Frequently asked questions
What profit margin do lenders require?
A profit on cost of about 20% is the conventional hurdle for residential development finance. Below that, most construction lenders will either decline or require more equity.
What is residual land value?
The most you can pay for the land and still achieve your target profit. It is the standard way to test whether an asking price works, rather than starting from the price and hoping the numbers land.
