Self Build Mortgage Choice

It makes sense if you buy a plot of land, buy materials whilst paying wholesale rates, and then employed labour directly, as you will be buying a house at cost price. You would be paying what a house developer has to pay, but you don't need to add on your marketing and sales costs and a profit margin.

Many banks and building societies offer mortgages to self-builders. They are usually willing lend you between 25% and 80% of the land's value in addition to between 65% and 95% of the building costs. Any money for construction is paid in arrears usually, once key stages of the building work are completed.

Under different self build mortgage choices, there are three basic choices of paying interest, namely Variable rate, where the rate can go up or down, fixed rate, where the rate is fixed for a pre-determined period, and capped, where the monthly payments have a maximum for a guaranteed period.

The variable rate mortgage means the interest rate may change. In general, the standard variable rate (SVR) charged by the mortgage lender will mirror the Bank of England Base rate, so you should monitor that rate to suggest what your mortgage rate may be.

A capped mortgage is a combination of fixed and variable mortgage. There is a maximum rate over which you will not be charged for a certain period. If the SVR falls below the cap, your payable rate follows it down.


On the other hand, with a fixed rate mortgage, you are guaranteed to pay a certain level of monthly payments for an agreed period.
