7.24% Rent by the room return before costs — market rent unverified, verify rent + comps locally.
Why it works
Why to be cautious
Monthly profit −£421/mo — significantly negative — real recurring drain
-3.7% 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).

Potential, not guaranteed (subject to planning + regs). Estimate from the floorplan (kitchen size assumed) — verify room sizes against the floorplan before offering.
How we calculated this
floorplan shows 5 habitable rooms (3 beds + 2 reception(s)) in 80 m²; convert 1 spare room(s) to bedrooms, keeping one reception as the lounge → up to 4 lettable rooms; sized to Buckinghamshire adopted standard (8/13 m²; Standards for Houses in Multiple Occupation, Buckinghamshire Council (web standards; PDF April 2020)); adds ~£804/mo; loft conversion may add 1-2 further rooms (subject to head height/planning — not counted)
Pro members see the floorplan with every convertible room outlined in green. Verify room sizes before offering.
3 → 4 bed HMOuplift 5.26% → 5.21%
Projections use documented assumptions (local room rates, typical conversion costs, 75% LTV at 5.5%, indicative regional valuation yields) and each council’s published HMO standards. Not financial advice. Verify room sizes, licensing and planning with the council and a surveyor before purchase.
