What is a self-build mortgage?

If you’re early into your research into building your own home and self-build mortgages, you may be wondering what a self-build mortgage is?

To put it simply, a self-build mortgage refers to a mortgage designed to cover the costs when you are building your own home. These mortgages may be a little trickier to find than traditional mortgages, but you will still have plenty of options for self-build mortgage providers if you shop around.

Usually, when you apply for a self-build mortgage, you won’t receive the funds as a lump sum, like you would for a traditional mortgage. Instead, the funds will be released throughout the different stages of your property build.

How are self-build mortgage rates calculated?

After speaking to different self-build mortgage providers, you will be offered a number of choices, each with varying interest rates. If you and a friend both decided to build your own homes, it is unlikely you would both be quoted the same mortgage rate due to a number of factors. But, how are self-build mortgage rates calculated?

Firstly, the amount of funds you are borrowing will affect your mortgage rate. Generally, the less you need, the lower the interest rate will be. In addition, self-build mortgage providers will look at the amount of your deposit, your credit history and the current market conditions.
