Where the evidence comes from
Three sources, in order of usefulness.
- Currently advertised comparables. Same area, similar size, similar condition. Filter as tightly as you can, then note the listing dates. A property advertised three weeks ago at a given price is not evidence that the price works, it is evidence that it has not worked yet.
- Recently let properties. Harder to find, and more reliable, because an achieved rent is a fact while an asking rent is an opinion. A good agent will show you what it has actually let in your street.
- Published market data. Citylets publishes quarterly rental reports for Scottish cities with average rents by property size and average time to let. Their Aberdeen report for the first quarter of 2026 showed an average rent of eight hundred and seventy eight pounds, an average of forty five days to let, and sixty eight days for four bedroom properties.
Why a valuation can mislead
A rental valuation is free, and it is also a sales pitch. Where three agencies quote and the highest figure tends to win the instruction, there is an obvious pull upwards.
That is not dishonesty and the number is not necessarily wrong. But ask the follow up: which comparable properties is this based on, how long did they take to let, and what would you advise if it has not let in three weeks. An agency with a considered answer is giving you a valuation. One that cannot produce comparables is giving you a number.
Some agencies publish a valuation accuracy score. On allAgents, Clan Gordon in Edinburgh shows ninety eight percent and We Let Properties in Manchester ninety six percent, which is a more useful signal than the headline rating for this particular question.
The arithmetic of an empty month
This is the calculation that settles most pricing arguments.
Take a property you believe is worth one thousand pounds a month. Pricing at one thousand and fifty and letting a month late earns you eleven months at one thousand and fifty, which is eleven thousand five hundred and fifty pounds. Pricing at one thousand and letting immediately earns twelve thousand.
The optimistic price costs four hundred and fifty pounds in year one, and it costs it again every time the extra void repeats. You also pay management commission on nothing during the void, and the property still needs heating, insuring and securing while empty, which some insurance policies restrict after a set number of consecutive empty days.
What genuinely moves the figure
- Condition, particularly kitchen and bathroom. The single largest lever, and the one most within your control.
- Energy rating. Tenants now read the running cost, not just the rent.
- Parking, in cities where it is scarce.
- Timing. Student markets run to a hard calendar. Family lets move around school terms. Listing at the wrong point in the cycle costs more than fifty pounds of asking price.
- Furnished or unfurnished, which depends entirely on who rents in that street.
- Pets and flexibility. Widening who can apply shortens the void, which is usually worth more than holding out for a premium.
Raising it later
Getting the opening figure right matters partly because increases are constrained afterwards.
In Scotland, one increase per twelve months with three months of written notice, on the correct statutory form, and the tenant can refer it to Rent Service Scotland. In England, increases follow the statutory process introduced by the Renters' Rights Act in May 2026. Neither system lets you correct a badly judged opening rent quickly.
And weigh the value of a good tenant staying. A reliable tenant who pays on time for four years is worth more than the extra twenty pounds a month that prompts them to look elsewhere, because their departure costs you a void, a marketing fee and a new set of unknowns.
Common questions
Should I just use the agency's valuation?
Use it, but check it. An agency competing for your instruction has an incentive to quote high, because the highest number often wins the business, and the correction comes later as a suggestion to reduce. Ask what the figure is based on and for the comparable properties behind it.
Is it better to price high and negotiate down?
Rarely. A listing that sits unlet loses its place in portal sort orders and starts to look stale to the people most actively searching. Reducing after three weeks usually achieves less than pricing correctly at the outset.
Can I charge more for a furnished property?
Usually a modest premium, and it varies by market. In student and young professional areas furnished lets can command noticeably more, while family lets often prefer unfurnished. Set against the premium the cost of the furniture, its replacement cycle and the fact that you then insure it.
