Unless you bought in D class, very low appreciation area, you should be sitting pretty. 

While it doesn't specify the rents, I'm coming up with around $733/unit.If we use a 7% cap rate (and I suspect that cap rate is low, but I don't know the local market) on the one on Harvard, you'd probably need to charge over $1,000/month for the Harvard units to get an ARV of $1M. 

Assuming a 40% expense ratio, the net operating income at the current income level would be around $19,440 annually and $28,800 after renovations.At a $360,000 asking price, the cap rate based on current NOI would be 5.4%, which is low for a park with park-owned homes and required renovations.

I don't do app development but I was told for most sites and businesses it's a lot of work for low payback.

THe lender is a credit union and it is a conventional low rate loan.

There are also several funds out there that provide high single digit yields that are low risk. 

I am currently employed as a project engineer working for a GC that builds multi-family projects.

However, the rental value this area is very low compared to the Home values and mortgage rate.

Fully furnished 6 month (maybe as low as it was3-4 months) is much closer to a LTR.  

I appreciate the reminder as well that if the gain is fairly low then it may make more sense to just pay the capital gains taxes now versus 1031 exchange.
