Depending on the location, level of experience, asset value etc etc we have got upto 70% net GRV.
It is usually GRV or percentage of cost whichever is lesser.

On a residential deal you wont get a lender lend against GRV so will be a percentage of fixed price cost.
On a development deal you would get a a loan based on GRV however you are looking at different rates, fees etc.
