Questions brokers ask
Who are DAS Source broker tools for?
FCA-authorised mortgage intermediaries, especially brokers placing specialist buy-to-let, limited company, HMO, multi-unit and semi-commercial cases. DAS Source is not intended for consumers.
Which tools are free?
The limited company stamp duty calculator and the buy-to-let ICR calculator are free to use without an account. The property check and company check are included with a DAS Source subscription, which starts with a 7-day free trial.
Where does the data come from?
Public registers: HM Land Registry price paid data, the EPC register, Companies House, Environment Agency flood warning areas, council licensing schemes and Article 4 directions from planning.data.gov.uk.
Are the results advice?
No. The tools draw on public registers and are provided for reference. Stamp duty figures are estimates, flood results are an indicator rather than a flood search, and lender criteria must be checked before advising a client.
