Thanks.Well you’ll have to make sure the SFH has enough parking and is big enough for the split.

Possibility of buying trailer park   A guy mention he wants to sell.

For the ongoing/routine items, I'm less sure - though have a pretty good idea of some routine stuff, like lawn mowing, other things feel like a complete guess, like how many plumbing calls will I'll need per year per unit? 

There are some issues that came up with the property inspection and it needs a new roof, new commercial rtus, and repaving the parking lot.

The way I see it is that the monthly fee should cover coordinating routine maintenance (HVAC tuneup or minor maintenance, leaky faucets and drains, sprinklers, minor pest control, etc.), but larger ticket items that may require multiple bids, permits, or otherwise could have reasonably been prevented should be handled separately and charged to the owner.

The friendly landlord laws, typically lower tax burden, and population/job growth have made the SE a great place to park assets. 

Upon closing escrow on a small apartment, I removed 2 transients from an ajointing lot, because they were encamped against the back wall of my parking garages.

Zoning - There is a whole template in the STR Handbook (too large to post here) that will let you know what your house zoning means, and what the requirements are for your zoning (parking, etc).
