you can use FHA again but have to move within 100 miles of the first property, also certain conditions apply under using it again ( new job , new baby etc)

They are seriously overpriced for the condition and need alot of maintenance.

The sellers know the market conditions and know other people will line up to purchase the property "as-is". 

With that said, if the tenant's have been paying on time and have kept the home in overall decent condition, then I don't see any trouble listing tenant occupied.

Without knowing the exact location or condition of the property I can't provide exact advice, but Id looks into other rental forms such as either Medium-term furnished rentals, or rent by the room to increase the rental income.

Metrics like ROI and cash flow only predict how a property is likely to perform on day one under ideal conditions.

Hey @Neil FredericksonI tried to post earlier but it got removed for breaking terms and conditions of posting in the forums....as I'm sure this one will be as well.  

We set up new park rules and leasing guidelines and slowly cleaning up and improving the park condition.

A lot of our properties that we are seeing in the area are in run down condition but have a lot of potential.

Given the condition of the home you are better to let them leave and clean it up VS wasting your time.
