PROPERTY CHECK QUESTIONS
Short answers. Clear boundaries.
We provide property information, not professional advice. This is not a valuation report or a loan approval.
01Is this a formal valuation?
No. We collect available data and organise documents. A formal market valuation requires a qualified expert.
02What does it cost to start?
One property is free. Report packs are purchased separately, once per property, including VAT. Subscriptions do not include report packs.
More about pricing and report packs03Do I need to sign in?
You need a free account for your property file, for saving and for purchases. You can sign in with Google or an email link.
04What do I get for €49?
A sales brochure from your details, photos and official data. One payment per property, VAT included. First PDF after payment and confirmation; regenerate instantly, without limits. We do not check its content.
05What do I get for €29?
Financing documents with sources and reference dates. One payment per property, VAT included. Usually ready within minutes after payment and order confirmation. No loan approval or formal valuation.
06Where do the figures come from?
Official sources, your inputs and labelled assumptions. Reference dates and retrieval dates are separate. Availability depends on the location.
07What if data is missing?
Missing data stays visibly open. You can add details and documents. An assumption does not become a confirmed fact about your property.
08What happens to my data?
Your dossier is private. We only share information with partners with your consent for the specific purpose.
