This is a type of mortgage arrangement where one or more individuals (joint borrowers) apply for a mortgage with the intention of helping a sole proprietor (the sole owner) secure financing.

Here’s how it typically works:

1. Joint Borrowers: These are individuals who agree to take on the mortgage with the sole proprietor. They could be family members, friends, or business partners. They co-sign the mortgage, which means they are also responsible for the loan repayments.
2. Sole Proprietor: This is the individual who runs their own business and is looking to get a mortgage. As a sole proprietor, their income is often less predictable compared to salaried employees, which can make it harder for them to qualify for a mortgage on their own.
3. Purpose: The joint borrowers help to strengthen the application by adding their income and creditworthiness to the mix, which can make it easier for the sole proprietor to secure the mortgage. This arrangement can be particularly useful for sole proprietors who may have irregular income or need additional support to meet lender requirements.

In essence, a JBSP mortgage can be a practical solution for sole proprietors looking to secure a mortgage by leveraging the financial stability and creditworthiness of others.
