If you only have a small deposit, or do not have one at all, it may still be possible for you to obtain a mortgage.
There is a lender who will allow you to take out a personal loan to use as your deposit.
You need to pass the lenders affordability to show that you can afford the mortgage payments as well as the loan repayments. You will also need to meet the rest of the lending criteria.
However, this is ideal for someone with sufficient income but a low amount of savings.
