Czech Investment Mortgage Rules 2026: 30% Down on Rentals
From April 1, 2026 the Czech National Bank caps investment mortgages at 70% LTV and 7x net income on third homes and rentals. Here is what buyers should know.

Anyone in Prague who already owns a couple of flats and was planning to add a third just got a bigger bill at the bank. From April 1, 2026, the Czech National Bank applies tighter limits to mortgages taken out for investment, and the gap between buying to live in and buying to rent out is now written into the lending rules.
From April 1, 2026, an investment mortgage in Czechia is capped at 70 percent loan to value, meaning you need at least 30 percent of the price in your own funds, and total debt may not exceed seven times your net annual income. The limits apply to a third or further home and to any property bought to rent out. Loans for your own home are unchanged.
What exactly changes on April 1, 2026?
Two ceilings tighten for investment loans. According to the Czech National Bank (ČNB), the loan to value (LTV) limit for investment purposes drops to 70 percent, so a buyer needs 30 percent of the purchase price up front. At the same time the debt to income (DTI) cap is set at seven, meaning a borrower's total debt cannot exceed seven times net annual income. Both limits sit within the ČNB's macroprudential lending framework.
For a flat priced at 12 million Czech crowns, the 70 percent cap means roughly 3.6 million crowns of equity, well above the deposit a standard owner loan might require.
What counts as an investment mortgage?
The ČNB defines it by purpose. An investment mortgage is a loan to buy a third or further residential property, or a loan to buy any residential property intended for rental (pronájem). If either is true, the 70 percent LTV and the DTI of seven apply.
The tightening is a deliberate response to a hot market. The ČNB has described Czech housing as in the upward phase of its cycle, with prices climbing again after the 2023 dip, in its housing market assessment.
Who is not affected?
People buying their own home. Owner occupier mortgages keep their existing terms, including the more favourable treatment for young applicants under 36. If the flat you are buying is the one you will live in, the new investment limits do not apply to you.
What this means before you buy a rental flat in Prague
Plan the equity, not just the rent. If you are adding a rental flat or a third property, budget for 30 percent down and check that your existing debts leave room under the seven times income ceiling before you make an offer.
