I'm cautiously optimistic about 2020, and war with Iran is not happening. 

As others have mentioned that does sound fairly thin and some of the numbers you mentioned for expense seemed optimistic.

I can't comment on how effective they are yet, and there is a moderate one-time fee, but I'm optimistic.

So assume a real cash flow of $200/month unit (which I personally think is optimistic in the cheaper Midwest markets), you would have $2400/year.  

That's a given IMO but I suppose some people don't do that and end up at the mercy of someone else's optimistic math.

It turns out that optimists were overconfident about their ability to control the elusive light, and depressed people were pretty accurate in how much control of the light they felt the switch actually had. 

@Kyle AshmusNumbers look optimistic however based on the back story and your calculations this looks like a good one for you and worthy of looking into

I'm looking for help to assess a single family 3b2b home as investment property (built at 1900, renovated 2017).The asking price is 139900, For monthly rent I'm analyzing 3 scenarios: based on what I see on zillow the typical rent for 3b2b with good condition is mostly $1450-$1500, with some asking $1700, so I ran 3 reports with $1200 (worst), $1450 (expect), $1600(optimistic) scenarios.I assume repart,capEx,vacant 10% each, and management fee 11%.Are the assumptions reasonable?

In MF if they are assuming flat or lower cap rates on exit, they are overly optimistic.

Digging in to find those out should help.If you go back and realize that your estimates were off or you were too optimistic about costs or revenues, then maybe it is time to get out and let these properties become someone else’s heartache.
