Sourcing tools vs underwriting tools

Sourcing tools find motivated sellers and off-market owners and help you write to them at scale. Underwriting is what happens when one of them says yes: what's it worth, what will it cost, and what's the most you should offer. Most people buy the first and improvise the second.

What a sourcing tool is for

Filters for motivated sellers, off-market owners and below-market listings, letter campaigns, a pipeline to track who you've written to. If your bottleneck is leads, you want one.

The expensive moment is the reply

A lead is free to get wrong. An offer isn't. When the owner calls back, you need the number in minutes, and you need to still believe it a week later when the survey, the finance and the solicitor have all had their say. That's underwriting, and it's a different job from sourcing.

What PropertyPredator does

If you already pay for a sourcing tool, keep it. When a lead replies, bring the address here for the number. See how it works, with the working shown →

Finding a deal is the easy half.

Whichever category you buy from, the expensive mistake comes when you decide what to offer. Overpay once by £10,000 and no subscription saving gets it back. So before you pay for any tool, run this on a property you already know.

  1. 1 · Pick a property you know the answers for.One where you know the owner, what it sold for and what's happened to it since. You're marking the tool's homework, not learning the property.
  2. 2 · Who owns it?Ask for the company behind the title and the people who run it. In PropertyPredator: Owner X-Ray names the company and its directors, for England, Wales and Scotland. A private owner's name is only on the official register copy.
  3. 3 · What's it really worth?Ask where the end value comes from. In PropertyPredator: real sold prices on the street, not asking prices.
  4. 4 · What's the most you should pay?Ask for a maximum offer worked back from the margin you need, with every cost line shown. In PropertyPredator: the Deal Analyser back-solves it, and your first one is free.
  5. 5 · Can you defend it tomorrow?Save the deal with its figures and come back to it. In PropertyPredator: saved deals, a pipeline and PDF reports, so the number you offered is the number you can show.
