Welcome toCornerstone Mortgages

Cornerstone Mortgages is a trading style of Regal Finance Group Ltd which has a total of 15 advisers and administrative staff covering the UK. Cornerstone was established to focus mainly on the Bucks, Oxon and Northants areas, with mortgage and protection advice provided by Simon Garnett
As regulated mortgage brokers, our core mortgage business will always be purchases, remortgages and product transfers. For these, we use a range of lenders to include, but not limited to, the Nationwide, HSBC, Barclays, Nat-West, Santander and the Halifax.
We can also assist with help-to-buy, shared ownership and parental assisted mortgages and even have a panel of non-conforming lenders for those clients with more specialist requirements.

Whether you’re a first time buyer, a home mover or an investor, our main priority is always to find the right mortgage for you.

Simon Garnett

I am a professional mortgage adviser who has worked within the financial services industry for over 25 years. Traditionally, I have worked alongside estates agents and introducers in the Northants, Oxon and Bucks areas to provide a mortgage advisory service. With that service, I bring a wealth of experience and an unblemished record in Financial Services.

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

Simon has arranged mortgages for myself and my family for the last 18 years. He always finds us the best deal and somehow manages to get the mortgage approved and offered ahead of schedule. Would never use anyone else, even though a good friend’s husband is in the same business. Totally recommend!

Sue – Newcastle upon Tyne

I’ve been dealing with Simon for over 5 years now and he has recently helped me with two extremely complicated mortgages. His advice always revolves around what’s best for you as a client and the service he offers is always one full of integrity and honesty. I’ll be Simon’s customer for life and I’d happily recommend him to anyone.
