Joint Borrower Sole Proprietor

A great solution for young borrowers and parents who want help to increase their borrowing capacity.
The mortgage will be secured on your home. Your home may be repossessed if you do not keep up repayments on your mortgage.

At Family Building Society we can assist with a mortgage if you are moving home or would like to raise funds by remortgaging your existing property. Where you are seeking a Joint Borrower Sole Proprietor (JBSP) mortgage if you are raising additional funds these must be for the purpose of buying out another party to the mortgage, or for essential home repairs.

We have a number of mortgage products available. Take a look at our current range of mortgage products below.

 

Who can apply?

You can apply if you are aged 18 or over.

How do I apply?

  • Step 1 - Start by contacting our New Business Team on 03330 140140 or by using the Call Me Back form. They’ll go over some basic information with you including how much you would like to borrow and what for. They’ll need to know about your income and outgoings to make sure you can afford the mortgage and they’ll check that the mortgage meets our lending criteria.
  • Step 2 – After our New Business Team have reviewed your circumstances, they’ll refer you to our Mortgage Advice Team who will go through your circumstances in detail and recommend a suitable product. This advice is free of charge from our in-house team, or you can choose to use your own adviser (they might charge you for this).
  • Step 3 – Submit your application along with any supporting documents (there is a list of what’s required on our application form) and the £175 Application Fee along with any valuation fee which may apply. There will be further fees associated with the product selected.
  • Step 4 – Once the application has been assessed a valuation will be carried and then it will be underwritten and we will provide you with a Mortgage Offer. A copy of this will also be given to your nominated Solicitor who will contact you with some forms to be completed.
  • Step 5 – Once your nominated Solicitor has carried out the necessary searches and received the forms back from you we can arrange to send you the funds (this is called “completion”).
