How it works · 3

Decide whether it is worth continuing

Use the result to see what to verify before a viewing and what to ask the agent.

Monthly housing costs

We combine the estimated mortgage payment, building fees, and a repair reserve.

Cash you need

See the down payment, one-time purchase costs, and the reserve you want to keep.

Risks to verify

We highlight fees, apartment and building condition, ownership, documents, and mortgage terms.

Price context

See the purchase price, price per m², and any available indicative local context. This is not a professional valuation.

Documents and ownership

Legal, technical, mortgage, tax, and HOA checks remain explicit next steps outside the score.

Input confidence

Imported or missing values stay unverified until you confirm price, area, fees, ownership, and address.

Location, area, condition, and other requirements are checked without changing the rules.

FAQ

Before you calculate

Short answers about what BytScore can do, what it cannot do, and when manual entry is enough.

Open full FAQ

Is BytScore a market price estimate?

No. BytScore is a preliminary check. For your own home it shows monthly costs, cash needed, risks, and details to verify.

Do I have to register?

You can get the first preliminary result without registration.

What if I do not know the fees or mortgage terms?

You can start with an estimate and adjust the details later. We mark unverified values in the result.
