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 79 m²; convert 1 spare room(s) to bedrooms, keeping one reception as the lounge → up to 4 lettable rooms; sized to Swansea adopted standard (6.5/10.2 m²; Swansea HMO Licensing Policy 2020 App.A Amenity Standards); adds ~£534/mo; loft conversion may add 1-2 further rooms (subject to head height/planning — not counted); Rent Smart Wales registration required; check council additional-licensing scheme; Wales: planning permission required for HMO change of use (no C3→C4 permitted development)
Pro members see the floorplan with every convertible room outlined in green. Verify room sizes before offering.

Wales: planning required for HMO use
✓Sized to Swansea'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.
