A mortgage is a loan secured against your home. Your home may be repossessed if you do not keep up repayments on your mortgage or any other debt secured on it.
The mortgage market is a complex, multi-faceted arena, with diverse offerings designed to cater to various home buyers’ distinct needs and situations. Part and part mortgages are gaining prominence among these diverse offerings due to their inherent adaptability and potential advantages. As an experienced and trusted independent mortgage broker in London, Your Mortgage Experts is committed to shedding light on the complexities of part and part mortgages, offering comprehensive insights into their benefits, key considerations, and the application process.
What is a Part and Part Mortgage?
A part-and-part mortgage combines repayment and interest-only mortgages, allowing borrowers to split their mortgages into two parts. One portion pays the principal and interest, while the other solely service the interest. This structure is a hybrid of a variable rate mortgage and a repayment mortgage, offering flexibility and appeal to many borrowers.
One of the distinct features of a part and part mortgage is the degree of control it offers borrowers. Borrowers can decide how much of their loan is allocated towards repayment and how much towards interest only. This flexibility can facilitate better financial management and potentially lead to lower monthly payments, creating a less burdensome financial commitment for borrowers.
How does a part and part mortgage work?
Part and part mortgages are not standardised. It combine both repayment and interest-only methods of repaying a mortgage. The borrower chooses what percentage of the loan will be repaid under each type, typically around 80% repayment and 20% interest-only. The maximum amount that can be interest-only is usually linked to the loan-to-value ratio of the mortgage. Your lender will customise how much capital you pay off as you go and at the end. Although the specifics of a part repayment, part interest mortgage are flexible, you’ll need to repay a substantial portion of your mortgage on a repayment basis.
Paying back the interest only part
When applying for a part and part mortgage, borrowers must present a “repayment strategy” to prove their ability to repay the remaining amount. All lenders will be keen to understand your plan for repaying the outstanding balance for the interest-only component at the end of the term. They’ll want to see concrete proof of this plan.
The Nature and Value of the Property: Lenders often perceive interest-only arrangements as riskier. If the property in question is non-standard, it adds an extra layer of risk that could impact a lender’s readiness to grant you a part and part mortgage. However, specialist lenders might consider such scenarios accessible through a broker.
The Deposit Amount: A larger deposit lessens the risk for lenders. Most lenders typically accept a maximum loan-to-value (LTV) ratio of 85% when considering a part and part arrangement. Therefore, a lower LTV ratio would undoubtedly work in your favour. Like any mortgage application, the heart of the assessment is your ability to repay the amount you request to borrow feasibly. Therefore, you’ll also need to present information about your income and expenses, any existing debt, and credit history.

Remortgaging possibilities
Given the long-term nature of mortgages, changes in your financial circumstances over time are likely. In such cases, remortgaging can be an option. For instance, a remortgage can provide flexibility if your originally planned repayment strategy becomes impractical or you wish to start repaying a larger portion of your mortgage sooner than initially planned.
Switching to a repayment mortgage
Although you can certainly switch from a part-and-part mortgage to an interest-only or repayment mortgage during your loan period, it’s essential that you demonstrate the financial ability to repay the larger loan amount for an interest-only arrangement or manage higher monthly repayments in case of capital repayment mortgages. Unfortunately, this process could be slightly more complicated than expected, as conversing with a mortgage lender or mortgage broker may be necessary
The considerations when switching from a part and part mortgage to a repayment mortgage are that the monthly repayments will be higher, as the entire mortgage amount needs to be paid back over a shorter period.
Transitioning to a repayment mortgage
In such instances, the goal of remortgage often involves switching to a repayment mortgage. This approach can be beneficial when your income increases and you wish to repay your mortgage more conventionally. Moreover, if you meet all your repayments on schedule, you won’t have an outstanding balance at the end of your term. Read our guide on 5 important things to know in order to remortgage.
What happens if my income changes?
If your financial circumstances deteriorate, remortgaging might become challenging. Each time you alter your mortgage, the lender will conduct an affordability assessment to ensure you can comfortably manage the mortgage. If your finances are strained, you could fail to meet the affordability criteria. Hence, it’s crucial to proceed with caution in such situations or contact our advisors for assistance.
