Currently I own 8 doors in RI and wanted to diversity and go to another part of the country to invest.

It's fairly close-in, has a tight-knit, diverse community with a strong neighborhood association, minutes from i84 and i205 as well as the Max lines to downtown Portland and Clackamas and median home values are low low $300s but there are still plenty of houses to be found <$300k. 

Hope this helps. btw: how are you contemplating two strategies so diverse?

Ohio has a diverse range of markets and properties for every budget.

There is a decent amount of product sitting in those markets but without the savings at which point many buyers would choose location and a little smaller home  There is such a diverse employment base and strong economy around Madison that it is hard to see what may cause a correction, not that it is impossible  Most of the townships in Dane county are Ag exclusive with somewhere between one building site for every 15-35 acres which puts a lot of pressure on existing inventory and helps to boost the appreciation and the more desirable the location, the better the appreciation  It is interesting to me that most of the builders are relatively local and there don’t appear to be any large national builders or even too many regional builders in this market from what I see.

I’m starting to think I need to buy an RV and travel through Colorado because it’s so beautiful and diverse . . .

Texas has four major markets that are very diverse from each other.

For as little of a state as Delaware is, the state is very diverse.

Anna, that's because it is not only a strong cash flow market but it also has a growing population, jobs, diverse economy and industry and MO is a landlord friendly state with relatively low property taxes. 

They also don't support the rent increases my other B- properties due because they are already at top of the market rents.On the other hand, my B- properties cash flow better (almost always above the one percent rule), rent faster, support more frequent rent increases, have less turnover and way less picky tenants.I wanted some diversity in location so I have about 4 B- properties to every 1 A property.
