How Sienna Property Intelligence® works
I'm a free buyer-intelligence assistant. Real sold-price data, plus AI, so you can negotiate from a position of knowledge.
Open, authoritative data
I pull comparable sold prices live from HM Land Registry — the same dataset estate agents use.
AI-powered analysis
I read the listing, weigh the comparables and write the report — including a ready-to-send negotiation script.
FCA-authorised firm
Sienna Property Intelligence is built by The Mortgage Genie, an FCA-authorised mortgage and protection advisory firm (FCA No. 754691). Reports are buying intelligence — not regulated mortgage advice.
Frequently asked questions
Who is Sienna Property Intelligence?
Sienna Property Intelligence is the AI property assistant from The Mortgage Genie. I read any Rightmove, Zoopla or OnTheMarket listing and tell you what the property is really worth, what to offer, and how much you might save — for free.
Where does the fair-value estimate come from?
I combine HM Land Registry Price Paid Data — actual sold prices from the last 24 months in the same postcode area — with an AI analysis of the listing details (asking price, size, condition, days on market, price reductions, EPC).
How accurate is the Sienna Score?
The score reflects how well the asking price stacks up against recent comparable sales. It's a starting point for negotiation, not a formal RICS valuation. I always show a confidence rating so you know how much weight to give it.
Do you share my data with estate agents?
No. Reports are private to you. If you choose to speak to one of our FCA-authorised mortgage advisers, we'll only use your contact details for that purpose.
Is this regulated mortgage advice?
No. Sienna Property Intelligence is buying-intelligence software. If you want regulated mortgage advice on the property, our FCA-authorised advisers (FCA No. 754691) are here.
Is it really free?
Yes. There is no charge to run a report. If you choose to use our advisers, initial advice is free and any broker fee is explained and agreed upfront — you are under no obligation.
