after the permanence term?
Casum focuses on customers who want to buy a home and our goal is to help you get 100% of it. However, you’re not obliged to buy it. Therefore, once the contract is completed, you’ll be able to leave the house.
To leave the house you must follow this process:

  • Tell us that you want to leave the house.

  • We will contact the investor, so he can assess if he is interested in buying you your part of the house. The investor will have two months to decide if he is interested in buying the house and in case he is interested, he will have 3 extra months to execute the purchase.

  • In the event that he decides to sell his share together with you, then the sale costs will be shared pro rata, depending on the percentage that each party has.

  • Once the property is sold, you will be able to stop paying rent and you will receive the amount of the sale in proportion to your percentage.

If I leave the house at the end of the contract, will I recover some of the money invested?
Yes of course. As you own a percentage of the home, you’ll receive the amount of the sale proportional to your percentage.
Therefore, if the house is revalued you can receive more money from your contribution. And vice versa, if the price of housing has devalued, you’ll recover less money than what you invested.
