Purchase with Cash then refi VS just financing

[Casey S.]

I have done some cash purchases and purchased with financing also. I dont really have any refinance experience. I am looking at purchasing a home that we would like to get closed on fast due to the rental season where I live. Obviously cash speeds things up, which we can do, but we would really like to have it financed for 30 years at a low rate with one of the big banks/ lenders.

Are there any up sides or down sides to refinancing after closing a cash deal vs just financing it to start with?

Thanks!
