Loading the live panel…
Live products from the DAS Source panel, priced in your browser. Illustration only — DAS Source is for FCA-authorised intermediaries, and every result must be verified against the lender's current criteria before advising a client.
The cases the big sourcing systems can't handle.
A sourcing system built around semi-commercial and commercial deals — and the limited-company portfolio landlords the mainstream tools were never designed for.
Maximum lending, ranked
How much each lender will actually advance — biggest first, with the rental surplus left after payment. The question portfolio landlords actually ask.
Ltd Co & ICR done right
Company vs personal stress rules, gross-LTV caps, HMO and MUFB cover ratios — the calculations mainstream tools get wrong, handled to the penny.
Mixed-use & commercial
Specialist lenders the residential systems ignore, with the right rent-cover and DSCR logic.
Client-ready output
Export a clean comparison to Excel or PDF, ready to send straight to your client with your name on it.
Always current
Rates maintained across the specialist panel, with the “as of” date shown on every illustration.
Every product, not a shortlist
2,600+ live products are priced against the case — not a curated handful — so the answer is the market, not a sample of it.
Not a shortlist. A case, priced and packaged.
This is the real output, running on the live panel — the same detail a broker gets inside DAS Source, on a 13-unit MUFB remortgage for a portfolio landlord.
Remortgage · MUFB (13 units) · property value £500,000 · expected rent £4,500 pcm · portfolio landlord: 15+ properties
