The school systems in PG county are not the best BUT keep in mind that some people don't have an alternatives, or they want to live close to family, or they like what the are has to offer (art district, coffee shops, proximity to DC, 295, 50, or 495) The majority of the demographic in Mt Rainier, Hyattsville, Riverdale have little options but to accept sub standard school those who aren't are paying for private schools (DeMatha, Seaton, etc.) or testing into Rosevelt. 

Now you can invest a smaller amount across a range of projects thanks to the advent of real estate crowdfunding.Now you can go online, research both developers and crowdfunding platforms, and invest in exactly the kind of real estate you want to buy, but instead of putting all your eggs in one basket,  you can invest a smaller amount in projects in diverse geographical locations, with different demographics, and operated by different professional development companies. 

In market areas with excellent outlook (i.e. good demographics, high income, growing economy) investors will bid up properties (i.e. offering more) because they expect rents will increase therefore NOI will increase.

I would narrow down which of these markets you want to focus on through demographics, then meet with people from those areas, as there are submitting markets that just don't show up through demographics.

If it is an area that supports that type of demographic, then yes, 1 bedroom units can be great. 

What demographic is the most risk?

@Mariah Klemp there’s some interesting data on credit usage by demographic sector.

Given the range, I am looking in cities that are more affordable but still appealing characteristics/demographics like Columbus, Cleveland, Indy, KC, Memphis, etc.

Neighborhood, house composition, rent and comparable sales trends, demographic that is likely to rent said house, etc.
