I've been on both sides of the coin.

My coin. 

I need to buy 3 pairs of coin op washers / dryers for 2 4-6 unit properties.

I'm purchasing a six unit in KCMO that has coin-op laundry machines.

Hi Guys, anyone have experience on changing existing washer and dryer into a coin operated machine?

Here in FL there is an advantage to having the RM with a broker as opposed to being with a title co.....in the event of a dispute, the broker has more latitude. 

I researched and located the best STR Co in Central Florida and believe that to be iTrip.

Cap ex should be a part of your cash flow analysis but not technically part of NOI.On the flip side of the coin, many lenders will include cap ex reserves in their underwriting and NOI.  

I need to ask my fellow Minnesota investors how they approach adding a coin-op or just commercial washer and dryer to their apartment. 

However, the cash flow on 3 smaller homes bought right, say each cash flows 150 per month,  that would be a cash flow of 450 on the three, which might exceed the cash flow on one single family 200 K property.The other side of that coin, sort of to @David Krulac's point, is that your 200 K is divided into three units which is three times the hustle work for your money.
