Weak
4.01% return before costs — market rent unverified, verify rent + comps locally.
Why it works
- EPC B — MEES compliant
Why to be cautious
- Monthly profit −£1,317/mo — heavily negative — needs monthly capital injection
- -6.3% 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).
