Let the realtor and property manager know you want to buy rental properties in the school district of good to great public elementary schools around you - Medlock Bridge, Simpson, Summit Hill, etc. and purchase as many properties as you can leverage with the $100K (put down as little as possible).  

What's interesting about Ivy City is that the residents there don't seemed motivated to petition the District for better forms of access to public transportation.

I think the key is to focus on areas with good school districts, rehab entry level houses. 

Essentially buy new construction in 6 or greater ranked school districts in solid areas (path to progress) focusing on renters moving out of apts.  

The Canyon Creek area is basically cut in half by the school districts.

Ill add another factor to consider and that is this:Which properties will appreciate faster (thinking about school districts, demographics, jobs in each area etc) and which properties will you be able to perhaps improve some and increase the rents?

In Texas, though, we have picked brick houses (to avoid messing about with painting or repairing siding), 3/2 houses in nice school districts and... in the oil patch, and near a military base. 

If you're in a B area this may not be an issue but in lower rent districts this can make your rent collection more of a headache. 

The school district, as many people chose their homes, based on which school their child will then go to.

The school district (12) is rated as one of the best in the country - house prices are very stable; even during the recession.
