Is there a waiting period after my loan closes to do a line of credit loan against the property?

first of all, howdy from the white mts of az I have lived up here for the last 11 years I will need some more information are you a purchase or a refi is it from the owner of the property? sometimes if you do a line of credit they have a 3 day time frame of buyers remorse it means you can get out of the loan

Assuming you mean after your first mortgage on a purchase or refinance closes,you should have no problem finding a bank or credit union willing to provide you with a line of credit immediately after your loan has been funded and recorded.Of course only some will allow you to go to 95% total loan to value, and many more to 90% total loan to value. On a purchase loan the purchase price would be used and many will use the appraisal you had just gotten per your home purchase or refinance.

There is no specific time requirement.

No, there is generally no waiting period whatsoever before attempting to take out a line of credit.
