About a month after that initial email (last week), she called and emailed again disputing charges, threatening to sue, and asking for our energy bills to audit us (one meter was split between two units and payments based on percentage agreed upon by past landlord).

Would it increase risk of an audit?

There's probably a benefit to being an early adopter in that you take care of it before everyone else "has to" do it, but if you're too early then the infrastructure/products/know-how isn't there as much so you pay more than if you wait until demand is more widespread.Most folks I know, including myself, are taking a "wait and see" approach at the moment, but obviously folks that owner occupy might act earlier especially since it could benefit them personally.Now is a good time to recommend RISE Engineering, which does free energy audits of residential properties and then reduced-cost work if you do decide to implement some/all of their suggested improvements.My understanding is that it's free for the audit and reduced-cost for the work, because they get funded partly from charges everyone already pays on their electric/energy bills - i.e., it's subsidized by a tax we're already paying.

After college, I decided to enter the world of audit at an accounting firm.

Often if you go to the cost seg company you end up paying the same or less and some of the companies include audit defense for free in their overall price charged versus the accountant subbing it out to them to do the engineer part if there is an audit the accountant will charge usually per hour additional money to defend.There is nothing to say you have to sell all those houses you could sell some and then buy say a 3 million type property NNN.

@Amy SilvaAs long as you don't "screw up" your mortgage payments, you are probably okay.I was say you should check into potential gift tax issues should the irs audit you. 

No one wants to deal with a state audit or agency.

Everybody knows that and its generally fine for a tax audit. 

Learned from John Martinez and Never Split The Difference, specifically the deeeep anchor and accusation audit. 2) Having the right relationships/team to figure out how to fund great deals.Coronavirus is terrible and my heart goes out to all those impacted.
