Buy-to-Let Mortgages for Landlords & Investors


Your Ideal Investment Mortgage, Sourced from Hundreds of Lenders


At Willow Private Finance, we make financing your buy-to-let property clear, efficient, and tailored to your portfolio goals.

As an FCA regulated Mortgage Specialist, we’re not just here to secure your buy-to-let mortgage—we give you access to lender options you won’t normally find on the high street.


Our direct relationships often mean sharper rates, more flexible terms, and a streamlined process designed for landlords and investors who want their property finance handled properly.

At Willow Private Finance, we’ve been helping landlords and property investors build and refinance buy-to-let (BTL) portfolios since 2008. 


Whether you’re acquiring your first rental, restructuring to improve cash flow, or scaling into HMOs, MUFBs or limited-company/SPV structures, our approach is personal, proactive and results-oriented. 


We navigate lender criteria, stress rates and evolving regulation—from interest-only options to portfolio underwriting and EPC/“green” considerations—so your finance aligns with yield, tax efficiency and long-term growth. UK-based, expat or investing from overseas, we simplify the process and deliver tailored funding that moves your strategy forward.
