I’m Charles Calvert, a mortgage broker at Easy Mortgages. This is general information, not personal advice. Always check the figures against your own situation before you decide anything.
“How much can I borrow on a mortgage in Portsmouth?” is one of the first searches local buyers make when they start house-hunting. Income multiples are only the starting point. Lenders look at the whole picture.
Mortgage rates remain well above the ultra-low levels many buyers got used to before 2022, so deposit, term and product choice all need a clear plan.
More than salary
Lenders look at income — employed, self-employed or mixed — but also credit commitments, household outgoings, deposit size, credit history and how stable your work looks. Two people with the same salary can be offered very different maximum loans if one has car finance, child maintenance or a busy credit card picture and the other does not.
Affordability tests in a higher-rate world
Automated calculators stress your finances against higher notional rates and check that essential spending still fits. That is why a headline “four-and-a-half times salary” rule of thumb fails so often — and why borrowing maximums felt different when rates were near historic lows. Cutting unused credit cards, clearing small loans where it makes sense, and avoiding new finance before you apply can all help the picture — without magic guarantees.
Deposit still changes the answer
A larger deposit lowers the loan-to-value and can improve both rate and how lenders view risk. In Portsmouth and Southsea, where prices vary sharply by street, knowing your deposit and a realistic borrowing figure together stops wasted viewings above your range.
Portsmouth price context
City centre flats, Southsea family homes and surrounding postcodes sit at different price points. Your maximum borrowing is not a target you must use. Many buyers choose a lower loan so the monthly payment leaves room for life, commuting and maintenance — especially while payments buy less borrowing than they did in 2021.
Talk it through without jargon
I am happy to run an affordability chat in plain English. Initial advice carries no fee and no obligation. If we later arrange a purchase mortgage, the fee is £495 once you receive a full offer.
What to have ready
- Latest payslips or self-employed tax documents.
- List of monthly credit commitments.
- Deposit amount and where it is held.
- Any expected gifted deposit (with donor details).
- A rough property price range for the Portsmouth areas you like.
Joint borrowing and gifted deposits
Adding a partner’s income can raise the maximum, but it also brings their credit file and commitments into the assessment. A gifted deposit raises how much you can bid without necessarily raising the loan. Sometimes the smarter move is a larger gift and a smaller loan so the monthly payment stays comfortable in a higher-rate market.
Bank statements tell a story
Underwriters read your statements. Regular gambling spend, returned direct debits or unclear cash deposits invite questions. Tidying spending for a few months before you apply is dull advice and also effective. Portsmouth buyers who arrive organised usually get clearer decisions faster.
A quick Hampshire checklist
Before you act on anything in this article, write down your target property price or current balance, your deposit or equity, your deal end date if you have one, and the monthly payment you could comfortably afford if rates moved again. Bring that note to a broker chat and we can turn it into live illustrations. Easy Mortgages is based in Fareham and works with clients across Gosport, Portsmouth, Southampton and the wider county.
None of the examples here are a personal recommendation. Products, criteria and tax rules change, and your credit file and income decide what is actually available. A short conversation usually clarifies more than another hour of search results.
Finally, treat the maximum borrowing figure as a ceiling, not a target. Many Portsmouth buyers sleep better with a payment that still allows savings and maintenance — especially while rates sit well above the ultra-low years. I would rather help you win a slightly smaller home comfortably than stretch to a payment that only works on paper.
