Best Buy to Let Remortgage Rates UK: How One Landlord Avoided the SVR Trap

Customer Overview

This case study involves a landlord in his mid-40s working in a professional services role based in the South of England. He owns a buy-to-let property and recently approached us for help finding suitable buy-to-let remortgage rates as his current mortgage fixed rate was due to expire within just days.

The Problem: Imminent Fixed Rate Expiry and Limited Time to Act

With only 8 days before his current buy-to-let fixed-rate mortgage ended, this client faced an urgent decision: either secure a new mortgage deal or lapse onto a significantly higher Standard Variable Rate (SVR). He preferred a 2-year fixed rate without extending the loan term, wanted to retain his monthly rental income margins, and was cautious about locking into a higher long-term rate.

Making the situation more complex was the client’s credit history, which limited options with mainstream lenders and ruled out switching to a new provider within the remaining timeline. Delaying would result in losing income through higher monthly payments.

The Solution: A Timely Rate Switch with Existing Lender

Understanding the urgency and credit profile challenges, we sourced the best buy-to-let remortgage rate in the UK available through a rate switch with the client’s existing lender, Birmingham Midshires (Halifax PLC).

Key Mortgage Features Secured:

• Term: 20 years and 1 month (unchanged)
• Type: Interest Only
• Rate: 3.28% fixed until January 2028
• Monthly Payment: £734.37 (Initial Period)
• Repayment Vehicle: Sale of property

By opting for this route, the client locked in a competitive rate swiftly without slipping onto a high SVR or resorting to more expensive subprime lending. The product included a fee (added to the mortgage), chosen to reduce monthly outlay and improve cash flow from rental income, ensuring the remortgage process was smooth.

Why This Product Was Chosen:

• Fast execution to avoid the SVR
• Better short-term value compared to 5-year options
• No tie-in after rate period expiry
• Add-on valuation and admin cost benefits

Results: Preserved Rental Margins and Avoided Rate Hike

The outcome was successful on several fronts:

• The client avoided the SVR increase (potentially over £1,900 in monthly payments)
• Maintained a monthly mortgage cost of just £734.37
• Kept mortgage term and repayment strategy intact
• Gained flexibility to reassess the market in 2 years without the pressure of high buy-to-let remortgage rates.

“This fix was not just about the lowest rate – it was about securing stability and flexibility at the right time. You saved my rental income from taking a hit — and that was crucial.”

Frequently Asked Questions (FAQs)

Can you remortgage a buy-to-let to avoid a high SVR?

Yes, especially if you’re eligible for a rate switch with your current lender. It’s quicker than remortgaging with a new lender and can help you avoid the higher monthly payments associated with SVRs.

What happens if my buy-to-let mortgage rate expires?

If no action is taken, you’ll typically revert to the lender’s standard variable rate — often much higher than fixed-period rates. This can significantly raise your monthly repayments.

What documents are needed for a rate switch?

Usually fewer documents are required compared to a full remortgage. However, you may still be asked for proof of identity, address, income, and rental agreements depending on the lender.

Are buy-to-let mortgages affected by my credit score?

Yes. If your credit profile is weak, you may have fewer options or need to work with a specialist lender. In some cases, a rate switch with your current lender may be the best route.

Can fees be added to the mortgage?

Yes, many lenders allow you to add product and admin fees to the mortgage loan. This can ease upfront costs but will increase the total amount of interest paid over time.
