## Buy to let mortgage for two flats on one title

A buy to let mortgage for two flats on one title applies where two separate, self-contained flats are held under a single freehold title rather than on individual leases. Although each flat may operate independently, the shared title means lenders assess the property as a single investment asset rather than two separate dwellings. For this reason, these cases are commonly assessed in a similar way to small multi-unit freehold blocks.

### Why lenders care

Lenders focus on liquidity and exit strategy. Where two flats sit on one title, resale is typically restricted to investors rather than owner-occupiers, as the units cannot usually be sold separately without legal restructuring. This narrower buyer market increases exit risk.

### What lenders typically look for

Lenders usually expect each flat to be clearly defined and fully self-contained, with independent kitchens, bathrooms, and access. Valuation methodology is critical, with the valuer confirming whether the property is assessed as a single block or on an aggregate basis. Legal clarity around occupation and services also supports mortgage ability.

### Buy to let considerations

From a buy to let perspective, two flats on one title are often treated similarly to MUFB lending rather than standard single-unit buy to let. Lenders place greater emphasis on long-term rental stability and resale certainty when assessing this structure.
