Buy-to-let, without the manual overhead.
For portfolio landlords, limited companies, HMOs, and MUFBs.
Buy-to-let is where portfolio complexity meets stress testing, ICR calculations, and corporate structures. Mast handles the data model, the policy, and the workflow so your underwriters can focus on judgement, not spreadsheets.
The friction buy-to-let lending inherits.
Portfolios spread across spreadsheets and PDFs
ICR and stress tests that vary by product and tenure
Limited-company structures with multiple directors and shareholders
HMO and MUFB cases treated as bespoke every time

HMO and MUFB support
Property-type specific fields, valuations, and policy without forcing bespoke workflows for every case.

Portfolio and company cases handled through the same journey as vanilla BTL.
Update ICR or stress logic in minutes when market conditions change.
