Most landlords know roughly what the house next door sold for. Far fewer, in our experience, have worked out what their rental is worth to the person most likely to buy it, another investor. Those are two numbers from two different sums, and the gap decides whether selling is worth doing and what to fix first.
In short
- A buyer targeting 7% gross pays about £250,100 for a rent of £17,508 a year; one targeting 6% pays £291,800 for the same rent.
- Every extra £1,000 of evidenced annual rent is worth roughly £12,500 to £16,700 on the price, for buyers targeting 8% to 6%.
- Paperwork, certificates and rent evidence move the price before cosmetic work does, because they remove a discount rather than adding a feature.
- Under the Renters’ Rights Act, an in-tenancy rent rise runs once a year through a formal Section 13 rent increase notice, which the tenant can challenge at the tribunal.
- Selling with vacant possession uses Ground 1A, the landlord’s selling ground: the tenancy must have run twelve months and the notice period is four months.
Two prices, one building
An owner-occupier prices a house against what similar houses sold for, because they are buying somewhere to live. An investor prices the same building against the rent it makes and the return they need. The building has not changed. The question asked of it has.
For a worked example, borrow the national averages. Average private rent for England was £1,459 a month in August 2026, and the average house price for England £293,000 in July 2026, both in the ONS bulletin of 16 September 2026. The two averages come from different samples, so treat the pairing as an illustration of the sum rather than a real property: £17,508 a year against £293,000 is a gross yield of 6.0%.
Now price that same rent the way a buyer does:
| Gross yield the buyer targets | Price |
|---|---|
| Buyer targeting 6% | £291,800 |
| Buyer targeting 7% | £250,100 |
| Buyer targeting 8% | £218,850 |
The rent never moved. The price moved £72,950 on nothing but the buyer’s required return.
That spread is the most useful thing a landlord can understand before selling, because it runs both ways. A buyer needing a higher return pays less for the same rent.
Lift the rent and the same arithmetic pays you more: at these yields, every extra pound of evidenced annual rent is worth roughly £12.50 to £16.67 on the price.
The return a buyer demands is set by the area, the asset and what else their money could do. The income is the part you control.
What moves the investor price
Because the sum starts with rent, whatever makes it look reliable moves the price up, and whatever makes it look fragile moves it down.
Rent evidence comes first. A rent documented, paid on time and close to market is taken at face value. One below market after years without a review is priced on what it is, not what it could be, unless you can show the headroom is real. Our note on what a gross yield hides covers the deductions that come off next.
Then the things that cost the buyer money on day one. Arrears, an unprotected deposit, missing gas or electrical certificates, an unlicensed HMO, an EPC below the current lettable minimum or one a buyer expects to have to upgrade for rules still coming.
None of these stop a sale. All of them get priced, and they get priced on the buyer’s estimate of the cost, not yours. That estimate is usually the higher of the two.
Condition is the item landlords most often misjudge. An investor is not comparing your kitchen to their taste, they are costing the works needed to keep it lettable. A tired but sound property prices calmly. One whose condition is unknown prices defensively.
What is worth fixing first
Paperwork, because it is cheap and removes a discount rather than adding a feature. Get the deposit protection, certificates, licence and tenancy file in order before anyone asks. A buyer who has to chase it assumes more is missing.
Rent, because paperwork and condition remove discounts while rent lifts the number they are discounted from. Where there is genuine headroom, closing the gap between your passing rent and local new-let evidence does more than cosmetic work costing the same.
Under the Renters’ Rights Act an in-tenancy rise runs once a year through a Section 13 notice, the formal rent increase notice, which the tenant can refer to the tribunal, so it is a slower lever than it was and worth starting early.
How far it carries depends on the area.
Where investors buy at 6%, per extra £1,000 of rent
£16,700
Where investors want 8%, per extra £1,000 of rent
£12,500
Same work, different payoff, so know your market before you spend.
Cosmetics last. Refurbishing to owner-occupier taste rarely recovers its cost when the buyer intends to let, because they are not buying a home.
When selling empty is worth considering
If the owner-occupier comparable sits well above the investor figure, vacant possession can be worth the wait, and where a property would suit an owner-occupier the gap can be wide.
It is slower and more committed than sellers expect. Since 1 May 2026 it runs through Ground 1A of the Housing Act 1988, the selling ground, which needs the tenancy to have run twelve months by the date the notice names for proceedings, not the day it is served.
The costs are specific: the notice period is four months, a minimum rather than a fixed term. Once the ground is used, section 16E bars letting or advertising to let for the restricted period defined in section 16M: twelve months after the date the notice names, about sixteen months from service on a four-month notice. A sale that collapses in that window leaves an empty property you cannot re-let.
The mechanics are in our piece on possession after Section 21. That is general information, not advice on your tenancy, so take legal advice before planning a sale around it. Price the tenanted route first, then decide if the gap justifies it.
What this means for property investors
Do the sum before you form a view. Divide the annual rent by 6%, by 7% and by 8%, as in the example above. The yield a buyer asks for varies with the area and the asset, so check what comparable investment sales nearby have achieved.
Compare that with a local comparable for the property empty. Both are before selling costs and tax, which differ by seller and can change which route nets more, so take advice on your own position. If the two are close, selling tenanted keeps the rent running until completion. If the gap is wide, the vacant route earns a look.
For a buyer, the same arithmetic backwards is why the rent, not the street, should set your offer. Where a seller has priced against the comparable, the gap is a conversation to have openly rather than an advantage to sit on.
