4 → 7 lettable rooms · ~7.4% gross at max
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 8 habitable rooms (4 beds + 4 reception(s)) in 104 m²; convert 3 spare room(s) to bedrooms, keeping one reception as the lounge → up to 7 lettable rooms (1 double, 2 single) (incl. the garage — convertible to a bedroom or the communal area); sized to Sunderland adopted standard (6.51/10.22 m²; Guidance for Landlords on HMO Standards in Sunderland (c.2021)); kitchen 10.9 m² is below the ~11.0 m² standard for 7 occupants — extend/relocate kitchen within the works; adds ~£1,518/mo; loft conversion may add 1-2 further rooms (subject to head height/planning — not counted); large HMO (7+ residents) is sui generis — planning permission required; mandatory HMO licence (5+ persons, England)
Pro members see the floorplan with every convertible room outlined in green. Verify room sizes before offering.
4 → 7 bed HMOuplift 8.25% → 7.44%
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.
