it depends on whether you are in a costruction loan or a regular purchase loan.
it sounds like to me that since you aren't paying interest on the construction costs that you are actually just preapproved for a regular purchase loan on a home being built by a builder who is footing the construction costs themselves.
in which case, you can get preapproved again with just one party on the loan ap
when you answered "this is a construction loan", i wanted to make sure that you really werent in a construction loan where you were approved, underwritten and funded for the construction loan..... typically used by people using a small custom builder who asks his clients to foot the construction costs.
