Please see my thoughts below in bold.

It’s incredibly rare statistically but you feel pressure to participate because everyone does, and “what if” lightening actually strikes.

Hard to say you "changed your mind" when your behavior doesn't change isn't it :)Be bold Be thorough and use your professionals and their accumulated wisdom.  

Do you have statistical data or experience to back up the lower numbers?

I don't know the building unit count statistic influx, but I can't believe it is anywhere close to the net migration (supply/demand fundamentals).

There have been some pretty bold claims on this thread.

Once the paperwork is submitted and inspection takes place, we write up the lease which the tenant signs along with a bit of paperwork from the Section 8 office, and we schedule a move in.In our experience, tenants who hold vouchers are statistically just as good as any other tenant.  

Can't help but think of the expression,"Fortune favors the bold" in this case.Hint, hint...I'd love your experience to be one of the next ones on the BiggerPockets podcasts. :)

If this was your first flip, I applaud the boldness of tackling a 4 unit! 

Boards often have the mindset of "keep the maintenance fees low", instead of putting forth the effort to properly plan for statistically predictable major repairs and replacements.
