If you are thinking about letting your home, start with a range rather than a single perfect figure. Look at similar homes advertised nearby, adjust for the differences, and check your conclusion with someone who knows the local market. The rent you eventually agree will depend on the home, the terms offered and demand at the time.
For a starting point in England, try the free Bellsoph rental valuation. It uses your property details, advertised comparables and official data to provide an initial estimate. Then use the steps below to test whether that estimate fits your particular home.
Start with genuinely comparable homes
Search current local listings for homes a prospective tenant might consider instead of yours. Start close to your property and widen the area if there are too few useful examples. Keep the search recent: a listing from months ago may describe a different market. Aim for around five useful examples where available, but do not force poor matches to reach a number. Remove duplicate adverts for the same home. RICS guidance on comparable evidence emphasises recent, similar and verifiable comparisons.
Compare property type and bedroom count first, then look more closely at floor area, layout and bathrooms. Two homes with two bedrooms can feel very different if one has a small second bedroom or much less living space. Record the advertised monthly rent, location, date, furnishing and any included bills alongside the listing link.
Consider the features a tenant will actually experience: condition, kitchen and bathroom quality, outdoor space, parking, energy efficiency, transport links and proximity to amenities. A newly renovated flat next to a station may not be a good direct comparison for an older flat farther away, even if the bedroom count matches. Avoid treating every difference as having a fixed monetary value; use your judgement and seek local advice where the evidence is thin.

Asking rent is not necessarily the rent agreed
An advertised rent is the landlord's asking price. It shows the price at which a home is being marketed, not proof of what a tenant ultimately pays. A listing marked “let agreed” can show that a letting is progressing, but its displayed price does not establish the final agreed rent or whether the tenancy completed. A listing that remains online may also be outdated or duplicated.
Ask local letting agents for recent, genuinely comparable completed lettings and how similar they were to your home. They may not be able to disclose individual figures; ask what evidence supports their suggested range and when the lettings took place. Compare more than one view if possible.
Official data adds useful context, but an area average is not a valuation of your individual home. The ONS private rents methodology covers both new and existing tenancies, so it should not be treated as a direct measure of today's asking rent for your particular property.
Turn the evidence into a realistic range
Put the closest comparisons together and note where your home is stronger or weaker. Give the most weight to recent homes that match on location, size, type and condition. Use the resulting range as a working estimate, then decide where within it your home sits. If there are few close matches, widen the range and be more cautious.
For example, hypothetically, imagine an ordinary two-bedroom flat without parking. Two similar flats are advertised at £1,250 and £1,300 a month, a smaller flat at £1,200, and a refurbished flat with parking at £1,450. A working range of £1,250–£1,300 may be a sensible starting point to discuss with an agent. The properties and figures are invented, not a Bellsoph result, market evidence or a promise of rent. Check whether the examples are still available, whether their terms match yours and whether any completed letting evidence supports the range.
A higher asking price is not automatically a better outcome. Consider the possibility of an empty period and the cost of preparing the home alongside the proposed rent. Once you have a range, the monthly cash-flow calculator can help you explore the effect of different rent and cost assumptions.
What if you are letting rooms or a block?
A whole-home comparison is a weak guide to an individual HMO room. Compare similar rooms, including room size, shared facilities, occupancy, furnishing and whether bills are included. Room-by-room income also needs its own allowance for costs and empty periods. An initial whole-home estimate should not be treated as an HMO valuation.
For a multi-unit block, assess each unit against comparable homes and consider the condition and letting position of each one. A single estimate for the building will not capture different layouts, existing rents or vacancies. Ask a local professional with relevant experience for a property-specific assessment where the decision depends on it.
Check your estimate before you advertise
Save your comparison notes and dates, review the range as market evidence changes, and ask an agent to explain any material difference from your own estimate. Be clear about furnishing, bills and the condition in which the home will be offered. The final figure is a commercial judgement, not a guaranteed outcome.
