How to value your Prague flat before selling
A flat is worth what a real buyer will pay, not what the neighbour got or the portal suggests. Four methods get you close, and each has a blind spot.

The first number a seller picks is often the one that sticks, and it is usually picked for the wrong reasons: a friend's sale, an advert in the same street, or a figure that would make the next purchase easier. The market does not care about any of that. Buyers compare your flat with the others they can see, and a flat that is priced above them waits.
Valuation is therefore the first practical task of a sale. This guide describes the methods available in Prague, what each can and cannot tell you, and how to combine them into a price you can defend.
Three different numbers
Before the methods, a distinction that saves confusion. Three kinds of figure are in circulation.
- An asking price is what other sellers hope to get. It is a ceiling, not a result.
- A transaction price is what a buyer and seller agreed. It is the best evidence of value, but it is harder to find.
- A valuation is a professional opinion, prepared for a particular purpose such as a mortgage, an inheritance or a sale.
Our explainer on apartment prices by district shows why these should not be compared directly.
Method one: comparable sales
The oldest method is still the best. Find flats similar to yours, in the same building or on the same few streets, and note what they sold for and when. Adjust for size, floor, lift, balcony, condition, building quality and the owners' association's finances.
Sources include adverts that have been removed (a sign of a sale, though not of its price), the knowledge of a local broker, and the registered contracts in the cadastre. Access to registered deeds is governed by the cadastre's rules, so check ČÚZK for what you can see and how (as of 2026; check ČÚZK).
The blind spot is the sample. Three comparables are better than none, but they may all have sold in a different market from today's. Use the latest data you can find, and check it against the price index published by the Czech Statistical Office to see how the market has moved since.
Method two: a broker's estimate
Most brokers will give a market estimate without charge, in the hope of winning the listing. A good one explains the comparables, the likely time on the market and the price at which the flat would sell quickly. A less good one names a high number to win your signature and cuts it later.
Ask two or three brokers independently and ask each to show the evidence. If one estimate is far above the others, ask why. Our guide to real estate agents and fees covers the commission questions that go with this.
Method three: online estimates
Online tools give an instant range based on the address, size and condition you enter. They are useful for a first indication and they cost nothing. The valuation service at odhad.homerealestate.cz (in Czech) is one such tool. Treat the result as a starting range, not a verdict, because an algorithm cannot see the view, the state of the staircase or the minutes of the last owners' meeting.
You can also run the numbers on what remains after costs and tax with the property sale calculator on Hypoteky.com. That is a model for your own planning, not a valuation.
Method four: a formal appraisal
A formal valuation (znalecký posudek or ocenění) is prepared by a sworn expert listed by the Ministry of Justice, or by an appraiser working for a bank. It follows a defined method, includes a report and can be used in a dispute, an inheritance or a loan application. It costs money, and it takes time.
For a standard sale it is often not necessary. It is worth considering in special cases:
- The flat is unusual: a loft, a mansard, an attic conversion, a unit with a large terrace.
- Several co-owners disagree about the price.
- The sale follows an inheritance or divorce, where a documented value helps.
- The buyer's bank requires its own valuation and you want to anticipate it.
A bank's valuation, ordered by the buyer's lender, can come out below the agreed price. In that case the loan covers a smaller share and the buyer must find the difference or renegotiate. It is worth knowing how it works before you set an ambitious price. Our piece on how much deposit a Czech mortgage needs explains the loan-to-value framework from the buyer's side.
What moves the value of your flat
Some factors are obvious, such as location, size and condition. Others are easy to overlook until a buyer raises them.
- The building. Reserve fund, planned repairs and any loan taken by the owners' association.
- Legal cleanliness. A clear title, no pending enforcement notes, correct unit description. Read our guide to the Czech property extract.
- Energy performance. The class on the energy performance certificate (PENB) appears in adverts, so buyers compare it directly.
- Form of ownership. Personal ownership and cooperative shares are valued differently.
- Occupancy. A flat with a tenant is a different product from a vacant one.
Common valuation mistakes
Sellers commonly add the cost of their renovation to the price, crown for crown. Buyers do not pay for your taste; they pay for what they will use. Our guide to preparing a flat for sale separates the work that moves offers from the work that does not. Another frequent error is to price on the basis of what the next flat costs. A third is to start high "to leave room to negotiate" and then lose the first, most active weeks of the listing.
Remember that the buyer's lender will want its own valuation and that a price far above the comparables can fail on that test, whatever the buyer is willing to pay.
Putting the figures together
A workable approach is to take the range from comparables, check it against two broker estimates and an online figure, and adjust for the particular strengths and weaknesses of your flat. Pick an asking price near the top of the credible range, and decide in advance how long you will test it, and what you would accept. Fix those two decisions before the first viewing and you will negotiate with a cooler head.
Frequently asked questions
Frequently asked questions
Is an online estimate accurate?
It gives a range, not a valuation. It cannot see condition, view or the state of the building, so use it as a first step.
Do I need a formal appraisal to sell?
Not for an ordinary sale. It is useful in disputes, inheritances and unusual flats.
Why would the buyer's bank value the flat lower?
Banks value conservatively and for lending, using their own methods. A lower valuation reduces the loan, and the buyer may have to renegotiate.
Where can I find recent sale prices?
Brokers know local sales, and the cadastre holds registered contracts under its access rules. Check ČÚZK for what you can see (as of 2026).
Timing the market, and the cost of waiting
Sellers often ask whether to wait for a better price. Nobody can time a market reliably, and a decision to wait has its own costs: the mortgage payments, the service charges, the repairs that keep coming and the chance that the next flat you want will be sold to somebody else. If you can afford to wait, set a date and a trigger in advance, such as the next published index release from the Czech Statistical Office, and judge the flat against the data on that date rather than against hope.
It also helps to separate two questions. What is the flat worth today, and what do I need to get for it? The first is a market question, answered by the methods above. The second is a personal one, shaped by the loan on the flat and the price of your next home. A price that meets your need but not the market will not sell, and a price that meets the market may not meet your need. Knowing which gap you face tells you whether to adjust the price or the plan.
A first step this week
Write down ten flats you know sold nearby, how you learned of each sale and what you do not know about it. Then ask one broker to compare your list with theirs. The overlap is your starting evidence, and the next stages are laid out in how to sell a flat in Prague.
