Keystone Property Finance has announced the launch of its new special-edition House in Multiple Occupation (HMO) and Multi-Unit Freehold Block (MUFB) products, aimed at simplifying the buy-to-let (BTL) mortgage market for landlords. This new range offers a competitive pricing structure, making it an attractive option for both new and existing property investors.

What are the key features of the new products?

The newly introduced HMO and MUFB products come with a reduction compared to Keystone’s core range. This reduction is significant for landlords managing small and large HMOs. Additionally, Keystone has streamlined its fee structure, offering clear options across its various mortgage ranges, including standard, specialist, expat, and holiday let categories.

How does this impact the mortgage market for landlords?

The introduction of these competitively priced products is expected to enhance competition within the buy-to-let mortgage market. Landlords can benefit from lower borrowing costs, which can improve their overall investment returns. This move may also encourage more landlords to consider expanding their portfolios, particularly in the HMO and MUFB sectors, which have seen increased demand due to the ongoing housing shortage.

What this means for property investors

For property investors, the launch of Keystone’s special-edition products represents an opportunity to access more affordable financing options. With rates starting lower than previous offerings, investors can potentially increase their cash flow and profitability. As the market adapts to these changes, it will be essential for investors to stay informed about evolving mortgage options and market trends.
