Your question is unclear. Qualify for financing in 3-6 months? Sounds like a purchase, not a rental.
Is it that you're looking for a short-term rental with hopes of purchasing some place? Or is it that you're looking at incredibly short-term lease-options?
Work with your Realtor and a lender. Position yourself financially to accomplish whatever it is you're aiming for. And if you can't qualify for financing in 3-6 months, adjust your plans accordingly.
Good luck.... more
