It's important to communicate with your lender as soon as possible to discuss your options.

If you're doing a rate and term refinance, there's typically not a seasoning period but again it's common for lenders to require it be rented first.If you're doing a DSCR cash out refi, it may not need to be rented first but you're probably paying a higher rate.Your best option is to call a loan broker you trust and go through the options based on your current situation.

but the exit was the lease option.. 

You’re thinking strategically, and it’s great to see you weighing all your options before making a move.
