5.95% Rent by the room return before costs — market rent unverified, verify rent + comps locally.
Why it works
Why to be cautious
- EPC D — must hit C by 2030 (~£3,000–£7,000)
- Monthly profit −£667/mo — heavily negative — needs monthly capital injection
- -5.1% 5y IRR — capital outlay disproportionate to returns
- No rent comparables — estimate is a rule-of-thumb fallback, not market data. Verify the rent locally before offering.

How we define each return: On price — gross yield = annual rent ÷ purchase price. On cost — net yield ÷ total project cost (price + refurb + fees). On cash — cash-on-cash & ROI ÷ the actual cash you put in (deposit + costs).
