Shortly after I purchased a duplex and then a 4 unit and some more in that range before I bought an 8 unit.

So if affordability is the goal looking at wider range is something I would suggest. 

Yes, mainly looking in the $30k-$100k range (I know anything under $65k is a bigger project).

Yes, they are within a "normal" range.

I might add, your entering range to reap cap-x expenditures so this cash-flow is soon to be significantly depleted/off-set via those expenses. 

This was my first property, and while it's been a great learning experience, I made several mistakes along the way—ranging from choosing a realtor who was more focused on closing the deal than finding the right house, to having a poor inspection and overlooking issues hidden beneath the surface (literally).

Coming out of the 1031 I'll have about 620k to invest which means I am looking in the 1.5 to 2 million range if it matters.

I personally love the Cleveland market for its cash flow ranging from 10-18%.

Go with a smaller rental and you should be able to find something in that 300k to 350k price range.   

The menu offers Cuban favorites like tamales, empanadas, yucca fries, ceviche, and traditional entrees like mojo pork and whole fried snapper, with prices ranging from $12 to $95.
