The lender has increased its definition of small HMOs from up to 6 to 8 bedrooms and large HMOs from 9 to 15 bedrooms.
The maximum loan size for both large HMOs and MUFBs has increased to £3,000,000, with the definition of a MUFB changing from up to six units, to up to 10 units.
A large loan range has also been introduced for standard properties and small HMOs, with products available for up to £2m at a maximum of 70% LTV.
BTL customers will also receive a £500 cashback contribution towards legal fees when they take out a five-year fixed buy-to-let mortgage for standard property types on products up to 75% LTV.
Ian Boden, sales director at LendInvest, commented: “After a fantastic 2019 for our buy-to-let product, we are excited to be hitting the ground running this year with a broadening of our product criteria.
"Ever eager to increase the flexibility of our product, we are confident these changes will put us in good stead for a busy 2020; and look forward to further increasing our loan volumes in the coming months.”
