Investment flat in Prague: how to choose one and calculate yield and costs

When choosing an investment flat, look beyond the kitchen and the view to the condition of the building, upcoming repairs and possible periods without a tenant. Judge the layout by how it works day to day, not just by the photos. Picture how the flat will function in five years’ time and get three things clear: who you want to let it to, how long you plan to hold it and how big a drop in income you can absorb. Then compare specific listings on that basis, including any roof repairs or work on other common parts.

Quick answer: an investment flat in Prague

Assess an investment flat by its total acquisition cost, a realistic rent and all future costs. In the model below, a 4% gross yield falls to roughly 2.6% before tax and financing once vacancies, management, owner’s costs and a reserve are taken into account. After factoring in the model mortgage, you end up topping up from your own pocket every month. With a different flat or a smaller loan, the result may differ.

From 1 April 2026, the Czech National Bank (CNB) recommends that banks apply an LTV of 70% and a DTI of 7 to investment mortgages. So what matters is not just how much of your own money you put in, but also the bank’s valuation of the collateral, your income and other debts. Before buying, check the legal status, the finances of the owners’ association (SVJ) and the repair plan. Choose the layout and form of ownership to suit your budget and investment plan, not according to a one-size-fits-all rule.

The 2026 market in numbers

Market data will help you get your bearings, but base any specific purchase on the price, rent and costs of that particular flat. The table lists market data and illustrative calculations separately:

According to this comparison, rents have grown faster than flat prices over the past five years, which can support rental yields. But comparing averages is not enough to decide on a specific purchase. In the 2026 table, mortgage rates are higher than the gross yields shown; whether you will have to top up the repayments also depends on the size of the loan, the rent and all your costs. In the model below you do need to top up, but with a different flat or financing the result may differ. Assess capital growth separately and allow for stagnation or a fall in value too. Prague’s average rent and average purchase price also cover different types of flats. For your own listing, compare units of similar age, condition and location.

Rental yield is not a single number

When a listing quotes a yield, check what it includes. The gross percentage may be calculated correctly but leave out management, vacancies and repairs. For your own budget, you therefore need the figure after these costs too.

Repaying the mortgage principal reduces both your cash and your debt. It is not the same kind of cost as interest, but you still need the money for your monthly budget. Rising market prices, on the other hand, may increase the value of your asset, but they won’t pay today’s plumber’s bill and aren’t guaranteed. Keep these things separate. Otherwise the investment may be profitable on paper while your bank account runs short.

Model: from a 4% gross yield to a monthly budget

A 2+kk flat, 52 m², in an older building near the metro, with a total upfront investment of 7,500,000 Kč including commission, legal fees and basic preparation (real estate acquisition tax has not been payable since 2020). Rent of 25,000 Kč per month excluding utilities. Gross yield: 300,000 / 7,500,000 = 4.0%.

Now for the financing. At an LTV of 70% of a bank valuation of 7,000,000 Kč, the mortgage comes to 4,900,000 Kč. At a model rate of 5.5% over 30 years, the annuity payment works out, rounded, at approximately 27,800 Kč a month, or 333,600 Kč a year. Cash flow with the rounded payment: 194,755 − 333,600 = −138,845 Kč a year, i.e. roughly 11,600 Kč a month out of your own pocket. The calculation does not include income tax or any other loan fees.

Part of the payment pays down the principal, so the annual top-up is not the same as an accounting or economic loss. At the same time, it is not money you can spend again. The reserve in the table is set aside for future expenses, and you may not need all of it in a given year. Calculate any capital growth from the market value of the property, not automatically from all acquisition costs including commissions. Alongside growth, test a scenario where the price stagnates or falls.

The model is neither a forecast nor an offer from FLAT SERVICE. It shows a structure into which you can plug your own numbers. In this particular scenario, you need not only the money to buy but also funds for ongoing top-ups. With a different ratio of price, rent and loan, the cash flow may be positive. Nor does a long investment horizon on its own guarantee that the purchase will pay off.

Location: follow your future tenant’s typical day

The name of the district is not enough. Walk the actual route to the metro or tram, check the shopping options and visit the area at different times of day. A flat on a main road and one facing a quiet courtyard can share an address yet attract very different demand.

According to Deloitte, the gap between the most expensive district in the comparison (Prague 7, 493 Kč/m²) and the cheapest (Prague 10, 442 Kč/m²) is roughly 12%. Purchase prices vary more in the published surveys: new flats in Prague 2 cost around 265,000 Kč/m², in Prague 10 around 159,000 Kč/m² (Deloitte, Trigema). A lower purchase price on the outskirts can be an opportunity for a higher yield, but you need to verify the achievable rent and occupancy too. In the centre, likewise weigh up price, demand and resale potential; the address alone guarantees neither that value will hold nor that the flat will let quickly. Compare listings within the same segment: you can’t set the rent of an older flat against the purchase price of a premium new build. For each location, prepare both a realistic and a cautious rent scenario.

Think about who the location will suit. For a single person commuting to an office, transport and amenities may matter most; for a family, also nurseries, layout and storage space. Check planned construction too: if a thousand similar flats are going up nearby, tenants will have a bigger supply to choose from. For future transport projects, such as metro line D or new tram lines, go by the actual stage of planning or construction, not just the expected date in a sales brochure. You’ll find detailed reference rents for each cadastral area in our location overview.

Layout and furnishings: the square metres must be usable

In Prague, single-person households make up 43% of all households (Czech Statistical Office, 2025). In new rental projects, 1+kk and 2+kk units account for 80% of the housing stock, and the average floor area has fallen to 49 m² (Association for Rental Housing). These figures can help you choose a target group, but they don’t on their own determine the most profitable or most easily sellable flat. For a 2+kk of 45 to 55 m², consider whether the layout will suit a couple or a single person needing a study, and whether the total monthly payment is affordable for your intended tenant, for example someone on a single income. According to UlovDomov, 2+kk flats saw the biggest year-on-year rent increase (+14%), while 3+kk flats got cheaper (-5%). For a specific flat of around 50 m², still check for a separate bedroom and space for a desk; statistics are no substitute for assessing the floor plan.

For small flats, compare both the higher rent per square metre and the purchase price: UlovDomov puts rent for 1+kk at around 530 Kč/m², while Deloitte reports purchase prices for new 1+kk units of over 200,000 Kč/m². Larger flats may command lower rent per square metre, but the overall yield also depends on other costs. Don’t infer the length of tenancies or tenant turnover from the layout alone. For both small and large flats, budget for re-letting and its costs.

A floor plan reveals more than a wide-angle photo. A large hallway is no substitute for living space. Look at where the doors are, whether standard furniture will fit, the light and the storage. Choose furnishings to suit your target tenant: a functional kitchen and good lighting play a different role from a fully furnished flat. Every item of furniture means future replacement, and your yield model should account for it. For a flat that needs renovating, get an itemised budget, a timeline and a contingency before making a binding decision. A generic price per square metre is not enough. More in our article on renovating a flat before letting it.

Check the building, SVJ and legal status

Check the condition of the whole building, even if the flat itself has a new bathroom. Along with the unit, you acquire a share in the common parts and make decisions on building management together with the other owners. Planned repairs to the roof or other parts may feed through into your costs. Before signing a reservation agreement, ask for:

1. Land registry extract (title deed): owner, liens, easements, enforcement orders, notes of disputes.
2. The SVJ’s articles of association, minutes of the last two general meetings and its financial statements. Look for planned repairs (roof, lift, façade, risers), the size of the repair fund and owners’ debts to the SVJ.
3. Confirmation from the person responsible for building management of any debts owed by the seller (§ 1186(3) of the Civil Code). Under specified conditions, the law allows debts for building management contributions, services and advances to pass to a buyer who knew or could have found out about them. So not every unknown debt passes over automatically. Have the confirmation reviewed together with the purchase agreement and the settlement arrangements.
4. Registration sheet and breakdown of advances. You’ll find out how much the tenant will pay in total, which affects the rent you can achieve.
5. The building’s energy performance certificate (PENB) and information on insulation: it determines heating advances and your obligations when letting (§ 7a of Act No. 406/2000 Coll.).
6. Declaration of ownership: what exactly the unit consists of, what counts as a common part, and whether the “cellar” in the listing really belongs to the unit.

Marketing labels such as “apartment” or “studio” don’t in themselves say what use the space is approved for. Check the building documentation, the legal status and the bank’s conditions. The reverse also applies: under § 2236 of the Civil Code, tenant protection cannot be circumvented simply by calling a space non-residential if the parties agreed it would be lived in. Whether residential use is permitted under building law and the tenant’s private-law protection are two separate questions. A lower price may be no bargain if they are unresolved.

Investment mortgages in 2026: your own money is not the only requirement

From 1 April 2026, the CNB recommends that banks apply limits of LTV 70% and DTI 7 to investment mortgages. These cover loans for residential property intended for letting, or for an applicant’s third or subsequent residential property. They are recommendations to lenders, not an applicant’s entitlement to a loan; banks may set stricter conditions.

LTV compares the loan with the value of the collateral according to the bank’s valuation, not your purchase price. With a valuation of 7,000,000 Kč, 70% is 4,900,000 Kč. If you are buying for 7,300,000 Kč and need 200,000 Kč for preparation, you must have 2,600,000 Kč of your own funds plus an operating reserve.

DTI relates the applicant’s total debt, including other loans, to their net annual income. With a debt of 4,900,000 Kč, a DTI of 7 corresponds to an annual income of 700,000 Kč, i.e. approximately 58,333 Kč a month, if you have no other debts. This is only one of the tests, not a promise of approval. Whether the bank will take future rent into account, how much of it and on what supporting documents depends on its own rules. Check this before signing a reservation.

According to the Swiss Life Hypoindex, the average advertised rate in September 2026 was 5.51% and had risen for the sixth month in a row. ČBA Hypomonitor reported 4.90% for new loans actually agreed in July. These cover different periods and different sets of loans, so the difference doesn’t tell you what discount a client negotiated. Compare specific offers for the same loan, including the APR, insurance, fees and early repayment terms. Match the length of the fixed-rate period to your plans and your ability to cope with a higher payment once it ends.

Buying a flat with a sitting tenant: check the agreement and payments

With a flat that is already let, you can verify the actual rent, the payment history, the term of the agreement and how service charges are allocated. That reduces uncertainty compared with an empty flat, where all you have are the seller’s expectations.

At the same time, you are buying an existing tenancy. A change of owner does not end the tenancy, and the buyer steps into the landlord’s rights and obligations (§ 2221 of the Civil Code). The purchase itself is not grounds for terminating a residential tenancy. Special rules apply to arrangements imposing obligations on the landlord beyond the law that the new owner did not know about (§ 2221(2)). So ask for the agreement before signing and have it reviewed as a whole. Rent can be changed by agreement, under a valid contractual mechanism or, where the conditions are met, through the statutory procedure. You don’t always have to wait for the agreement to be renewed.

Ask for the agreement with all amendments, documents relating to the security deposit, the current registration sheet and the latest service charge statement. Under § 2221 of the Civil Code, the landlord’s rights and obligations pass to you, including those relating to the security deposit. So deal with its transfer from the seller as part of settling the purchase price. A long-term tenant with a spotless payment record can be an advantage, provided you know the terms of the continuing tenancy. We cover taking over management during a tenancy in more detail in our article property management versus an estate agency.

Private individual or s.r.o.?

Decide on the form of ownership before you buy. A later transfer can bring additional costs and tax consequences. The number of flats alone doesn’t give you the right answer. It also depends on co-investors, financing, how you draw profits and your plans for selling:

For one to three flats held long term, compare taxation as an individual, the option of the flat-rate deduction, the conditions for exempting a sale after the holding test, and the specific financing offer. Also consider an s.r.o. if you are reinvesting profits rather than paying them out to the owners, if several co-investors are involved, or if you run short-term accommodation services. Even a portfolio of more than five flats does not in itself mean that company ownership and accounting will pay off. What counts is the overall calculation. A tax adviser should compare the same flat, the same expenses and the same horizon under both regimes. In the model above, the 10.5% is calculated from income and the 32.85% from profit; the rates can’t be compared directly without these assumptions. More detail in our guide to rental income tax.

Test three less favourable scenarios before you buy

What if the flat stays empty for three months? With rent of 25,000 Kč, you lose 75,000 Kč of income while the mortgage payment, SVJ contributions and energy keep running. Do you have a reserve covering at least six months of payments?

What if an expensive appliance or a common part of the building needs repairing? Test, for example, an unplanned expense of 40,000 Kč in the flat or a 150,000 Kč contribution towards repairing the building. These are stress scenarios, not a price list. Base your actual reserve on the condition of the flat and the SVJ’s plans. It shouldn’t exist only in the value of a property you don’t want to sell.

What if I need the money sooner? Finding a buyer is not the same as having the purchase price in your account. Allow for due diligence, the buyer’s financing, contracts and the land registry. Sale speed and costs vary, and an urgent deadline can weaken your negotiating position. You can’t always sell a flat quickly at your asking price.

These questions won’t guarantee your investment succeeds, but they will show whether your plan can withstand a less favourable year. If the reserve doesn’t add up, adjust your budget, the loan amount or your choice of flat before you reserve.

FAQ

Is it worth buying an investment flat in Prague in 2026?

It depends on the specific purchase price, rent, costs and financing. Neither paying cash nor taking a small loan guarantees a good return on its own. If you are counting on a yield of 2.5 to 3% after costs and a horizon of ten years or more, verify these assumptions and also run a scenario with no capital growth. In this article’s model, an LTV of 70% leads to a monthly top-up; with a different price, rent or loan, the result may differ. For a regional listing with an expected gross yield of 5 to 7%, check demand, possible vacancies and resale prospects as well as the yield. Treat yield ranges as a guide for comparison, not a promise of results.

Is a small flat always the best investment?

No. A higher purchase price can outweigh the higher rent per square metre. Compare the overall financial result, how usable the floor plan is and demand in the specific location. A 1+kk or 2+kk label alone doesn’t guarantee a better investment.

Can I rely on the yield quoted by the seller?

Treat it as a figure to be verified. Find out whether it is based on an actual agreement or an estimate, which costs the calculation leaves out and as of what date it applies. Compare it with the reference rent for the cadastral area in our location overview.

New build or older flat?

Compare the price and future running costs of specific flats. The guide figures above work with new flats at around 183,000 Kč/m² and older ones at around 160,000 Kč/m². With a new build, check whether the higher purchase price is offset by fewer initial repairs, lower service advances and tenant interest. With an older flat, assess the achievable yield, the location and the condition of the building and its wiring and plumbing. A better price may be cancelled out by necessary repairs. Nor does a new flat mean ten years without costs: there may be defect claims or unfinished surroundings. And an older flat doesn’t automatically deliver a higher yield. Decide based on the total investment, including preparation for letting.

Can property management start straight after the purchase?

Yes, you can prepare for management while still choosing the flat. With an existing tenancy, we pick up the valid agreement and take over the documentation; with an empty flat, we prepare the listing and handle the letting. When we search for an investment flat, we assess it from the outset with future letting in mind.
