Frequently asked questions
What are MUFBs?
MUFBs are multi-unit freehold blocks, meaning multiple self-contained flats held under a single freehold title, commonly financed using specialist buy-to-let or commercial mortgage products.
Can a first-time buyer get an MUFB mortgage?
Yes, first-time buyers can obtain MUFB mortgages, but lender options are more limited and borrowing is often capped at lower LTVs, with stricter affordability and property criteria applied.
How are MUFBs valued?
MUFBs are valued either as a single block investment, often based on rent and investor demand, or on the aggregate of the individual flats' values. The block basis is usually lower because fewer buyers can purchase a whole block.
What LTV are MUFB mortgages?
MUFB mortgages commonly offer loan-to-value ratios between 65% and 85%, depending on unit count, valuation approach, shared utilities, tenancy profile, and whether the block qualifies for buy-to-let rather than commercial lending.
What is an MUFB bridging loan?
An MUFB bridging loan is a short-term loan secured on a multi-unit freehold block, used to buy, refurbish or refinance it before an MUFB mortgage, a title split refinance or unit sales repay it.
