With the JPSB only the son or daughter’s name will be on the property’s deeds. This is because the parent’s name is listed on the deed of the home, but the child is not on the deeds of the property.

Pros and cons of a joint borrower sole proprietor mortgage

Joint borrower sole proprietor mortgages can be a total lifesaver if you’re struggling to get a mortgage.

To help you work out whether they’re right for you, here are the main pros and cons.



Because your parent or family member won’t legally own any of the property, you’ll be able to do what you want with it instead of having to make decisions with them.

Stamp duty: 

Your parent or family member won’t have to pay any stamp duty (a tax that’s charged on property purchases) if you get a joint borrower sole proprietor mortgage as they won’t own any of the property.



Even though your family member is helping to pay for the property, they won’t get any of the money if you sell it (although depending on how you look at it, this might actually be a good thing!).


Money can cause arguments and put a strain on family relationships. Make sure whoever helps you with the purchase, you both have each others trust 100%.


If you argue and your family member decides they don’t want to contribute towards your property anymore, it could be hard for them to get out of it & also have to pay certain legal & mortgage fees to be able to do so.


If either one of you stops paying your share of the mortgage repayments, the other one will be responsible as they are a legal owner.

JSBP – Joint Borrower Sole Proprietor mortgage FAQS

When I help my son/daughter with a JBSP mortgage, do I have to pay a second charge stamp duty?

The person that is supporting the purchase will not have to pay the 3% second charge stamp duty fee when helping their son/daughter buy a property with a JBSP mortgage because they hold no legal ownership over the property.

How does my joint borrower remove themselves from the JBSP mortgage?

Ending a JBSP mortgage becomes inevitable for some people because of a relationship breakdown. It can be difficult for the non-legal owner to have their name removed from the mortgage agreement without a deed of release.

This would only be granted on the basis that you, the homeowner, can afford to repay the mortgage on your own, without your supporter/parent’s financial help.

Many people who take out a JBSP mortgage, remortgage after a few years to an agreement without their supporter / parent’s help, alleviating the legal responsibility of any mortgage repayments from them.

Another option is to sell the property.

What happens if the legal owner dies?

In the event that the legal owner passes away before the end of the mortgage term, the executors of the legal owner are responsible for putting the property up for sale, with the intention of settling the mortgage from the proceeds.

Until the property is sold, the non-legal owner is legally obligated to pay the JBSP mortgage.

Use an independent no fee mortgage broker

Mortgages don’t need to be slow and in fact, a broker will speed the whole process up as they will communicate with all the different parties.

Once the lender has been chosen, your broker will also know what documents and information will be needed and will be able to submit this with the application. This can shorten the process to mortgage offer by as much as 2 weeks.
