Self Build Mortgage Information

With a self build mortgage, money is released in stages as the build progresses. Some lenders will lend you money to purchase land – typically 75% of the purchase price or value (whichever is lowest).

After this, the money for the build is released in stages. These stages can be fixed or flexible, depending on the lender, but usually there are six (see table below).

There are two methods by which the money can be released during the build – at the end of each stage (known as arrears stage payments) or at the start of each stage (advance stage payments).


Self build mortgage advice from WPP Financial Services, Rochester, Medway, Kent, could help with this.


With the arrears stage payment method, money is released after a valuer has visited the site and confirmed completion of the stage. This can cause some self-builders cash flow difficulties.

The advance stage payment method works in the opposite way, with money released at the beginning of a given stage, before work starts. This method has become popular as it provides positive cash flow during the build, making it easier to stay in your current house while the build progresses.

The stages of a build depend on whether or not you are building a traditional (brick and block house), a timber frame construction or if you are renovating or converting an existing property.
