How Do Self Build, Custom Build And Conversion Mortgages Work ?

The main difference between self build and custom build mortgages over a traditional mortgage is that the money is released in stages as the build moves forward, rather than as a single amount.

Lenders will release funds for clients to buy land, subject to the plot having a minimum of outline planning or permitted development rights.

Typically 20% cash deposit is needed against the cost of the whole project (purchase of land & build costs).

Those who already own land and have detailed planning agreed can use the plot value to draw funds on day one of the build.

Funds can be released in advance or in arrears of each build stage. The cash flow of your project will dictate our recommendation to you.


A Self Build, Custom Build or Conversion is a lot more complex than a standard purchase. Mayfairlife and mortgages are very experienced in property development projects and understand the importance of cash flow, therefore we help to ensure you have enough money to fund your project day to day with no delays. We understand the importance lenders place on certain areas of underwriting such as location of the plot, affordability, income & construction method.
