Better income, less turnover, and less government intervention is my kind of business :)

You in no way rented to a government entity. 

See it doesn’t matter, there are no rules governing this.

Back a couple of years ago, there were financial government incentives to install the panels as well as very low (or possible no interest) loans.

However, if you are worried about being sued, you should use the best level of protection that you can afford.Your state laws: The laws governing asset protection vary from state to state.

I would also threaten to report the agent to the state board that governs real estate licensing.

They tried to keep the money until I pointed it out being in the acceptance letter due to knowing the date closing was on. also take in account how long it would be for them to do the paperwork. it is the government associated program, so you know they like to take their time on paperwork. 

After all, I'm talking to a government organization and we all know how that goes sometimes.

We have this thing called the 30-yr fixed mortgage, primarily because of the structure of the mortgage market with government backed mortgage securities.
