Assuming my alternative options would be: - Refinancing with here on the loan?

While you can use your own funds, alternative sources like hard money lenders and private money lenders offer distinct advantages.

Keep the FHA loan as an alternative if capital constraints arise.

My alternative would be living in a single family for a year and renting out. 

They'll understand this investment and be able to give you alternatives that are much less risky.

This is why I never fill a vacancy until the unit is vacant because often times tenants have last minute changes in their plans and an average tenant may not have the ability to make alternate accommodations.If you are using the PA lease provided to realtors, check out paragraph 21 about holdover tenants.

Alternatively there are also asset based lenders that do not require DSCR calculation or income verification, that can be less costly than hard money, and fully amortizing.

Alternatively, how much would you pay a professional to fix this?  

Alternatively, you could move straight into a longer term program that will essentially structure the deal as a "delayed purchase" and underwrite in place DSCR/occupancy.

Alternatively, you can pay $119 per unit that vacates.
