Weak
6.51% return before costs — market rent unverified, verify rent + comps locally.
Why it works
- Priced below market -16% vs 12 nearby sold (last 12 mo) — instant equity
- Long lease (990 yrs) — no short-lease drag
- EPC B — MEES compliant
Why to be cautious
- Monthly profit −£388/mo — significantly negative — real recurring drain
- -2.3% 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.
