Yes, it is possible to have more than one mortgage at the same time. If you already have a mortgage and want to buy another property, a lender will need to establish whether you can afford the additional borrowing alongside your existing commitments.
The reason for buying the second property will also matter. You might be purchasing another home for yourself, helping a family member with somewhere to live or buying a property that you intend to rent out. The mortgage you need can differ depending on how the property will be used.
Having an existing mortgage does not automatically prevent you from borrowing again. Your income, expenditure, outstanding mortgage, deposit and the costs associated with both properties can all influence what is available.
As a mortgage broker in Newcastle, we can look at your existing mortgage alongside the property you want to buy and assess suitable options from the lenders we work with.
Can You Have Two Mortgages at the Same Time?
You can have two mortgages at the same time if you meet the lender’s affordability and eligibility criteria.
When considering another residential mortgage, the lender will want to understand the commitments attached to your existing home as well as the new property. This means your current mortgage payments and other regular expenditure can affect how much additional borrowing may be available.
Your income will form an important part of the assessment. Lenders will consider whether your earnings can support your existing commitments and the proposed new mortgage, using their own affordability calculations.
The lender may also want to understand why you are buying another property. Someone purchasing an additional home for their own use can be assessed differently from somebody buying a property with the intention of renting it out.
This is why getting another mortgage is not simply a case of repeating the process you went through for your first property.
How Much Deposit Do You Need for a Second Property?
The deposit required for another property will depend on the type of mortgage, how the property will be used and the lender’s criteria.
Owning another home can affect the loan-to-value, commonly known as LTV, that a lender is prepared to consider. Your circumstances and the property itself can also influence how much deposit is required.
You may already have savings available for the deposit, or you could have built up equity in your existing home. In some circumstances, homeowners consider remortgaging to release equity towards another property purchase.
Releasing equity increases the borrowing secured against your existing home, so affordability and the effect on your mortgage repayments need to be considered carefully. The amount of equity you have does not automatically mean you will be able to borrow the same amount from a lender.
There can also be additional purchase costs when buying another property, so it is important to consider more than the deposit when establishing your overall budget.
Why Might You Buy Another Property?
There are several reasons why you might want another mortgage while keeping your existing home.
You may want a second property that you and your family can use, perhaps because you regularly spend time in another part of the country. Some homeowners also purchase another property for a family member to live in.
Your intended use of the property is important because it can affect which type of mortgage is appropriate. If a family member will occupy the property, for example, the relationship to the occupier and the arrangements surrounding the purchase can be relevant to the lender.
If you intend to rent the property to tenants, you will generally need a mortgage suitable for that purpose rather than another standard residential mortgage. The lending criteria and affordability assessment can differ from those used for a home you intend to occupy yourself.
Being clear about the purpose of the second property from the outset means we can look at mortgage options that reflect how the property will actually be used.
Will Your Existing Mortgage Affect How Much You Can Borrow?
Your existing mortgage is an important financial commitment and can affect the amount you are able to borrow for another property.
A lender will usually look at your income alongside mortgage payments, loans, credit commitments and regular household expenditure. If you will remain responsible for the costs of two properties, these may also need to be considered.
The amount available can therefore differ considerably between applicants, even where they earn similar incomes.
Your credit history will form part of the assessment too. Maintaining two mortgages represents a greater overall financial commitment, so lenders will want to be satisfied that the proposed borrowing meets their criteria.
If you plan to use equity from your current home towards the purchase, we can also look at how increasing the borrowing on that property could affect the overall affordability of owning both homes.
Different lenders assess these circumstances in different ways, which makes it useful to consider the complete financial picture rather than looking at the new mortgage in isolation.
What if You Want to Rent Out the Second Property?
If you are buying another property with the intention of renting it to tenants, you would usually need a buy to let mortgage rather than a standard residential mortgage.
Buy to let mortgages are assessed differently from residential mortgages. The expected rental income from the property will usually form an important part of the lender’s assessment, alongside other criteria such as the deposit available and your circumstances.
You may be able to use savings for the deposit or, where suitable, release equity from your existing home. This means a remortgage and buy to let mortgage can sometimes form two parts of the same property purchase.
If you are considering buying a property to let in Newcastle, our mortgage advisors can look at the lenders we work with and assess the mortgage options available based on your circumstances and the property you intend to purchase.
