Private investors Keystone mortgages are suitable for first-time landlords and experienced landlords including those with large property portfolios who may have found it hard to get a buy to let mortgage with mainstream lenders.
Corporate investors We understand that some investors find it tax efficient to operate via a corporate entity so we are happy to accept applications from SPVs, LLPs and trading limited companies.
HMOs We have rates designed specifically for licensed Houses in Multiple Occupation and multi-lets that do not need licensing including student houses, bedsits and professionals sharing a house or flat.
Blocks of flats We have mortgages designed to cater for multi-unti blocks owned on a single freehold, typically purpose built blocks of flats and period houses converted into flats.
Renovations & new builds Unlike most lenders, in addition to new build properties we'll consider recently refurbished properties that need remortgaging within six months of purchase.
Flexible lending terms We offer up to 80% LTV on some products. And we can lend up to £1m to 70% LTV. All arrangement fees are added to the loan. We'll also consider corporate leases up to 5 years (on a FRI basis).
Fast processing All applications are thoroughly pre-checked by a senior underwriter before proceeding to reduce unnecessary requests for information. Using title indemnity insurance for remortgages actively reduces turnaround times.
