Hi everyone, wanted to know how soon typically takes to refinance a home to a different company. Currently have newrez for my mortgage loan and although I didn’t have any bad experience with them, I wanted to switch to a more reputable lending company like chase bank. What are the steps needed, and how soon after buying a house for the first time is a better time to refinance. What are the usual things a bank will look at before getting approved ?
Thanks I appreciate your responses.
