The deeper your market knowledge, the stronger your relationships with agents, contractors, and lenders, and the better your deals will get over time.

Do you have a team of contractors yet to help you with these properties? 

Contractors can give you ballpark quotes on the spot, which will tighten up your budget.

I even try to unsell them on the business by sharing my financial losses, litigation,  market shifts, permit purgatory, shady contractors,  clouded title issues,  paranormal activity, squatters, mold, etc.

If you can, bring a contractor or inspector when you check it out to get a clearer idea of what you’d be dealing with.It sounds like you’re doing your homework, which is key!

One of the biggest factors in successful flips is building a strong team: contractors, agents, lenders, and property managers. 

Real estate agents, property managers, and contractors who specialize in your target market can save you time and money in the long run.

Alternative is to get a board certified real estate attorney to assist you.

The solar system adds no value to my property for rental purposes, and I may even be ripping up the roof & replacing it in the new year.Beyond sending a nasty letter through my attorney via certified mail, demanding the company come pick up their equipment, am I required to take any further action or fulfill any obligations regarding these contracts?

That is who you want.The best contractors will never, ever be on Yelp.
