Question 1

What is a good rental yield in the UK?

Accepted Answer

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.

Question 2

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

Accepted Answer

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.

Question 3

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

Accepted Answer

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.

Question 4

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

Accepted Answer

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.

Question 5

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

Accepted Answer

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.
