How Much Can You Borrow?
The good news is if you can afford to buy a house, it’s likely a lender will agree a self build mortgage. How much you can afford to splash out on your new home will be restricted by the amount of money you can borrow, but it is possible to run a self-build mortgage along side your existing mortgage if you’d rather not sell your current home.
Self build lenders use the same income multiples as for traditional mortgages, so you can typically borrow up to 3.5 times a couple’s joint income or 4.5 times a single borrower’s income – although your ability to afford the mortgage is the key here.
Applying For A Self Build Mortgage
Getting a self build mortgage is more complicated and involves more paperwork than a traditional mortgage.
