Buy to let mortgage for two flats on one title

Yes. Buy to let mortgages for two flats on one title are available but are typically assessed as a single investment asset. Lenders focus on unit separation, valuation approach, and resale demand, often treating the property similarly to a small block.

Banks and building societies test the rent against the interest at a stressed rate under the Prudential Regulation Authority's underwriting standards (PRA: SS13/16), and other lenders set their own tests. Some lenders also look at personal income, for a minimum income rule or to support the rent, and some want two years of self-employed figures where they read that income at all.
