Residential Mortgage
A residential mortgage is a loan secured against a home you live in or plan to live in.
It may be used to buy your first property, move home, remortgage, change your borrowing, or review an existing mortgage deal. The right mortgage is not only about the interest rate. It is also about affordability, deposit, loan-to-value, repayment type, fees, lender criteria and how the mortgage fits your plans.
At Connect Lifetime Mortgages, we help clients understand residential mortgage options before they apply. This page is about general residential mortgages. It is not limited to later-life lending or equity release.
Your home may be repossessed if you do not keep up repayments on your mortgage or loans secured on it.
What Is a Residential Mortgage?
A residential mortgage is a loan secured against a property used as your home.
The lender provides the mortgage, and you repay it over an agreed term. This may be through monthly capital repayment, interest-only payments, or a combination, depending on the lender and product.
Most residential mortgages are used for:
- Buying your first home
- Moving to a new home
- Remortgaging an existing home
- Changing mortgage product
- Raising extra borrowing where suitable
- Reviewing mortgage options after a change in circumstances
A mortgage should be chosen with care. A lower rate may look attractive, but fees, repayment type, early repayment charges, term length and lender rules can change the overall cost.
Why Residential Mortgage Advice Matters
A mortgage is often one of the largest financial commitments a person makes.
That is why the first question should not be “What is the cheapest rate?” It should be “What is suitable, affordable and realistic?”
A residential mortgage adviser can help explain how lenders may view your case. This includes income, deposit, debts, credit history, age, employment type, property value and the mortgage term.
The UK mortgage market changes over time. Bank of England data for May 2026 showed lower mortgage approvals than the previous month, while the effective rate on newly drawn mortgages increased. In that kind of market, preparation matters.
Buying Your First Home
First-time buyers often focus on the deposit and monthly payment. Both matter, but lenders also look at income, commitments, credit history and the property being bought.
A larger deposit can reduce the loan-to-value, which may improve access to mortgage products. However, the deposit is only one part of the application. Lenders also assess whether the mortgage looks affordable now and sustainable in future.
Buyers should also budget for legal costs, valuation fees, survey costs, insurance, moving costs and tax where applicable. GOV.UK provides guidance on Stamp Duty Land Tax for residential property purchases.

Moving House
Moving home can raise extra questions. You may need to sell one property, buy another, review your current mortgage and check whether your existing deal can move with you.
Some mortgages are portable, but portability is not automatic. The lender may still assess your income, the new property and the loan amount. If your borrowing needs increase, the lender may treat the extra borrowing differently from the existing mortgage.
There may also be early repayment charges if you leave a current deal before the end of the fixed or discount period. This is why timing matters.
If you are planning a move, read our Moving House Mortgage page.
Remortgaging
A remortgage means moving your mortgage to a new deal, either with your current lender or a different lender. People remortgage for several reasons.
They may want to secure a new rate, avoid moving onto a standard variable rate, raise funds, change the mortgage term, or review the structure of their borrowing.
The right option depends on the current mortgage balance, property value, income, credit profile, fees and any early repayment charges. A lower rate may not always mean the lowest overall cost if fees are high or the timing is wrong.
If your current deal is due to end, our Remortgage page explains the next steps.
Self-employed mortgages
Self-employed borrowers can access mortgages, but the evidence route is usually more detailed.
Lenders may ask for accounts, tax calculations, tax year overviews, bank statements, company accounts or accountant details. The approach can vary depending on whether you are a sole trader, a limited company director, a contractor, or a partner.
Some lenders use salary and dividends. Others may consider retained profits or average income over several years. The structure of the business can affect the way affordability is assessed.

Affordability, income and loan-to-value
Mortgage affordability is based on more than income.
Lenders may review:
- Basic salary
- Bonus, overtime or commission
- Self-employed income
- Pension income, where relevant
- Credit commitments
- Dependants
- Regular spending
- Deposit source
- Mortgage term
- Property type
- Credit history
Loan-to-value, known as LTV, compares the mortgage amount with the property value.
For example, if you buy a £300,000 home with a £30,000 deposit, the mortgage is £270,000. That is a 90% loan-to-value mortgage.
A lower LTV usually means you have a larger deposit or more equity. This can affect the mortgage products available.
You can use our mortgage calculator to estimate monthly repayments. You can also use our affordability calculator as a starting point.
These tools do not replace regulated mortgage advice or a lender’s decision.
