Weak
4.47% return before costs — market rent unverified, verify rent + comps locally.
Why it works
- Long lease (977 yrs) — no short-lease drag
Why to be cautious
- Monthly profit −£3,904/mo — heavily negative — needs monthly capital injection
- -9.3% 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.
- EPC band not stated — verify the certificate before offering (2030 MEES minimum is band C).
