* Rent by the room shows net yield on cost for the audited HMO conversion deal (post-conversion, after running costs) — not gross like the other rows. Its 5-yr ROI reads “—” because the audited deal is a year-one snapshot; the HMO conversion panel below shows the cash-back / payback horizon.

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 6 habitable rooms (3 beds + 3 reception(s)) in 60 m²; convert 1 spare room(s) to bedrooms, keeping one reception as the lounge → up to 4 lettable rooms (2 double, 0 single); sized to Richmond upon Thames adopted standard (6.51/10.22 m²; Minimum Amenities Standards for Houses in Multiple Occupation 2020 (11/11/2020)); kitchen 6.3 m² is below the ~7.0 m² standard for 4 occupants — extend/relocate kitchen within the works; adds ~£829/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 Richmond upon Thames'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.
