Bytky for property investors: where to start
In short
Bytky estimates what every flat for sale could rent for and what that returns on its asking price. The yield map and the area rankings show where the returns are, the calculator turns one flat into a monthly cash flow, and the price check works at any address. All of it is free and needs no account.

Open For investors
Features → For investors brings the five tools together, each with a short explanation and a link straight in.
Find the areas
The yield map colours the country by gross rental yield, and the rankings list every town and city part by it. Start there to see where flats return the most.

Shortlist flats
Sort a search for flats to buy by Highest yield, or set a Min. gross yield. Every flat for sale shows its estimated rent and gross yield.

Run the numbers
On a flat you like, Run the numbers adds a mortgage, running costs and income tax, and shows what's left each month.

Check any address
The price check shows what similar flats nearby ask to buy and to rent, and the gross yield of the two, for any flat in Czechia, listed or not.

Good to know
- Every figure comes from asking rents and asking prices, not what flats let or sold for, so a realised yield is likely a little lower.
- Each tool has a step-by-step guide of its own, linked below.
