Setting the Right Rent

Setting the right rent means finding the figure that clears your yield target without sitting so far above local comparables that the property sits empty while you wait for a tenant. Price too low and you are giving away return every month for the life of the tenancy. Price too high and the void period while it sits unlet, plus the eventual rent you settle for anyway, can cost you more than a modest, realistic figure would have from day one.

This guide sets out how to build a rent figure from genuine local comparables, how to weigh that figure against your yield target, why time on market matters more than the headline number, and how often to revisit the rent once a tenancy is running.

Local comps

The most reliable way to set a rent is to look at what genuinely comparable properties are actually achieving, not asking, in your immediate area right now, rather than relying on a national average or a figure from a year-old letting.

A useful comparable set matches on:

• Size and layout. A two-bedroom flat with a small second bedroom is not comparable to a two-bedroom flat with two doubles, even on the same street.
• Condition and specification. A recently refurbished kitchen and bathroom, or a higher EPC rating with lower running costs for the tenant, can justify a rent above a tired but otherwise similar property nearby.
• Exact location, not just postcode. Being on the quieter side of a street, or a five-minute rather than fifteen-minute walk from a station, can move achievable rent noticeably within the same small area.
• Furnished versus unfurnished, since this affects both the tenant pool you are competing for and the rent they will reasonably pay.

Checking three to five genuinely comparable current listings, not historic ones, gives a realistic range rather than a single guessed figure. If your figure sits meaningfully above every comparable you can find, it is worth asking what specifically justifies that premium, a genuine improvement to the property, or simply hope, before advertising at that price.

Yield target

Local comparables tell you what the market will pay; your yield target tells you what you need the property to earn to make sense as an investment. Where these two figures disagree, it is worth understanding why before defaulting to whichever number is higher.

If comparables suggest a rent below your target yield, that is useful information about the specific property or area, not a reason to advertise above the market and hope. Our guide to what counts as a good rental yield in the UK sets out realistic gross and net benchmarks by area and property type, which is worth checking before assuming a property should be able to hit a particular figure simply because a spreadsheet says so at the point of purchase.

A worked example shows how this plays out. A landlord bought a two-bedroom flat expecting a 6% gross yield based on rent projections from eighteen months earlier. Current comparables in the immediate area now suggest £950 a month is achievable, giving 5.4% gross on the current property value, below the original target. Advertising at the originally hoped-for £1,050 instead, purely to hit the target yield, risks a longer void while the property is priced above what the current market will actually pay, which can easily cost more in lost rent than the extra £100 a month would have earned if it had let immediately. The realistic response is either accepting the lower yield the current market supports, or looking at what would genuinely justify a higher rent, such as a refurbishment, rather than pricing against a target the market is not currently paying.

Time on market

A rent set even 5% to 10% above the top of the realistic comparable range can add weeks to how long a property sits empty, and that void period costs far more than the marginal rent gained once the property eventually lets, often at a similar figure to where it should have started.

The maths is straightforward but easy to underweight in the moment: a property renting for £1,000 a month that sits empty for an extra four weeks while overpriced has lost roughly £920 in rent (assuming a typical month), which at that point cancels out more than a year of a modest £75-a-month premium even if the higher rent had actually been achievable, which it usually was not, since the void itself is often the direct result of the price being wrong. Our guide to reducing void periods covers the wider set of factors, beyond price, that keep a property letting quickly.

A practical rule many experienced landlords use: if a property has not had a serious enquiry within the first one to two weeks of listing at a given price, that is a signal to review the figure rather than waiting it out on principle. The market is telling you something a spreadsheet projection cannot.

Review cadence

Once a tenancy is running, rent should be reviewed periodically rather than left untouched for years or increased reflexively every time a renewal comes around. Since the Renters' Rights Act reforms took effect on 1 May 2026, a rent increase can only be proposed once every 12 months per tenancy, using the formal Section 13 process with at least two months' written notice, and a tenant who believes the proposed figure is above market rate can refer it to the First-tier Tribunal before it takes effect. Our guide on how much a landlord can increase rent covers that process and the tribunal risk in detail.

A sensible review cadence looks like this:

1. Check comparables annually, even if you do not intend to increase rent every year, so you know where the property sits relative to the current market rather than relying on a stale figure from the last review.
2. Increase when the gap to genuine comparables becomes meaningful, rather than by a routine percentage applied out of habit. A proposed increase backed by real comparable evidence is far better placed to survive scrutiny, whether from the tenant directly or a tribunal referral, than a round-number uplift with no supporting evidence.
3. Keep a record of the comparables used for each review, including screenshots or notes of specific listings, so you have evidence ready if an increase is ever challenged.
4. Weigh a good tenant's value against a small rent gap. A reliable, long-standing tenant paying slightly below the current market rate is often a better outcome than a shorter void followed by a new tenant at the top of the market, once turnover costs and risk are factored in.

Treating rent-setting as an ongoing, evidence-based process rather than a one-off decision at the start of a tenancy is what keeps a property earning close to its realistic potential without pricing it out of the market at any single point.

Property HQ tracks each property's rent history alongside your portfolio's net yield, so you can see at a glance which properties are due a comparables-based review and how a proposed change would affect your overall return before you serve a Section 13 notice.
