How to vet an interested investor as a property sourcer

Published: 24 August 2026 · Last updated: 24 August 2026

Kinmoot doesn't vet investors before they register interest, so that job sits with you once you unlock the list. Ask for proof of funds or a mortgage Agreement in Principle before you invest real time, check any limited company buyer against Companies House, watch for the common signs of a time-waster, and don't take a deal off the market until there's a firmer commitment than a registered interest.

Why vetting is on you, not the platform

Kinmoot is a marketplace: any registered investor can register interest in a listed deal, and that action is free and instant. It's a good filter for reach — it puts your deal in front of people actively looking — but it isn't a filter for seriousness. Some of the investors who register interest will be ready to move immediately; others will be browsing, comparing, or simply curious. Telling the two apart is your job, exactly as it would be with a lead from any other channel. If you haven't unlocked your investor list yet, see what happens after you post a deal for how that step works.

What to ask for before you invest real time

Before you go deep with an interested investor — sharing full documents, negotiating terms, taking the deal off other conversations — ask for evidence they can actually complete:

  • Cash buyers — a recent, dated bank statement or a solicitor's/accountant's letter confirming funds are available. A screenshot with no name or date proves little.
  • Mortgaged buyers — an Agreement in Principle (AIP) or Decision in Principle (DIP) from their lender. This confirms a lender has already assessed them, not just that they intend to apply.
  • Company buyers — the company name and number, so you can check it independently rather than taking it on trust.
  • A named solicitor — even at an early stage, a serious buyer can usually name who'll act for them, or say they're in the process of instructing one.

Checking a company buyer

Many property investors buy through a limited company or SPV, which is entirely normal — it isn't itself a red flag. What matters is that it checks out: search the company on Companies House, confirm it's active, see how long it's been registered, and check the director names match who you're actually speaking to. A very recently incorporated SPV is common for a first purchase through a company and not a concern on its own.

Signs an investor isn't serious

None of these alone rules someone out, but two or three together are a strong signal to stop prioritising them:

  • Won't provide any proof of funds after a reasonable amount of back-and-forth.
  • Vague or inconsistent answers about how they're funding the purchase.
  • Long silences, then reappearing wanting to restart the conversation from scratch.
  • Repeatedly renegotiating price or terms before a solicitor is even instructed.
  • Pushing to skip standard steps — viewing, valuation evidence, legal checks — to move faster.

Protecting the deal while you're in conversation

Registering interest costs an investor nothing, so don't treat it as a reason to stop showing your deal elsewhere. Keep talking to multiple interested investors in parallel until one of them backs their interest with something firmer — a reservation fee, signed terms, or a solicitor instructed. Only then does it make sense to prioritise one buyer over the others.

  1. Register interest received — treat as a lead, not a commitment.
  2. Request proof of funds or AIP/DIP, and company details if relevant.
  3. Verify what's provided — Companies House, dated documents, a named solicitor.
  4. Once verified and terms are agreed, take a reservation fee if that's your process before pausing other conversations.
  5. Proceed to legals and completion.

Next steps

If you haven't unlocked your interested investors yet, do that first — see what happens after you post a deal for the full process. And if you're new to sourcing altogether, what is property deal sourcing is a good place to start.
