Good questions.
Which listing sites work?
Hemnet, Booli and agent sites, plus most agent listing pages.
Does it work for couples?
Yes, that’s the point. Invite your partner to your household and see each other’s read on every home, side by side. No more long WhatsApp threads.
Does it work if I’m also selling?
Yes. Add your current home and see what you’ll walk away with after fees, tax and loans, and whether to sell or buy first. Your whole move in one place.
How reliable is the verdict?
It’s built from the facts in the listing, and we always show what’s known and what’s missing. A sharp first filter, not a replacement for a professional inspection.
Whose side is Heimer on?
Yours. Heimer is here for you, the buyer. We show what a home costs, what the risks are, and what to do next.
Is my data safe?
Yes. We never sell your data. Your listings and results are private to your account, and you can delete everything anytime.
What does a home really cost per month?
The real monthly cost is interest plus amortization plus fees or operating costs plus maintenance. Heimer works out all four from the listing, so you see what the home actually costs each month, not just the asking price.
What should I check before bidding on a home?
Check the true monthly cost, the building’s finances, the build-year risks like roof, drainage and electrics, and any inspection notes. Heimer surfaces all of these from the listing and gives you a checklist for the viewing.
How do I read a building’s or association’s finances?
Look at debt per square metre, savings, and upcoming maintenance such as pipe replacement. Heimer reads the association’s finances for you and flags the risks before you bid.
Numbers you can trust
We keep track of what needs checking and fixing, so you don’t have to hold it all in your head.
- Every number can be adjusted, and you see what it builds on.
- When a figure is missing we say so, rather than guess.
- Amounts, rules and thresholds are checked against official sources.
Feel confident in your biggest decision.
