I'm fed up with the poor response times, the high expenses, and generally poor ROI (time and money) on using a professional property manager on one of my SFRs, so I'm planning on going to self-management.

This one in particular has original solid wood cabinets that have been previously painted (poorly done).

In California, it might be a minimum $5/ft.I'd say your best bet is to partner with a seasoned investor your first 2-3 deals.

Lot rent in the area is around $250.Most of the trailers are in poor shape, and park has been poorly ran. 

Oh, I bet.

I just purchased a single family rental a few months ago and I'm currently cash poor so I was going to use my $55,000 line of credit towards the this but I don't think the numbers make sense. 

I wouldn't calculate this into every month because if I had to put money on it I'd bet it doesnt snow in SD from June-Sept.- Im assuming this is billed directly to the property owner (you) from your local municipality or county.

Juliet, Brentwood, and Franklin might be your best bet.

So in that case, is it a poor financial decision to only utilize this once, with the mortgage insurance and everything?
