The specialist sourcing engine, branded as yours.
DAS Source compares the whole specialist market — limited-company BTL, portfolio, semi-commercial and commercial — in seconds. Your logo, your clients, our engine behind it.
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 lenders your clients actually need.
A specialist panel focused on limited-company, portfolio, semi-commercial and commercial lending — with more added regularly.
