YOUR HOME MAY BE REPOSSESSED IF YOU DO NOT KEEP UP REPAYMENTS ON YOUR MORTGAGE.

What is a residential mortgage?

A residential mortgage is a loan used to buy or remortgage a property that you plan to live in yourself. This could be your first home, your next home, or an existing property you already own and live in.

Residential mortgages are usually assessed on affordability, income, deposit size, credit history and lender criteria. The amount available, the rate offered and the products you can access will often depend on how strong your application looks overall.

For many borrowers, the key variables are income, deposit and credit profile. For others, the main challenge may be self-employed income, a more complex employment pattern, or finding the right lender for a particular set of circumstances.

Who we can help

Residential mortgages are not just for one type of borrower. RHER can help clients across a broad range of situations, from first-time buyers through to experienced homeowners reviewing their current mortgage.

First-time buyers

For clients taking their first step onto the property ladder and trying to understand deposits, affordability and the buying process.

Home movers

For borrowers selling one home and buying another, including those looking to borrow more or restructure their mortgage.

Remortgage clients

For existing homeowners reviewing rates, raising funds, or changing mortgage arrangements.

Self-employed applicants

For sole traders, company directors, contractors and business owners who may need more tailored lender research.

Family-supported buyers

For children or grandchildren receiving help from family with a deposit or broader purchase support.

Deposits and loan-to-value explained

One of the most important parts of a residential mortgage is the relationship between your deposit and the size of the loan you need. This is known as loan to value, or LTV. The higher your deposit, the lower your LTV will usually be. The lower your LTV, the more mortgage products and potentially better interest rates may become available.

Many buyers enter the market with a 5% or 10% deposit, while others may be able to put down 15%, 20% or more. In general, lower-deposit mortgages can be helpful for getting onto the property ladder sooner, but they often come with higher rates and stricter criteria than lower-LTV products.

Example 1: 95% LTV

Property price
£200,000
Deposit
£10,000
Mortgage needed
£190,000
LTV
95%

Example 2: 80% LTV

Property price
£200,000
Deposit
£40,000
Mortgage needed
£160,000
LTV
80%

That is why a larger deposit can sometimes reduce monthly costs, improve product choice and strengthen the overall application.

How much might you be able to borrow?

Mortgage borrowing is usually linked to income, affordability and lender criteria. As a broad guide, many lenders work with income multiples of around 4 to 4.5 times annual income, although some may offer more or less depending on the circumstances, the applicant profile and the product type.

That does not mean every applicant will automatically qualify for the same multiple. Lenders also assess committed expenditure, credit history, household circumstances and interest-rate stress testing when deciding what they may be willing to lend.

Sole applicant, £40,000 income

A broad guide may be around £160,000 to £180,000, subject to affordability and lender criteria.

Joint applicants, £70,000 combined

Borrowing may be higher because two incomes support the application, subject to affordability and lender policy.

These are only broad illustrations. The actual amount available can vary significantly depending on the lender and your circumstances.

Employed and self-employed mortgages

Employed applicants will usually be assessed using salary, employment history and payslips, along with the lender's affordability model. In many straightforward employed cases, the process can be relatively simple if the income is stable and well documented.

Self-employed applicants can still access residential mortgages, but lenders often want more evidence of income and trading stability. This may include SA302s, tax year overviews, company accounts, salary and dividends, or accountant-prepared figures depending on how the business is structured.

Being self-employed does not mean you cannot get a mortgage. It usually means more detailed packaging and more careful lender selection. That is where advice becomes particularly valuable.

Employed applicants

  • Usually assessed on salary and payslips
  • Often simpler income evidence
  • Strong employment history can help

Self-employed applicants

  • May need more proof of income
  • Could include sole traders, partnerships, limited company directors, freelancers or contractors
  • Lender choice is especially important

First-time buyer situations we can help with

First-time buyers often assume there is only one route into home ownership, but in reality there can be several ways to structure a purchase depending on deposit, income and family support.

Scenario 1

Low deposit first-time buyer

A buyer with a 5% deposit may be able to access a 95% LTV mortgage, helping them buy sooner. The trade-off is that rates may be higher and product choice narrower than for a buyer with a larger deposit.

Scenario 2

Buyer improves deposit over time

A buyer who increases their deposit from 5% to 10% may reduce their LTV from 95% to 90%, which can improve product choice and potentially reduce the interest rate available.

Scenario 3

Joint first-time buyer case

Two applicants buying together may be able to borrow more than one applicant alone because the lender is assessing two incomes rather than one, subject to affordability.

How family support can help with a deposit

For many first-time buyers and younger borrowers, family support can make a meaningful difference. One of the most common examples is a gifted deposit, where a parent or close family member gives money towards the deposit with no expectation of repayment. Lenders will usually want this confirmed in writing, because a gifted deposit is normally expected to be a genuine gift rather than a loan.

Family help can improve a purchase in different ways. It may help a buyer reach the minimum deposit needed to get onto the property ladder, lower the LTV to access better rates, or make it possible to buy a more expensive property that would otherwise be out of reach.

A buyer wants to purchase at £250,000. With a 5% deposit they need £12,500 and would usually be borrowing at 95% LTV. If family gift an extra £12,500, the deposit becomes £25,000 and the LTV falls to 90%, which may improve product choice and pricing.

Parents could also raise funds to gift from their own property, via a lifetime mortgage or later life lending mortgage, as an advance of an eventual inheritance.

  • A gifted deposit usually has to be a genuine gift, not a repayable loan.
  • Lenders and solicitors will usually ask for proof of source of funds and a gifted deposit declaration.
  • Family support can be very helpful, but it should be structured properly from the outset.

Why mortgage advice matters

Even relatively straightforward residential mortgages can become more complex when deposit size, income type, credit history or family support comes into play. A deal that looks attractive online may not be the best fit once lender criteria and the full application are considered.

RightHomes Equity Release can help compare mortgage options across the wider market, explain the differences clearly, and guide the application through properly from the outset. That is particularly valuable for first-time buyers, self-employed applicants and family-supported purchases, where the right lender choice can make a significant difference.
