What is a good rental yield in the UK?

A gross rental yield of 6% or above is generally considered good for a UK buy-to-let property. Yields vary significantly by location — northern cities like Liverpool, Manchester and Leeds often see yields of 7–9%, while London and the South East typically offer 3–5%. DealFlow AI flags any property yielding below 4% as a potential concern.

How do I calculate cash flow on a buy-to-let property?

Buy-to-let cash flow is your monthly rent minus all costs: mortgage payments, letting agent fees (typically 10–15%), maintenance allowance (around 1% of property value per year), insurance, and any void periods. DealFlow AI calculates all of this automatically when you paste a Rightmove link.

What EPC rating do I need to legally rent a property in the UK?

In England and Wales, a property must have a minimum EPC rating of E to be legally let. The government has proposed raising this to C for new tenancies, though this has been delayed. DealFlow AI automatically flags F and G rated properties as unlettable and highlights any EPC compliance risk.

How much stamp duty do I pay on a buy-to-let property?

Buy-to-let investors pay standard Stamp Duty Land Tax (SDLT) plus a 3% surcharge on each band. For example, on a £200,000 property in 2025 a BTL investor would pay approximately £7,500. DealFlow AI calculates your exact stamp duty figure automatically based on the asking price.

How do I know if a property deal is worth buying?

A good buy-to-let deal typically has: a gross yield above 6%, positive monthly cash flow after all costs, an EPC rating of D or above, no major planning issues nearby, and a strong local rental demand. DealFlow AI analyses all of these factors instantly and gives a clear BUY, MAYBE, or AVOID verdict scored out of 100.

Is DealFlow AI free to use?

Yes. DealFlow AI is completely free to use with no account required. You get 5 property analyses per day on the free tier, including the full AI verdict, yield calculation, EPC check, stamp duty figure, mortgage cost, and cash flow estimate.

How does the free Rightmove analyser calculate rental yield?

DealFlow AI estimates monthly rent for the property using local comparable rentals, then divides the annual rent by the asking price to give a gross yield percentage. A good UK buy-to-let yield is typically 6% or above.

Does the analyser work with all Rightmove listings?

Yes — DealFlow AI works with any residential property listed on Rightmove across England, Scotland and Wales, including houses, flats, terraces and new builds. Simply paste the full property URL.

What stamp duty does the tool calculate?

DealFlow AI calculates the full Stamp Duty Land Tax (SDLT) including the 3% buy-to-let surcharge that applies when you already own a property. The figure is shown instantly alongside the other deal metrics.

Can I use it to analyse properties for flipping, not just buy-to-let?

Yes. DealFlow AI includes a Flip Finder mode that estimates renovation costs, gross development value (GDV) and projected net profit for properties that might suit a fix-and-flip strategy.

What the Free Rightmove Analyser Gives You

Every free analysis includes the metrics that actually matter for a buy-to-let decision:

Gross Rental Yield

Estimated annual rent divided by asking price. Flagged green above 6%, red below 4%.

Monthly Cash Flow

Rent minus estimated mortgage, agent fees, maintenance and voids — shown in £/month.

EPC Rating

Current EPC band pulled from the listing. F and G rated properties are flagged as unlettable.

AI Verdict

A clear BUY, MAYBE or AVOID based on all the above metrics — no ambiguity.

Flip Estimate

Optional flip analysis: estimated reno cost, gross development value and projected net profit.

Why Use a Free Rightmove Property Analyser Instead of a Spreadsheet?

Most UK property investors still use spreadsheets — entering asking prices, estimated rents and mortgage rates by hand. That takes 20–30 minutes per property and is easy to get wrong. DealFlow AI does the same calculation in under 60 seconds by reading the Rightmove listing directly, so you can check 10 deals in the time it takes to manually analyse one.

The free Rightmove analyser also pulls in data you'd normally have to look up separately: the EPC certificate, planning history and comparable rental rates. Everything is shown on one screen, with a plain-English verdict at the top.

What Does a Good Rightmove Deal Look Like?

When analysing Rightmove properties for buy-to-let investment, the numbers to focus on are:

✓Gross yield above 6% — the minimum threshold for a deal to stack up after all costs in most UK locations.
✓Positive monthly cash flow — rent should comfortably cover mortgage, agent fees (~10%), maintenance (~1% per year) and void periods (~4 weeks/year).
✓EPC rating D or above — the minimum to legally let a property in England and Wales is E; proposed legislation may raise this to C.
✓Asking price at or below market value — DealFlow AI flags properties priced above comparable sales in the same street.
