There aren't really any mobile home parks close that I know of.But there is this neighborhood with 5000 sq ft lots that have MH and some older built regular homes.  

Do you find your experience using this strategy better than regular SFH 

Modular houses are not the same as a regular one.

I eventually stopped the service and just left them plugged in so people thought there was noise monitoring in place lol.

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.

They should agree to credit repair and monitoring as well.

@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.
