should i ask for holding deposit or signing lease now?

[Zhonna Chia]

i got the future tenant. but the house is not gonna be ready until early dec and future tenant is not gonna move in until mid dec. 

if i approved the application, should i ask for holding deposit which it will become the security deposit? how much? and any sample for the aggrement that i can see? .....

or just sign the lease for future move in date?

the property is in washington state.
