Even PS blowing up is not really news, it was expected.

I have been a long time lurker but I am now starting to take action with my real estate investing.

Real estate investing is more about taking actions and learn as much as possible along the way and not repeating your mistakes.

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?

The CFPB made it very clear recently that all of the same consumer protections apply to them: CFPB Takes Action to Stop Contract-for-Deed Investors from Setting Borrowers Up to Fail There are very few if any places these days where you're just going to easily toss a borrower out with a land contract.

The more actions you take of course the more money you will save but it will take more time, effort and energy while there is a learning curve which often times can be pretty steep in this industry. 

If you’re truly convinced the country is going “socialist” then you should probably buy gold and turn off the news.

The best course of action is probably a HELOC.

Just take action you do not need a mentorship.

Focus on actionable steps like analyzing deals, attending local meetups, and exploring niches like wholesaling or house hacking.
