I have a commercial property with tenants in the auto business - dealership, mechanics and auto body shop. 

Until then, ignore them.Second, I like the basic mechanics of your system, but I'm thinking you may be missing out on a number of options that could enhance your system as you are currently running it. 

My investment group is looking at adding RV/Mobile Parks to our portfolio.

@Mark Abbate  I would not recommend looking at mobile/manufactured homes for potential rentals if they are in mobile/manufactured parks/communities. 

Mechanic, Magician, Mindreader.I've got the first and third skill down pretty good, still working on the second.

it's a very small (4 unit) mobile home park filled with 30-40 yr old park owned mobiles. the seller has not kept rent rolls and has very little to no documentation of rent history despite it being kept full (this area is very short on affordable housing). so, no proof of income and with the units being older it was tough to find a lender to work with me on it.

You will pay a higher premium, but will not get a 1920s product that has failing major mechanicals and other heaps of problems.   

@davidfairall (can't get "@" to work on mobile) Congratulations on your 1st deal + 1st year!!

The mechanics of an 1120S and Schedule K-1 from an 1120S don't work the way you laid out.

Yes the bldg will be under rent control, but as long as you vet tenants well and keep it a small unit, you can probably cycle through younger and upwardly mobile tenants that won’t stay there for 20 years.
