The Problem We Solve

You win on speed and on getting it right the first time. A down-valuation, a short lease no one caught, or an EPC below C can break a case days before completion, after all the work is done.

Most of the checking is still manual: a portal valuation, an old comparables feed, a separate EPC lookup. It costs hours per case, and the risks that matter are usually the ones the lender surveyor flags last.

What changes with Propalt

Outcomes you can rely on

01 · Case screening

Flag valuation risk at fact-find

Return an AVM with confidence band and comparable count against the purchase price. Surface the cases where the gap is wide enough to need a conversation before submission.

02 · Green lending

EPC and fabric at point of sale

Current rating, potential rating, wall and roof construction, heating system and age. Match the client to green product criteria without waiting for the survey.

03 · Buy to let

Rental estimate and gross yield for ICR work

Rental estimate, gross yield and local demand indicator alongside the valuation. Test the interest cover ratio before the lender's calculator does.

04 · Leasehold

Lease position before the lender raises it

Lease records and tenure where held. The short-lease refusal stops being a week-six surprise.

05 · Platform integration

Inside the adviser's existing screen

One API and an OpenAPI 3.1 spec. Property data appears in the fact-find rather than in a tool the adviser will not open.

06 · Directly authorised brokers

No integration at all

Every endpoint is available as an MCP tool in Claude and ChatGPT. Ask about an address, get the answer. No platform work, no contract, free tier.

29M UK properties valued, an average of 12 sold comparables behind each valuation, and 0.94 accuracy (R²) against real sale prices. Answers in about 98ms.
