I truly love BP but it does pain me to see so many people give responses to investors that totally discount different ways to invest. 

Usually inherited tenants are a a pain, even the good ones. 

That's not someone you want working for you.Of course you can and should ask about commissions, but I'd much rather have a sharp agent at full price than a weak or discount broker who leaves a pile of money on the table.

Then I made up my mind that I’d do what any self-respecting adult would do in this situation.I started up the car and drove home.It was just too painful to go in!

Vacancy will be your biggest and most painful expense, and the success of your investment will be determined by the quality of your manager and how effective they are at placing and maintaining good tenants.

@Tanner McGrew What a pain!

You will get a much higher return with more personalized mailers that directly speak to what the perceived pain point is.

The change order process with banks is painfully slow, and you’re going to want to keep the project moving.

Also - the most likely cause for a drop in real estate price (IMO) is a sharp increase in interest rates, meaning your monthly cash flow numbers/housing number is not likely to change dramatically with a decline in asset price.My 2 cents, start small... but get started! 

Yours sounds like a pain, I'd do it myself or get your HVAC guy to do it.
