I would sit back and really look at the situation from a NEEDS standpoint,, not a WANTS stand point and don't be pressured into doing something that will jeopardize a suitable living place that is currently sufficient. 

You won't be able to take a loan in the LLC's name until it's showing suitable profits to cover any loan it takes out.Remember who owns a property (has title) and who's responsible for paying back the loan (the guarantor) are two different things.

I let it dissolve in 2017 because i didn't think there was a future for the company at the time .Also the name of the LLC is not suitable for my new future strategy.

CO is Certificate of Occupancy that local agency gives to say building is in compliance with codes and suitable for occupying.

Also, assuming there aren't very many other suitable opportunities out there with my location requirements - would you recommend that I just proceed with my original plan of renting or buying a SFR, saving and keeping an eye out for other opportunities (which will likely never be in westchester, unless i go into less desirable places) - spending ~24k in rent or 15-20k in property taxes (for a house in a nicer area with a good school district) - that could be put into equity of a revenue generating apartment - FWIW - those houses I would buy are priced in the range of this apt complex, which puts off CF and has lower taxes.

From this I determine which on the surface appears to be the most suitable.

I have never seen a contract for deed that can be hadfrom the internet that is suitable to me.

Is there a matrix that shows which techniques are suitable for which situations and what skills need to be mastered for each technique?

There is a contractor around here, he uses an Amish crew, they pick up these junk trash cans and strip them, wood is recycled and they haul it for scrap, as they should IMO.An 8' wide trailer is fine for an RV or a deer camp, it is by no stretch of the imagination considered suitable housing.

As soon as you are not reachable the clients you've been hauling around for the last month will look at a property that is not suitable for them but will be talked into buying by a Realtor that is just looking for a sale.
