What we check

We verify the deal, not the story about it.

A sourcer brings us a lead at a price. That is the beginning of our work, not the end of it. Before a deal reaches a member we check it in two stages, in this order, and a deal that passes the second but not the first does not go live.

Stage one

The source

Whether this deal is real. Numbers are easy to produce for a property nobody can actually buy.

  • The vendor

    Who is actually selling, and on what basis we know it.

  • Vendor contact

    That we have reached them, not only the agent.

  • The agent

    Who is acting, and that they are instructed.

  • Ownership

    That the seller is in a position to sell.

  • The agreed price

    That the vendor has actually agreed it. Both "Offer accepted" and "More left in" require this; a deal without an agreed price is "Early" — see below.

Stage two

The numbers

Only once the deal is known to be real.

  • Comparables

    What similar property actually sold for, not what was asked.

  • Value after works

    The figure the whole appraisal rests on.

  • Refurbishment

    Costed, with the basis recorded.

  • Title

    Anything on it that changes what you can do.

  • Rent

    For anything that ends in a refinance.

  • Planning

    For development and land.

What the figures include

Deducted before the number is shown

This is where most published property returns quietly overstate. Ours deduct all of it before the number is shown.

On a purchase

  • Stamp duty, including the additional-property surcharge
  • Legals and survey
  • Finance: interest across the works and the lender’s arrangement fee
  • Holding costs while the works run — council tax and utilities
  • Selling costs where the exit is a sale — the agent’s fee and legals

On a rental

  • Letting agent fees
  • Maintenance
  • Voids
  • Buildings insurance
  • Mortgage cost after refinance, and the set-up fee on the new loan

We publish gross yield and net yield side by side. The gap between them is usually large, and it is the honest one that tells you whether a deal works.

A worked example

A flip from our own pipeline, with the numbers left in.

Purchased in August 2025, refurbished, listed, and now sold subject to contract. This is the sheet we would show a member: what went in, what it is listed at, and the gap between them with everything it leaves out printed underneath.

Three things are missing on purpose: the address, because the area is enough; the photographs, because they belong to the selling agent; and a profit, because the sale has not completed and stamp duty, finance, legals and selling costs are not yet in the number.

£109,000

Listed price less purchase and refurbishment. It is before stamp duty on the purchase, finance across the works, legals and selling costs, so it is not profit. And it is not realised: the sale is agreed subject to contract and has not completed.

Two kinds of agreed deal

Every deal here has its price agreed. The colour says how much stays in.

A deal reaches a member once the vendor has agreed the price and we have confirmed it at source. What the colour and its word then tell you is the thing you actually weigh on a refinance: how much of your own money is still in the property after the new mortgage comes back.

Offer accepted

The price is agreed and, on a refinance, £20,000 or less of your money stays in. A sale that is agreed is green too. Our system will not let a deal be marked this way unless the agreed price has been confirmed at source — it refuses the change and names what is missing.

More left in

The price is agreed just the same, but more than £20,000 of your money stays in after the refinance. Amber is about the capital the deal holds, not about the price being in doubt — and the figure itself is the headline on the card.

A deal whose price has not yet been agreed with the vendor is marked Early, in a third colour, with the sentence “Not yet agreed with the vendor. Figures are Stream’s working assumptions.” The database decides the colour from the money left in and refuses a flag that contradicts the figures.

Registering interest

First come, first served — and no deal is done online

When a deal works for you, register your interest on its page. Interest is taken in the order it is registered, you are told your place, and we take the deal forward one to one in that order — the full pack, the vendor’s position, and then your decision. Nothing is bought or reserved on the hub itself. The one thing you can sign here is a non-disclosure agreement, where a deal needs one — it binds you to confidentiality and to nothing else.

What we are not

Not advisers, not a guarantee

Stream is an acquisition team and deal sourcer. We are not financial advisers, we do not give investment, tax or legal advice, and nothing on this site is a personal recommendation. Verification means we checked what we say we checked — it is not a guarantee of performance, and it is not a substitute for your own due diligence.

Where Stream owns a property it is being sold to you, and we say so on the deal itself rather than in small print. In that case we are the seller, not your agent.
