Commercial is valued on income, not £/ft² comps — so this weapon speaks both languages. Investment mode works the yield: NIY, reversion, WAULT, and the price that hits your target. Conversion mode works the Class MA play: can it go resi without full planning, how many flats fit, what the works cost, and the maximum offer that still leaves your profit in. Free, instant, every assumption adjustable — then send it to the Commercial X-Ray for live end-unit values.
Designations — the Class MA gate
Enter a postcode — signed-in hunters get designations checked automatically; otherwise set what you know:
An appraisal screen, not an RICS valuation, tax advice or a planning decision. Non-residential SDLT bands shown are England & NI — Wales (LTT) and Scotland (LBTT) differ. Class MA rules are as amended March 2024 and change often — a Lawful Development Certificate or pre-app from the council is the only real answer. Commercial leases live and die on the actual lease documents and the tenant's filed accounts — read both before any offer.
