Yes, it is possible to have two mortgages in Cardiff, though whether you are approved will depend on your income, existing commitments, and the purpose of the second property.
Many people assume you can only hold one mortgage at a time.
In reality, lenders are comfortable with borrowers holding more than one property, provided affordability and risk are properly assessed.
As a mortgage broker in Cardiff, we regularly help clients structure second mortgages for a range of reasons.
Why Would You Have Two Mortgages?
There are several situations where holding two mortgages makes sense.
You might be buying a second residential property before selling your current home.
You may be keeping your existing property and purchasing a buy to let in Cardiff.
Some clients buy a second home for family use or future relocation.
Each scenario is assessed differently by lenders, so the structure of the mortgage matters.
Can I Get a Second Residential Mortgage?
Yes, though lenders will look closely at affordability.
If you are keeping your current home and buying another residential property, the lender must be satisfied that you can afford both mortgage payments, alongside your other financial commitments.
Your income will be assessed in detail, and any rental income from the first property, if applicable, may also be considered.
Your deposit size will play an important role, too, as lower loan-to-value ratios reduce risk from a lender’s perspective.
Property prices in Cardiff can vary significantly between areas such as Pontcanna, Roath, and the city centre.
Understanding your borrowing capacity before making an offer is essential.
What if The Second Property is Buy To Let?
If you are buying an investment property, the second mortgage would usually be a buy-to-let mortgage rather than residential.
In this case, lenders will assess the expected rental income from the property to ensure it covers the mortgage payments by a required percentage.
They will still review your personal income and credit profile, though the rental calculation is a key part of the assessment.
If you already own your residential property in Cardiff, holding both a residential mortgage and a buy-to-let mortgage is common, provided the figures work.
Can I Have Two Mortgages Temporarily When Moving Home?
This situation often arises when you purchase your next property before your current home has sold.
In these cases, you may briefly hold two residential mortgages.
Lenders will assess whether you can afford both payments, even if only for a short period.
This is why planning early is important.
We review your equity, deposit, and income position before you commit to a purchase, ensuring the arrangement is realistic and lender-approved.
Does Having Two Mortgages Affect Credit?
Having two mortgages does not automatically harm your credit score.
What matters is that repayments are maintained consistently and your overall borrowing remains affordable.
Lenders will assess your total debt commitments when reviewing any new application.
Managing existing borrowing responsibly strengthens your position.
How Much Deposit Do You Need?
Deposit requirements depend on the type of second mortgage.
For a second residential property, lenders may require a larger deposit than for a standard purchase, particularly if you are not selling your existing home.
For buy-to-let mortgages in Cardiff, deposits are typically higher than residential mortgages, often starting at around 25%, though this varies by lender and circumstances.
Your equity in your current property may be used towards the deposit if sufficient value is available.
