A bank will not give you a standard mortgage on a cooperative flat, because the flat belongs to the housing cooperative (bytové družstvo) and what you buy is only a cooperative share (družstevní podíl) that comes with the right to rent the flat.
The loan therefore has to be secured another way: with a charge on a different property (your own, or for example your parents'), with a short-term pre-mortgage loan (předhypoteční úvěr) that runs until the flat is transferred into personal ownership, or with a smaller unsecured loan from a building savings bank.
Legally, the share itself can be pledged (§ 32(3) of the Business Corporations Act), but in practice banks hardly ever offer it. The cheapest route is a charge on another property, because you pay a normal mortgage rate, on average 5.00 % in August 2026 (ČBA Hypomonitor). A pre-mortgage loan costs more, and you usually repay no principal while it runs. On a CZK 3,000,000 loan the difference over 18 months is more than CZK 70,000 in interest.
What you are actually buying
A cooperative flat belongs to the housing cooperative. You buy a cooperative share and, with it, the tenancy of a particular flat. When the share is transferred to you, the tenancy passes to you together with any debts the seller owed the cooperative (§ 736(2) of the Business Corporations Act).
The cooperative cannot block the transfer; you only have to meet the membership conditions in its articles (§ 736(1)). The transfer takes effect towards the cooperative on the day the contract is delivered to it (§ 601(2)).
For the bank this is a problem. The title deed extract (list vlastnictví) names the cooperative as owner, not the buyer, so no lien on the flat can be registered for you. The cooperative itself may pledge its flats only with the prior consent of at least two thirds of the members who rent them (§ 752).
How can you pay for a cooperative flat that cannot be pledged?
| Option | What secures the loan | Cost and limits | Suits whom |
|---|---|---|---|
| Mortgage secured on another property | your own flat, house or land, or your parents' property | normal mortgage rate; LTV is calculated from the value of the pledged property | anyone who has something to pledge |
| Pre-mortgage loan | unsecured for a time, then a lien on the flat once it passes into ownership | higher rate, usually interest only; the bank wants a written undertaking from the cooperative that the transfer will happen by an agreed date | cooperatives about to transfer their flats |
| Loan from a building savings bank | unsecured up to the savings bank's limit | limits in the hundreds of thousands of CZK, rate per the tariff | smaller sums, topping up the price |
| Pledge of the cooperative share | the pledge is entered in the commercial register (obchodní rejstřík) | the articles may rule it out; banks hardly use it | exceptional cases |
Not every bank offers all of these. Pre-mortgage loans for cooperative flats are available only from some of the larger banks, and their deadlines for the transfer differ. Ask precisely by when the transfer must happen and what follows if it is delayed.
With a pre-mortgage loan the bank may ask you for a promissory note. The law otherwise forbids them for consumer loans; the only exception is a housing loan that temporarily cannot be secured by a lien. Even then it must be a non-negotiable note, and the bank has to return it once the lien is registered (§ 112 of the Consumer Credit Act).
Pledge the parents' house, or take a pre-mortgage loan?
The Novaks buy a share for CZK 4,000,000 with CZK 1,000,000 of their own money and a loan of CZK 3,000,000. The cooperative promises to transfer the flats into ownership within 18 months. Their mortgage would run for 25 years at 5.00 %; for the pre-mortgage loan we assume a rate of 6.50 % and interest-only payments.
- Mortgage secured on the parents' house: a payment of CZK 17,538 from the first month. Over 18 months they pay CZK 221,716 in interest and the debt falls to CZK 2,906,037.
- Pre-mortgage loan: CZK 16,250 a month, interest only. Over 18 months they pay CZK 292,500 in interest and still owe CZK 3,000,000. After the transfer they switch to a mortgage at 5.00 % for the remaining 23.5 years, with a payment of CZK 18,105.
The pre-mortgage route costs CZK 70,784 more in interest, and the debt after the transfer is CZK 93,963 higher. Month by month it looks cheaper, because you are not repaying any principal. The 6.50 % rate is illustrative; the real one is in the bank's price list.
Pledging someone else's property has a price for the parents: if you stop paying, the bank can sell their house. How additional security works, and how to release the parents once the flat is transferred, is covered in Securing a mortgage with your parents' property.
What to check with the cooperative before you sign
- The commercial register extract and the articles. Who runs the cooperative, what the membership conditions are and whether the articles rule out pledging a share.
- The cooperative's confirmation that nothing is owed on the share. Debts to the cooperative pass to you with the share, and the seller remains liable for them even after the transfer (§ 601(1)).
- The cooperative's own loan on the building. How much is left to repay and what part falls on your flat; while the building is encumbered, a transfer into ownership tends to be harder.
- A resolution of the members' meeting or another written commitment to transfer the flats, if you are counting on it. With a pre-mortgage loan the bank will want to see it.
- The tenancy agreement for the flat and the monthly payments to the cooperative for rent, repairs and services.
The full list of papers for the bank is in Documents for a mortgage.
How does a transfer into personal ownership work?
It is not automatic. The cooperative signs a unit transfer agreement with you as its member and the tenant of the flat. It needs no consent from the other members for that: the law requires the consent of all member-tenants only when flats go to someone other than their tenants (§ 751 of the Business Corporations Act).
- The building must be divided into units by a declaration of ownership (prohlášení vlastníka) entered in the land registry (§ 1166 of the Civil Code).
- The cooperative approves the transfer and prepares the unit transfer agreement.
- You pay the part of the cooperative's loan that falls on your flat. For cooperatives founded before 1 January 1992, Act No. 311/2013 Coll. makes the transfer free of charge, and you pay only that share of the unpaid loan.
- The agreement goes to the land registry with an application to register your ownership; the administrative fee is CZK 2,000. No acquisition tax has been payable since 2020.
- If the building then has at least five units, at least four of them owned by different people, the owners must set up an owners' association (SVJ) (§ 1198 of the Civil Code).
Once the land registry records you as owner of the unit, the flat can be pledged. The pre-mortgage loan then turns into a standard mortgage, or you repay it with a new mortgage from another bank. A charge on the parents' house can be swapped for a charge on the flat. Either way you need a valuation, a new pledge agreement and a registration in the land registry costing CZK 2,000.
Interest on a loan to buy a cooperative share can be deducted from your tax base even before the transfer, provided you live in the flat. Paying for the transfer of a share counts as a housing need under § 4b of the Income Tax Act, and the same CZK 150,000 annual limit applies as for a mortgage.
A loan for a share is a housing loan even without a lien (§ 2(2) of the Consumer Credit Act). You therefore get 14 days to think it over before signing, and the same early repayment rules apply as for a mortgage.
