Common questions

What does Heimer cost?

Your first analysis is free. After that, Premium is 349 kr a month for unlimited analyses.

Which sites work?

A link from Hemnet, Booli or most agent sites works fine.

Do you replace an inspection?

No. We get you ready for it. You'll know what's worth a closer look, so the inspection is worth more.

How do you know what might be wrong?

We start from the build year and what's known about homes from that time. We never claim a fault exists, we show what's worth checking.
