A joint borrower sole proprietor mortgage is a mortgage where the home buyer can add either a family member or friend's income onto their mortgage application. This specialist mortgage is a way for a family member or friend to help a buyer increase their affordability, without handing over any cash. It's a particularly good option for buyers who are still early on in their careers, so might be on lower salaries for the next few years, but expect their earnings to rise. Only the buyer will own the property (the "sole proprietor"), but your loved one will be on the mortgage as a "joint borrower", which means they will be liable to pay the mortgage if you cannot.
At Tembo, we call this an Income Boost. An Income Boost increases the amount that the buyer could afford, because the application is based on a higher combined income. It can also reduce the amount of house deposit required.
A joint borrower sole proprietor mortgage is useful for home buyers on lower salaries, as they can get on the ladder sooner or and afford more expensive properties than they would be able to afford by themselves.

Meet Hannah. In her mid-twenties trying to buy a home, Hannah earns £25,000 a year. Multiplying her earnings by 4 (a common sum used by lenders to work out how much they are willing to lend for a mortgage) gives Hannah £100,000 to buy a home.
With the average UK house price now around £230,00, without a very large deposit Hannah won’t be able to buy a property.
With a JBSP mortgage a parent or grandparent, for example, can add their income into the mix to increase the amount Hannah can borrow.
So if we take Hannah’s £25,000 income, and add to it her mum’s income of £38,000, that gives Hannah a total income (after the ‘boost’) of £63,000.
£63,000 x 4 (in the typical way lenders do for mortgages) = £252,000
That’s £152,000 more than on her own
With a deposit of £20,000 to £30,000, Hannah is in a much better position to grab her dream home with a JBSP mortgage.
Pros
A JBSP mortgage can be a good alternative to a typical joint mortgage. In both cases all parties are equally responsible for repaying the mortgage. But with a JBSP mortgage, because only the homeowner has their name on the property deeds, only they benefit from its value. This means that the other parties don’t usually have to pay capital gains tax or the 3% stamp duty surcharge
Having a higher income, boosted by a loved one with a joint borrower sole proprietor mortgage, may mean the homebuyer can achieve their homebuying dream with a smaller deposit. This can mean they are able to buy a property sooner, potentially savings thousands of pounds in rent.
Cons
All borrowers on the mortgage application will need to pass a credit check. Even if a parent is a higher earner and wants to help boost the income of their son or daughter to help them on the property ladder, if they are overcommitted with their own borrowings and outgoings – maybe their own mortgage is still big, or they have a lot of credit card debt – that will be a problem.
All of those named on the mortgage application will be liable for repaying the mortgage, but only the homeowner has any rights to the value in the property. So parents (or grandparents) who put their income at risk in this way will have no corresponding rights.
If the homebuyer can’t afford the mortgage repayments on their own they may have to sell the property.
The length of the mortgage term the homeowner is allowed will depend on the age of the oldest person named on the application. Most lenders require a mortgage to be paid off by age 80. This may limit your term if your boost is coming from a parent or grandparent, and so make monthly repayments higher.
Joint borrower sole proprietor mortgages can work out a cheaper and more convenient option for parents or grandparents trying to help sons, daughters and grandchildren onto the housing ladder.
