What Does Remortgaging a Buy to Let Property Mean?

Remortgaging a buy to let property involves switching your existing buy-to-let mortgage to a new deal, either with your current lender or a new one. The aim is usually to secure better terms, such as a lower interest rate, or to borrow additional funds using the property’s equity.

Unlike residential remortgaging, buy-to-let remortgages focus heavily on the property’s rental income rather than your personal income. Lenders assess whether the rent comfortably covers the mortgage payments, usually through stress testing.

When remortgaging buy to let property, you may also choose between interest-only or repayment mortgage options, depending on your strategy.

Why Do Landlords Remortgage Buy to Let Property?

Securing a Better Interest Rate – Many landlords remortgage when their fixed-rate deal ends and they move onto a lender’s higher standard variable rate. Switching to a new deal can help reduce costs and improve monthly profitability.

Releasing Equity for Further Investment – As property values rise and mortgages are paid down, equity builds up. Remortgaging allows landlords to release some of this equity to fund additional property purchases or improvements.

Switching Mortgage Type – Some landlords choose to switch between interest-only and repayment mortgages when remortgaging, depending on whether their priority is cash flow or long-term debt reduction.

Portfolio Restructuring – For landlords with multiple properties, remortgaging can help simplify finances, manage risk, or rebalance borrowing across a portfolio.

Improving Cash Flow – Lower monthly payments can improve rental yield and provide more flexibility to cover maintenance costs or unexpected expenses.

When Is the Right Time to Remortgage a Buy to Let?

Timing is important when remortgaging buy to let property. Common times to review your options include:

  • When your fixed-rate deal is ending
  • Around 3–6 months before your current mortgage expires
  • When interest rates change
  • After an increase in rental income
  • Following a rise in property value

At Rosa Mortgages, we’ll help you assess whether now is the right time or whether waiting could be more beneficial.

How Much Can You Borrow When Remortgaging Buy to Let?

The amount you can borrow depends on several factors, including:

  • The current value of the property
  • The outstanding mortgage balance
  • The lender’s Loan-to-Value (LTV) limits
  • The property’s rental income and stress testing
  • Whether the property is owned personally or through a limited company

Most lenders cap buy-to-let remortgages at 75–80% LTV, though this can vary. Rental income must typically cover 125–145% of the mortgage payment at a stressed interest rate.

We’ll calculate how much equity you may be able to release and ensure any additional borrowing is affordable and aligned with your investment plans.

Can You Remortgage a Buy to Let with Bad Credit?

It may still be possible to remortgage a buy to let property with past credit issues, depending on the circumstances. Some specialist lenders will consider applications with:

  • Older missed payments
  • Satisfied defaults
  • CCJs
  • Previous debt management plans

Lenders look at the overall strength of the case, including rental income, equity, and how long ago the credit issues occurred. At Rosa Mortgages, we’ll assess your situation honestly and guide you towards lenders most likely to support your application.

When remortgaging buy to let property, it’s important to factor in potential costs, including:

  • Early repayment charges (ERCs) on your current mortgage
  • Valuation fees
  • Legal fees
  • Arrangement fees charged by the new lender
  • Broker fees, where applicable
