We also have an offer in on a single family in Menasha to use as an AirBnB. 

Just to clarify your original post,  is the current property just rented out as a single family residence? 

It's two bedroom, two bath, needs new windows, doors, insulation (particularly the second floor), electric, plumbing, HVAC, kitchen, and the detached garage (single car) rehabbed as well.

To use the VA loan to purchase a single family home would require us to move once again which is costly, not to mention it would be the sixth time in 3 years for out family.

I'd go for a well-maintained single family or two family with much higher rents per unit and much lower headaches.

If the "air conditioner" you referred to in your post is a window unit that would fall out when you turned the house upside down, then it is 5-year personal property; otherwise, 27.5-year propertyLandscaping and ground improvements are 15 year property that would include driveway and sidewalks.For a single family rental, a cost segregation study is most likely more expensive than your tax savings could ever recover through accelerated depreciation. 

So, in a few of the single family houses I have recently purchased for rentals, the basements are fairly humid. 

Hey everyone hope you guys are all doing well.I am reaching out to everyone because I want to get my foot in the door into the real estate world and would love to work with a team or single person who is flipping houses, doing rentals, etc.

Since then, I've been approved for a new single family construction loan (currently in underwriting).

I'm not opposed to Single Family Rentals, but looking to optimize economies of scale.
