Asking rents are easy to find and systematically optimistic. Signed evidence is harder to obtain and far more reliable. This compares both and sets out how to use each.
Asking rent is what an owner advertises. Achieved rent is what a tenant signed, after negotiation, incentives and however long the unit stood empty. In a model, only the second is an input you can defend, yet the first dominates most underwriting because it is free and instantly available. The difference between them is not a rounding error, and it compounds because the exit value is usually derived from the same rent.
Asking rents at a glance
Asking rents come from listing portals, agents' boards and developer price lists. They are abundant, current and cover almost any district you care about, which makes them genuinely useful for orientation. What they cannot tell you is whether anyone agreed to pay them, how long the unit has been advertised, what was conceded to close a deal, or whether the advertised unit resembles the one you are underwriting.
Signed rent evidence at a glance
Signed evidence means registered tenancy contracts and the building's own letting record: what was agreed, when, for which unit, on what terms and after how many days of marketing. It is harder to assemble because it sits with owners, managers and registration records rather than on a portal. In exchange it tells you what the market actually paid, which is the only thing a model can honestly capitalise.
What it measures
Asking rents: An owner's expectation at a point in time, before negotiation and before the unit was tested by the market.
Signed rent evidence: A completed transaction, including whatever the owner conceded to achieve it.
Availability
Asking rents: Immediate and broad, covering districts and unit types you have no other access to.
Signed rent evidence: Limited and slow, depending on the cooperation of owners, managers and registration records.
Direction of bias
Asking rents: Consistently optimistic, because an owner lists above the figure they expect to accept.
Signed rent evidence: Close to neutral, though a single transaction can reflect an unusual tenant or an unusual motivation.
Visibility of incentives
Asking rents: Almost none, so a rent-free period or a fit-out contribution is invisible in the advertised figure.
Signed rent evidence: Visible if you read the contract, which is precisely why you read the contract rather than a summary.
What it tells you about timing
Asking rents: Only indirectly, through how long the listing has been live, which is often unreliable.
Signed rent evidence: Directly, because the gap between a unit falling vacant and the new contract starting is measurable.
Weight in a valuation discussion
Asking rents: Low, and an accredited valuer will say so when the evidence is tested.
Signed rent evidence: High, especially where several transactions cluster and can be adjusted onto a common basis.
Effort to use properly
Asking rents: Low, which is the whole attraction and also the reason it is overused.
Signed rent evidence: Substantial, since each transaction needs adjusting for size, floor, finish, age and terms.
When asking rents wins
- Getting a first sense of a district you do not know before committing time to it.
- Spotting the range of rents on offer and therefore where your unit might sit.
- Identifying competing supply and how long it appears to have been available.
- Setting an upper bound against which to sanity check an optimistic assumption.
When signed rent evidence wins
- Setting the rent assumption that carries the income line and the exit value.
- Supporting a price argument with transactions rather than opinions.
- Showing a lender or a co-investor where the income forecast comes from.
- Detecting incentives and rent-free periods that make a headline rent misleading.
- Measuring how long units of that type take to let, which feeds the vacancy allowance.
How to decide
Capitalise only signed evidence. Use asking rents to shape your search, to understand competing supply and as a ceiling, never as the rent in your base case. Where signed evidence is thin, do not substitute asking rents; instead narrow your assumption to the units you can evidence, widen your vacancy allowance to reflect the uncertainty, and reduce the price you are willing to pay by the value of the evidence you could not obtain.
Assemble a comparables schedule in which each line carries the date of the contract, the unit area, the floor, the finish standard, the lease length, any rent-free or discount period, the service arrangement and who paid utilities. Then convert every line onto one basis before comparing, because an unadjusted schedule is a list rather than evidence. Where the figure matters to a lender or a partner, an accredited valuer working through Taqeem will expect to see the same discipline, and anything that depends on tenancy registration practice should be confirmed against current requirements, which are updated from time to time.

Frequently Asked Questions
How do I find achieved rents rather than advertised rents in Saudi Arabia?
Work through the parties who hold transaction records: the building's own manager, managers of comparable buildings, the tenancy registration record for contracts you are entitled to see, and agents who will share what they have let rather than what they are marketing. The subject building's own letting history is usually the single best source, since it describes the same product in the same location.
How much lower are achieved rents than asking rents?
There is no reliable general answer, because the gap depends on how much competing supply exists, how long units are taking to let and how motivated owners are at that moment. The practical approach is to measure the gap yourself on units where you can see both the advertisement and the eventual contract, then apply what you measured rather than a rule of thumb borrowed from another market or another year.
Can I use a valuation report as my rent evidence?
A report from an accredited valuer is a useful cross-check and often cites the evidence it relied on, which is the part worth reading. It is not a substitute for assembling your own schedule, because the valuer answered a question defined by whoever instructed them, on a date that may not be recent. Read the evidence section, test whether it describes your unit type, and build your own comparison from it.
