Buy to let refinance is where most landlords' money is either made or quietly lost. The purchase gets the attention; the refinance three years later decides what the property actually returns.
Whether you are coming off an expiring fixed rate, releasing equity to fund the next deposit, or moving a property off a bridging loan onto term finance, the structure matters more than the headline rate.
When Landlords Refinance
- An expiring fixed rate. Reverting to a lender's standard variable rate is usually the single most expensive thing a landlord can do by inaction. Start six months out, not six weeks.
- Releasing equity for the next purchase. Capital raising against a property that has grown in value, to fund the deposit on the next one. This is how most portfolios are built.
- Exiting a bridging loan. A property bought at auction or refurbished on a bridging loan needs a term exit. Lenders will want to see the works completed, the property let or lettable, and in many cases a minimum ownership period.
- After refurbishment. Refinancing on the improved value rather than the purchase price is what recycles your capital out of the deal.
- Restructuring a portfolio. Moving between lenders, consolidating onto a portfolio facility, or changing ownership structure.
How Buy To Let Lending Is Assessed
Buy to let is assessed primarily on the rent, not your salary. Lenders apply an interest cover ratio — the rent must exceed the mortgage interest by a set margin, tested at a stressed rate rather than the rate you are paying.
Two things follow from that. First, the rental valuation carries enormous weight, and a conservative surveyor's figure can reduce what you can borrow. Second, a five-year fixed rate is often stress-tested more generously than a two-year, which is why a longer fix sometimes permits a materially larger loan.
Personal-name and limited company applications are stress-tested differently, and higher-rate taxpayers frequently find the company route works better after tax. That is a decision to take with your accountant — we will tell you what each structure allows you to borrow, and they should tell you what each one costs you in tax.
Limited Company and SPV Refinance
Most new landlord borrowing now goes through limited companies, typically an SPV set up for the purpose. Lender choice is narrower than the personal-name market but no longer specialist, and personal guarantees from directors are standard.
Moving an existing personally-held property into a company is a sale and repurchase, not a transfer — with the stamp duty and potential capital gains that implies. Take advice before assuming it is worth doing.
Portfolio Landlords
At four or more mortgaged buy to let properties, you are a portfolio landlord under PRA rules and the assessment changes. Lenders will review the whole portfolio, not just the property being refinanced — schedules, background rental stress testing, and often business plans and cash flow forecasts. A single weak property can affect an application on a strong one.
Refinancing With Adverse Credit
Buy to let refinance with credit issues is workable more often than landlords expect, particularly where the rental income is strong and the loan to value is modest. Where the credit profile is the obstacle, our bad credit mortgages page covers what specialist lenders will consider.
Frequently Asked Questions
How soon can I refinance after buying?
Many lenders apply a six-month rule before they will lend on the current value rather than the purchase price, though a number of specialist lenders will consider day-one refinance where value has been added through works.
How much equity can I release?
Typically up to 75% loan to value, subject to the rental income covering the stressed payment.
Can I refinance a property that is currently empty?
Usually yes, on the basis of the achievable market rent, though some lenders will require a tenancy in place.
Does bad credit rule out a buy to let remortgage?
No. Specialist lenders assess adverse credit on how recent and how serious it is, alongside the rental cover and the loan to value.
Your property may be repossessed if you do not keep up repayments on any loan secured against it. Most buy to let mortgages are not regulated by the Financial Conduct Authority.
