Documents You’ll Need
Finding a mortgage can be overwhelming, especially when you’re juggling property searches, solicitors and other buyers.
Portsmouth is a vibrant coastal city with a strong property market, driven by its naval heritage, growing student population, and proximity to the South Coast. From the waterfront apartments at Gunwharf Quays to family homes in Fareham Road and suburban streets across Fratton and Milton, our advisers know the Portsmouth market inside out.

We’ll track your case through underwriting, chase solicitors and other parties if needed and keep you updated through to exchange and completion. Once you’ve got your keys we’ll diarise a review before any fixed rate ends so you’re never left on an expensive standard variable rate.

Portsmouth offers an affordable entry point to coastal living on the South Coast. The city has seen consistent demand from first-time buyers, naval personnel, and investors attracted by its strong rental yields. Areas like Southsea remain popular for younger buyers, while Cosham and Paulsgrove offer more affordable family housing. Prices also remain below nearby Southampton, which keeps local demand strong.
Waterfront and city centre regeneration continues to deliver new homes across Portsmouth, creating opportunities for first time buyers and investors looking at modern developments.

Going direct to your bank gives you one set of lending criteria and one answer. Using a mortgage broker in Portsmouth gives you the entire market: high street lenders, building societies and specialist lenders that never appear on comparison sites. Our mortgage brokers are qualified, and Alexander Southwell Mortgage Services is authorised and regulated by the Financial Conduct Authority under reference 1011890, so every recommendation is tailored to your goal rather than to one lender's product range.
Your first conversation with our Portsmouth mortgage brokers costs nothing and carries no obligation. We look at your income, credit profile, any debts and your timescales, then explain in plain terms which mortgage lenders are likely to say yes. If the best mortgage for you happens to sit with your existing lender, we will say so.
Lending criteria vary enormously. One lender may cap borrowing at 4.5 times income while another stretches further for certain professions; contractors, company directors and applicants paid partly in bonus or commission are all assessed differently. The job of good mortgage brokers is to match your unique circumstances to the lender most likely to accept them first time, which can save money on wasted valuation fees and protect your credit file. That is how we find the right deal rather than simply the loudest advertised one.
A mortgage deal is not a one-off transaction. We diarise your product end date and contact you before you slip onto a standard variable rate, so you can review your existing mortgage, consider porting it if you are moving, or release equity for home improvements. Remortgage reviews get the same expert advice and the same service as your original application.
We arrange mortgages across the city and out towards Havant, Waterlooville and Hayling Island. Knowing which flats have short leases, where valuations tend to come in under offer and which developments have realistic completion dates makes a real difference to how smoothly your home buying journey runs. We handle the paperwork and do the liaising with lenders, agents and solicitors on your behalf.
We explain the terms of every mortgage deal we recommend: the interest rate, product fees, early repayment charges and the total cost over the term. You receive an Illustration in writing before you commit, so you can compare mortgage deals on the whole package rather than the headline rate alone. Any questions you have are answered before you proceed, not after.

Your home may be repossessed if you do not keep up repayments on your mortgage.

Yes. Alexander Southwell Mortgage Services covers Portsmouth and the wider South Hampshire area. Our advice is completely fee-free for standard residential mortgages. We earn a commission from the lender only when your mortgage completes, at no cost to you.
Most lenders require a minimum 5% deposit. Portsmouth property prices are generally lower than many nearby cities, making it more accessible for first-time buyers. A 5% deposit on a £200,000 home would be £10,000. Larger deposits of 10 to 15% will give you access to better mortgage rates.
Yes. Self-employed applicants in Portsmouth can typically apply with most lenders using two years of accounts or SA302 forms. Some specialist lenders consider just one year of self-employment history. We search the whole of market to find the best match for your circumstances.
An Agreement in Principle (AIP) is a written indication from a lender of how much they would be willing to lend you, subject to full underwriting. Portsmouth estate agents will typically ask to see one before accepting an offer. We can get yours sorted quickly, often within the same day.
