Landlords may remortgage to secure a new rate, release equity or restructure their property portfolio.

The lowest advertised rate will not necessarily provide the best overall outcome. Early repayment charges, product fees, legal costs and rental stress tests should all be considered.

At MortgageKey, our specialist buy-to-let advisers can review your existing mortgage and compare remortgage and product-transfer options from a range of lenders.

What you need to know

What is a buy-to-let remortgage?

A buy-to-let remortgage involves moving the mortgage on a rental property to a new lender or replacing it with a different arrangement.

The new mortgage repays the existing lender and is then secured against the property.

You may keep the mortgage balance broadly the same or apply to borrow more. Any additional borrowing will be subject to the property value, expected rent, lender criteria and the purpose for which the money will be used.

Why remortgage a buy-to-let property?

Landlords may consider remortgaging to:

  • Obtain a new interest rate
  • Avoid moving onto a standard variable rate
  • Reduce monthly mortgage payments
  • Release equity from the property
  • Fund the deposit on another investment
  • Pay for renovations or repairs
  • Change the mortgage term
  • Move between interest-only and repayment
  • Transfer to a lender with more suitable criteria
  • Refinance short-term or bridging finance
  • Restructure a property portfolio

Whether remortgaging is worthwhile will depend on the total cost and your longer-term investment plans.

When should I review my buy-to-let mortgage?

It can be helpful to review your options several months before your current mortgage deal ends.

Starting early provides time to:

  • Compare products
  • Check early repayment charges
  • Obtain rental evidence
  • Resolve property or title issues
  • Complete the valuation
  • Prepare company or portfolio documents
  • Secure a product before the existing deal ends

Some mortgage offers remain valid for several months, although the exact validity period varies between lenders.

If your existing deal has already ended, reviewing the mortgage promptly could reduce the time spent on your lender’s standard variable rate.

Why choose MortgageKey for a buy-to-let remortgage?

Buy-to-let lenders use different rental calculations, property criteria and portfolio rules.

MortgageKey can help you:

  • Review your current mortgage
  • Compare remortgage and product-transfer options
  • Calculate the cost of early repayment charges
  • Assess the property’s rental coverage
  • Explore equity-release options
  • Compare personal and limited company products
  • Assist with portfolio landlord applications
  • Review specialist HMO and MUFB mortgages
  • Support the application through to completion

Any recommendation will consider the rate, fees, mortgage term and total cost.

Frequently asked questions about buy-to-let remortgages

How early can I apply for a buy-to-let remortgage?

You can normally begin reviewing options several months before your current deal ends. The right timing depends on your early repayment charge and the validity period of the new mortgage offer.

Can I remortgage without increasing the loan?

Yes. A like-for-like remortgage replaces the existing balance without significant additional borrowing, although fees added to the loan could cause a small increase.

Do I need a tenant before remortgaging?

Not always. Some lenders accept vacant properties based on the valuer’s expected market rent. Others require an acceptable tenancy to be in place.

Can I remortgage more than one property at once?

Yes. Portfolio landlords can remortgage several properties, although each property and the overall portfolio will be assessed.

Can I remortgage if my property has fallen in value?

It may still be possible if there is enough equity and the loan meets the lender’s maximum loan-to-value. A lower value could reduce the available products or prevent additional borrowing.

Is a product transfer always quicker than remortgaging?

It is often simpler because the mortgage stays with the existing lender, but processing times and eligibility vary. It should still be compared with other available options.

Important information

Your property may be repossessed if you do not keep up repayments on your mortgage.

Tax treatment depends on individual circumstances and may change. MortgageKey does not provide tax or legal advice. You should obtain specialist advice where appropriate.
