Market Rent Assessment
A property-specific AI lettings evidence report that establishes whether a proposed rent is supported by the open market. Used by landlords, tenants, and letting agents to settle rent increase discussions with data rather than opinion.
What is a Rental Assessment?
A Rental Assessment is a written evidence report produced for a specific address. It uses live and recent comparable rental listings, transport and amenity scoring, and AI analysis to establish a calibrated rent range for your property — the range within which comparable properties are currently being let in the open market.
It answers a single, critical question: is the proposed rent supported by what similar properties are actually achieving nearby? If you are a landlord, it tells you whether your proposed increase is defensible. If you are a tenant, it tells you whether the increase is above market rent and worth disputing.
What does the report include?
- Comparable listings — a curated set of similar properties currently or recently let near your address, with rents, distances, and key attributes
- Calibrated rent range — a lower, mid, and upper bound based on what the comparable evidence supports for your specific property type and location
- AI commentary — a plain-English explanation of the evidence, noting any factors that push the range up or down (transport links, local amenity, property condition)
- Transport and local scoring — an objective assessment of proximity to stations, schools, and key amenities
- Downloadable PDF — a formatted report you can share with a landlord, tenant, or letting agent
Who is it for?
Landlords considering a rent increase: use the assessment to check whether your proposed figure is in line with comparable evidence before serving a notice. A rent pitched in line with the market is easier to justify and less likely to be challenged.
Tenants who have received a rent increase notice: use the assessment to understand whether the proposed rent is above market rent. If it is, the report provides evidence you can use when negotiating with your landlord or preparing to refer the increase to the First-tier Tribunal.
Letting agents and advisers who need a quick, documented evidence base for rental discussions without commissioning a formal RICS valuation.
How does it work?
You enter a postcode and bedroom count. The system looks up the address, pulls comparable rental listings from the surrounding area, scores transport links and local amenities, and produces a written evidence report — typically in under five minutes. You pay £29 at checkout and the report is immediately accessible in your account.
Is this the same as a formal valuation?
No. A Rental Assessment is market evidence, not a formal RICS Red Book valuation. It is well-suited to resolving private rent increase discussions and providing background evidence for tribunal proceedings. If you need a report signed by a RICS-qualified surveyor — typically required as primary evidence in formal tribunal proceedings — the Tribunal Evidence Pack is the appropriate product.

- Enter your postcode and bedroom count — the system identifies the subject property location and pulls comparable rental listings from the surrounding area.
- Comparable data is gathered — PropertyData, Realyse, and AI web search sources are queried in parallel for similar properties currently or recently let nearby.
- Adjustments are applied — each comparable is adjusted for differences in recency, size, bedroom count, and furnished/unfurnished status.
- Outliers are removed — the IQR method filters statistical outliers, and the adjusted rents are ranked to produce a P25/P50/P75 calibrated range.
- AI commentary is generated — an AI model reviews the evidence and writes a plain-English confidence statement and market context note.
- Report delivered — pay £29 at checkout and access your report immediately online; a PDF download link and report link are sent by email.

Frequently asked questions
Is a Rental Assessment the same as a formal RICS valuation?
No. A Rental Assessment is a market evidence report, not a regulated RICS Red Book valuation. It is appropriate for resolving private rent increase discussions and providing background evidence in tribunal proceedings. If your specific circumstances require a RICS Red Book valuation, seek independent RICS-qualified advice. For formal tribunal use with professional sign-off, the Tribunal Evidence Pack is the appropriate product.
How quickly is the report ready?
For most England postcodes, the Rental Assessment is generated in under five minutes after checkout. Once complete, the report is immediately accessible online and a link is sent to your email address. There is no waiting period — the system generates your report automatically.
Can I use this report as evidence at the First-tier Tribunal?
You can submit a Rental Assessment as supporting evidence at the First-tier Tribunal (Property Chamber). However, it is an AI-generated report with no human review. For stronger, more credible tribunal evidence, the Tribunal Evidence Pack (£175) includes expert review and sign-off, and is structured specifically for tribunal submission.
What if there are not many comparable properties near me?
In areas with limited comparable data, the system automatically widens the search radius and includes adjacent-bedroom properties with adjustments applied. The confidence score in your report will reflect data availability — a lower score indicates a wider margin of uncertainty. If the report cannot gather sufficient comparables, you will see a clear data availability notice.
Does the report cover furnished and unfurnished properties?
Yes. You specify whether the property is furnished or unfurnished when ordering, and the valuation engine applies a furnished/unfurnished adjustment when comparing properties with different furnishing status. The adjustment step is shown in the per-comparable waterfall section of the report.
Can I get a report for a property outside London?
Yes. Rent Report covers all England postcodes. Outside London, the comparable search radius is widened to 1.5 km (from 1 km) to account for lower property density. Data coverage is strongest in London and major urban areas; rural and low-density areas may produce lower confidence scores.
What data sources does Rent Report use?
Rent Report pulls comparable listing data from the PropertyData API (aggregating Rightmove, Zoopla, and OnTheMarket), the Realyse API, and an AI-powered web search (OpenAI + Perplexity). Floor areas are enriched from the EPC Open Data API. Transport and amenity scoring uses OpenStreetMap. Government benchmarks come from the ONS Private Rental Market Summary.
