6.16% Rent by the room return before costs — market rent unverified, verify rent + comps locally.
Why it works
Why to be cautious
Monthly profit −£422/mo — significantly negative — real recurring drain
-3.4% 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)); convert 1 spare room(s) to bedrooms, keeping one reception as the lounge → up to 4 lettable rooms (0 double, 1 single); sized to Slough adopted standard (6.51/10.22 m²; Houses in Multiple Occupation — Standards in Licensable Properties (Slough BC)); kitchen 6.9 m² is below the ~7.0 m² standard for 4 occupants — extend/relocate kitchen within the works; adds ~£727/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.

✓Sized to Slough's adopted HMO standards
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.
