A Joint Borrower Sole Proprietor mortgage allows two or more people to buy a property together, but with only one person taking ownership of that property. In this article, we answer one of your questions about JBSP mortgages, and hope to demystify this little known mortgage product.

Straightforward, no nonsense
"We got our mortgage through Newbury which was fixed for three years and ended in May of this year. They contacted us about a mortgage review, scheduled a meeting and gave us a better rate than we were on before. We didn't look around, but honestly even if there are better rates out there, the customer service you receive from Newbury is unmatched so that's a bonus in itself. Thanks to all the staff at Newbury, keep up the good work!"
