Your adviser will compare mortgage products across suitable lenders and prepare a tailored recommendation. You’ll receive an Illustration (ESIS) showing the interest rate, fees and total cost over the mortgage term so you can make an informed decision.
We can often get a Decision in Principle (DIP) the same day or within 24 hours. This is essential when making offers on houses in popular Southampton areas like Freemantle, Bitterne Park or Ocean Village where competition can be fierce.
We’ll handle the paperwork, submit your documents to the lender, liaise on your behalf and arrange the valuation or survey. You won’t need to chase. We do that for you.
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.

Learn more about first-time buyer mortgages →Most Southampton homeowners remortgage when their current deal comes to an end, usually to get a better interest rate and bring their monthly payments down. But there are plenty of other great reasons to remortgage too. You might want to raise capital for home improvements, clear some debts or fund something special. It is also a really common route if you need to buy out a partner, or if you want to release equity to use as a deposit on a buy to let property. Whatever your reason, we search the whole of market and handle the full application for you, making the switch as simple and stress-free as possible. All at no cost to you.
Learn more about remortgage advice →Whether you are buying your first investment property in Southampton, looking to let your current home and move onwards, or you are an experienced landlord growing your portfolio, we can help you find the right deal. Buy to let mortgages can be more complicated than a standard residential mortgage, especially with the ever-changing rules around landlord responsibilities and taxation. Our advisers know this market inside out. We search thousands of products and advise on both personal buy to let and limited company structures. If you have multiple properties, we work with portfolio landlords too. All completely fee free.
Learn more about buy-to-let mortgages →New build homes in Southampton are a brilliant choice for first time buyers, households upsizing or downsizing, and investors looking for a low-maintenance property with great energy efficiency. There are some real benefits to buying new: you get a blank canvas to make your own, there is no chain involved, and most new builds come with a 10 year warranty for real peace of mind. That said, new build mortgages do have their own quirks. Lenders can ask for a bigger deposit, exchange deadlines can creep up quickly, and making sure your mortgage offer lines up with your build completion takes careful planning. As your local fee free mortgage broker in Southampton, we have access to specialist new build lenders and will manage the whole process from your reservation right through to getting your keys.

Yes. Alexander Southwell Mortgage Services is a local mortgage broker based in Romsey, just outside Southampton, and covers the whole Southampton and South Hampshire area. Our advice is 100% fee-free for standard residential mortgages. We are paid a commission by the lender when your mortgage completes.
Most lenders require a minimum 5% deposit. Southampton house prices average in the mid-£200,000s, so a 5% deposit is typically around £12,500 to £15,000. A 10% deposit unlocks more lenders and better rates. Some newer 99% LTV schemes allow deposits as low as £5,000 for eligible buyers.
Yes. Most lenders require two years of accounts or SA302 tax calculations, but some specialist lenders consider just one year of trading. We work with a wide panel of lenders and can match your self-employment situation to the right product.
An Agreement in Principle (also called a Decision in Principle or Mortgage in Principle) is a written confirmation from a lender of how much they are prepared to lend you. Most Southampton estate agents will want to see one before accepting an offer. We can arrange yours within 24 hours.
A bank can only offer you its own products, while a whole of market broker compares deals from dozens of lenders, including building societies and specialist lenders. Going direct can mean missing a more suitable rate or a lender whose criteria better fit your personal circumstances. We give advice based on the whole of market and manage the application for you from start to finish.
