Which means self employment tax.The residential treatment facility might be considered residential investment property or not depending on the level of care, regularity of assistance, and if the majority of tenants have long or short terms stays.A more careful analysis is needed for both of these situations to determine the taxable nature of these activities.

I am trying to decide whether I want to do a regular rental or owner finance the trailer and rent out the space.

Tenants have been paying on a regular basis for approx 2 years. 

@Matt Bonestroo it’s more of a how to get my license, is it the same as a regular car dealer license or is it a more specific license?

I also see good investors picking up enough deals regularly to make a very good living on.

In my experience folks on vouchers are no better or no worse then regular tenants.

If you sell in a "regular" park then you also need permission from the park owner, and they must approve the new buyer. 

Not to mention, there should be regular inspections done on your rentals. 

We cleaned the fan that took 2 minutes and told him going forward he needs to do his own house cleaning regularly.

This is a bit of an odd situation so it's not something I will deal with on a regular basis.
