First Charge Mortgage

A First Charge Buy-to-Let Mortgage is the main loan secured against your rental property. The lender holds the first legal claim on the property if repayments aren’t met. These products are ideal for purchasing BTL properties or remortgaging an existing one to secure a better rate or release equity.

Benefits

  • Grow your portfolio: Purchase new properties or refinance existing ones.
  • Competitive rates: Access specialist BTL lenders offering competitive first-charge products.
  • Rental income potential: In most cases, rental income can cover the mortgage payments.
  • Long-term investment: Your property may increase in value over time, helping build wealth for the future.

Second-charge mortgages

A Second Charge BTL Mortgage is secured against the equity in an existing property without disturbing your current first-charge mortgage. These can be useful if you need additional funds but want to keep your current rate or avoid early repayment charges.

We offer:

  • Self-funding and non-self-funding options
  • Options over 100% loan-to-value in some circumstances
  • Solutions for borrowers with historic or current credit issues
  • Products that may not require consent from the first-charge lender

If one property doesn’t provide enough equity, you can secure the loan across multiple buy-to-let properties or use a second charge on your residential home to raise the deposit you need.

Benefits

  • Access additional funds: Ideal for deposits, refurbishments, consolidating BTL debts, or expanding your portfolio.
  • Protect your main mortgage: Keep your existing first charge and interest rate.
  • Flexible underwriting: Options available even with complex income or less-than-perfect credit.

Bridging Finance available

If you need to purchase quickly — for example, at auction or before another buyer steps in — we may be able to arrange short-term bridging finance to secure the property.
