How much of a % is needed down for having a house built?

I know it depends on the cost but I wasn't sure if it was 15%, 20% or whatever. I live in Tennessee also. ThanksHow much of a % is needed down for having a house built?
you can get up to 100 percent financing for a construction loan. shop around and compare the different rates for different down amounts. some loans don't even require any payment until you file a certificate of occupancy.How much of a % is needed down for having a house built?
It is usually 20%. More if you can afford it.
