Why it works
Why to be cautious
- Monthly profit −£14,489/mo — heavily negative — needs monthly capital injection
- -19.5% 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.
- EPC band not stated — verify the certificate before offering (2030 MEES minimum is band C).
