The rent figure decides the deal. So stop guessing it.
A rental estimate drawn from letting comparables, with a local demand indicator and the gross yield at both asking and offer price.
Propalt Team · For property investors
Every buy-to-let decision turns on one number you do not control at the point of offer: the rent. Get it wrong by fifty pounds a month and the yield you underwrote does not survive contact with the tenancy. Yet the usual way to find it is to ring a letting agent, who has an interest in a high figure to win the management, and take their word. That is not a rental estimate. That is a sales pitch with a number attached.
An instant yield check replaces the phone call with a figure grounded in what comparable properties nearby actually let for. It comes with a local demand indicator, so you are not only told a rent, you are told whether a property at that rent is likely to move quickly or sit. A high rent in a slow pocket is a void risk dressed up as a good yield.
A rent you can defend, and a yield you can underwrite
The estimate is only useful if it stands up when you build the model around it. That is why it leans on letting comparables rather than a single agent's opinion, and pairs the rent with the gross yield against whichever price you feed it, the asking figure or the number you actually intend to offer. You see the deal at list price and the deal at your price side by side, which is exactly the comparison that decides whether to bid.
The demand indicator does the second job an agent's number never gives you. Rent is half the story; how fast that rent lets is the other half. A property that lets in a fortnight and one that lets in three months can quote the same monthly figure and produce very different real returns once voids are counted.
| Address (illustrative) | Est. rent pcm | Demand | Yield at asking | Yield at offer |
|---|---|---|---|---|
| Flat, city centre | £950 | High | 6.3% | 6.8% |
| Terrace, suburb | £825 | Moderate | 5.9% | 6.4% |
| Semi, edge of town | £775 | Low | 5.2% | 5.6% |
The figures are illustrative. The point is that the yield moves with your offer, and the demand column tells you which of these you would actually want to hold.
One address, an answer in seconds
The workflow is deliberately short. You give an address and, if you have one, an offer price. Back comes the rental estimate, the demand indicator and the gross yield at both prices. There is no waiting on a callback, no polite scepticism about whose number to trust, and no manual division on the back of a viewing note.
The letting agent gets paid whether the yield works or not. You do not.
For a fast market where offers go in on the day of the viewing, that speed is the whole value. You can walk out of a property, run the check on the pavement, and know whether the rent supports the price before the next buyer has finished parking.
Check the rent yourself, before you offer.
