@Harry Wiggins - There is no right or wrong answer to that question; however, many factors to consider - just a few of which are...

Good deal & good manager are key factors.

This and other factors will begin to open doors.At minimum, if you can "pay yourself" or save one side of the transaction commission, that is not bad at all. 

After that fifth year it is infinite (not completely true considering all factors, but approximately).

RISK Tolerance factor.

As for any other tax implications, I'm not factoring in the depreciation recapture for the past 18 months, but I don't believe that to be too significant. 

assuming your numbers are right, and there is demand in your area, factor that in. 

If I wanted to allow an attendant to pick up cash, my change machine reports the cash inserted so I can easily tell if im being robbed by someone, and the knowledge of this I imagine would be enough to deter sometime from what is a very flexible and convenient job.the trick is if you can buy the laundromat without a drop off service, meaning it's not factored into the price, then you open one up (which is easy), then you can really make the ROI explode.

I saw 203 as an interesting way to minimize my initial investment on a multifamily rental property but perhaps i'll need to consider a different option Reliability is another huge factor. 

There are a lot of factors to consider and every owner should be monitoring quarterly to seek what the best decision is for investor returns.
