Can you refinance your house after one month?

Yes, but there are a few questions that need to be asked before you do this-- Why are you doing this as they are closing costs to address--ones you just paid and the new ones?? Is there a termination fee or pre-payment penalty that has to be paid? Will the new lender use a new appraisal (if there is one- assuming you want cash out)or will they want to use the sales price? Most lenders want seasoning--meaning time in the house before a refinance is done. If you had work done on the house, you will have to prove it by specific receipts not just by a balance on a credit card. As you will have to prove that the credit card was not used for anything else but the house. Ask the lender questions first, before you start applying to make sure they can do what you are asking for.
