Can You Remortgage to Buy Another Property?
It’s possible to remortgage to release equity so you can buy another property as long as you meet the remortgage criteria set by the lender. You’ll also need to ensure that refinancing your current property will raise enough funds to put down a deposit on the new property or purchase it outright. Mortgage lenders will want to make sure that you can afford to pay your new refinanced mortgage alongside any lending secured against the new property.
What Property Can You Buy When Remortgaging Your House?
There are many reasons why you might remortgage to release equity so you can buy a second property.
For example:
Remortgage to Get a Buy to Let
A buy-to-let mortgage is a popular way for people to build a property portfolio and get a return on their investment by letting the property to tenants. You can also opt to move into the new property and rent out your original house, switching the mortgage on your existing property onto a buy-to-let basis via a process called let to buy. Meanwhile, a holiday let mortgage lets you buy property for short-term lettings. You can fund all these types of rental investments through remortgaging your main property and releasing equity.
Remortgage to Buy Second Property
You may want to buy a second home because you need a place in the city to avoid the hectic daily commute. Alternatively, it could be that you want a family holiday home or to be able to support your retired parents. You can finance a second property by remortgaging your main property and releasing equity to use as a deposit.
Remortgage to Buy Commercial Property for Your Business
If you want to expand your business by investing in commercial property to use as offices or warehouse space for your company, you can remortgage your primary property to raise the funds you need.
How Does Remortgaging Work to Buy Another Property?

Remortgaging your home to buy another property works similarly to a normal remortgage, with the main difference being that you remortgage for more than the amount outstanding on your existing mortgage. This allows you to release equity which can then be used as a deposit for the new property or, in some cases, you could purchase it outright without a mortgage.
When you remortgage your home, the lender will assess various factors, such as your affordability, equity, income, LTV (loan to value), debts and credit rating. It’s also important to understand that the lender will want to know why you want to remortgage. They will ask questions like: are you buying a second home or a rental property? are you planning to use the funds for a deposit or will you buy outright? Clarifying these details can help lenders understand your specific situation.

What if I Want to Remortgage My House on to Buy to Let and Buy Another?
The process for remortgaging to buy another property differs slightly when it comes to let to buy — i.e. when you remortgage your existing home on to a buy to let mortgage, while also using the additional funds to purchase a new main residence.
With let to buy, you’ll be remortgaging with a buy to let lender who won’t focus solely on your personal affordability but will instead consider the potential rental income the buy to let property could generate. This is an important factor in determining whether you qualify for the loan.
Remortgaging Your House to Buy Another Property Fees and Costs
Remortgaging your house to buy another property will incur certain fees and costs, for example:
- Stamp Duty: you pay Stamp Duty when you buy a property in the UK. Buying a second home or buy to let currently requires an additional 3% of Stamp Duty on top of the standard rates for a main residence
- Mortgage fees: buy to let mortgages often have higher interest rate costs than residential mortgages. You may also have to pay ERCs if you remortgage before your introductory deal period ends and you may face administration costs
- Other rental fees: if you’re planning on renting out your second property after you've remortgaged, there may be additional fees such as the cost of estate agents
How Many Mortgages Will I Have When Remortgaging to Buy Another Property?
You may be fortunate and find that remortgaging your first property provides enough funds to cover your outstanding mortgage while releasing enough equity to purchase a second property outright. However, it's more likely that this won’t be the case, and instead, you'll use the additional released equity from the first property to fund a deposit for the new property, leaving you with 2 mortgages. These mortgages will most likely be with different lenders and will be completely separate products. They could both be residential mortgages, or one could be buy to let while the other remains residential.
What Should You Consider Before Remortgaging to Buy Another Property?
If you’re considering remortgaging your home to buy another property, you should take the following into account:
- The property type and what you want to use it for
- How much equity you have in your primary property
- Your circumstances, including your affordability and credit history
Type of Property
The type of property you intend to buy after remortgaging will determine the mortgage products you qualify for.
For example:
- Buy to let: this is a rental property that you let out to tenants. The money you raise from remortgaging your home could be used as a deposit for a buy to let mortgage on a new property
- Let to buy: this is where you remortgage your current residence onto a buy to let basis, allowing you to rent it out to tenants while releasing equity to use as a deposit on a second property for yourself to live in
- Holiday lets: you purchase a property to rent out for short term holiday rentals or breaks.
- Second homes and holiday homes: you use the money raised from remortgaging to buy another property to use in addition to your primary home, but not as your main residence
- Commercial property: you remortgage your primary property to raise funds to buy a property for your business, such as an office or shop. If you already own a commercial property, you can refinance this to purchase another property
Some mortgage lenders are also interested in the property's build type and prefer to approve loans on properties considered standard construction, such as those made from bricks and mortar. However, some mortgage lenders specialise in more unusual buildings, which may be useful to you if your new property is of non-standard construction. Specialist, independent mortgage brokers like John Charcol will often have access to a greater breadth and volume of mortgage offers to cater for non-standard property types.
How Much Equity You Have
How much equity you can release to put towards your new property will depend on the lender's remortgage requirements and how much equity you’ve built up in your property. Whether the amount you can release is enough will depend on the value of the second property and what you can borrow on this new mortgage. The amount of equity you have is equivalent to your home's value minus your current mortgage's outstanding balance. Refinancing by remortgaging allows you to access this.
The more equity you’ve built up in your property, the more you can release to fund your new investment. Lenders will typically let you remortgage at up to 75% LTV (loan-to-value).
Your Personal Circumstances
Your particular circumstances - such as your income, employment status and credit history, will affect the remortgage deals you are eligible for.
Income and Affordability
Lenders will also look at your income and use it to determine how much they will lend to you. As remortgaging to buy another property will give you additional debt, you'll need to show the lender you can afford repayments on 2 loans alongside the costs of running 2 households.
Credit History
Some lenders may decline your remortgage application if you have bad credit. However, others take a more flexible approach, especially if the issues leading to your bad credit score occurred some time ago. Credit card debt and loans are typically only considered bad credit by lenders if you've missed repayments. Owing a large amount in either type of debt can also impact your chances of remortgaging, especially if the lender is unsure whether you’ll be able to manage both your debt repayments and your mortgage.
How Long Does It Take to Remortgage?
The timeframe for remortgaging to buy another property can vary depending on which lender you choose. The process typically takes 6 - 8 weeks, but it may take longer if any issues arise during the application process.
Even though you’re remortgaging to fund the purchase of a second home, commercial property or buy to let property, lenders will treat your remortgage application as a new mortgage. This can include a mortgage interview, credit checks, income and affordability checks and a property valuation.
Any issues or queries that arise from the property valuation can also hold up your mortgage application. If your property's current value is below what is outstanding on your mortgage, it could delay the process, or you may have to wait until the price recovers before continuing with your application.
