Why it works

Nothing here counts in its favour
No figure on this listing stands out in the property’s favour. That is a finding, not a gap — the cautions opposite are what this deal turns on.

Why to be cautious

No EPC band on record — the rating decides whether you may legally rent it out
An F or G rating has made a property unlettable on new tenancies since April 2020, and every rent figure on this page assumes it can be let.Free to check on the government EPC register in under a minute — do it before you offer, not after.
Article 4 in area — Rent by the room conversion needs planning permission
The council has removed the automatic right to convert to a shared house here — it needs planning permission.It does not affect letting the property normally, and permission is often granted. It is a step, not a wall. See who decides →
Monthly profit −£382/mo — a real cost you carry every month you hold it
You would be topping it up every month, from your own income, for as long as you hold it.That can still be the plan if you are buying for capital growth — but it should be a decision, not a surprise. Try your own numbers →
No rent comparables — estimate is a rule-of-thumb fallback, not market data. Verify the rent locally before offering.

What would have to be true?
No recorded basis for the rent to work from
Every price on this card is that rent inverted, and this row records no basis for its rent — not that the rent is wrong, but that we cannot show it was measured against nearby lettings. A price quoted to the £5,000 needs evidence we can point at.
