Sourcing across Limited company & SPV Portfolio landlords HMO & MUFB Semi-commercial Commercial
Built for the specialist end

The cases the big sourcing systems can't handle.

Mainstream tools stop at vanilla buy-to-let. DAS Source is built for limited-company portfolio landlords and the semi-commercial and commercial deals that need real underwriting logic.

Maximum lending, ranked

See exactly how much each lender will advance on the deal — 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.

Semi-commercial & commercial

Specialist lenders the residential systems ignore — with the right rent-cover and DSCR logic for mixed-use and commercial investment.

Your branding, front and centre

Your logo, your colours, your contact details. Clients see your firm — the engine runs quietly behind it.

Client-ready output

Export a clean, branded comparison to Excel or PDF, or share a live link — ready to send straight to your client.

Always current

Rates kept up to date across the specialist panel, with the “as of” date shown on every illustration.

The panel

The lenders your clients actually need.

A specialist panel focused on limited-company, portfolio, semi-commercial and commercial lending — with more added regularly.
