Based upon this I would look at an actual dollar amount, not percentage that: 1) enables you to live in a safe neighborhood and decent schools district, is modest in size and fixtures, and has payments sufficiently small that you are still able to invest at least 10-20% (or whatever your target is) of your income. 

Highly - Highly dependent on school districts that have strong STEM programs.Goodluck fellow BP REI.

Something short and simple. 3 bedroom, 2 bath duplex for rent in great school district!

Lay the numbers out, so they understand why the profit margin wouldn’t be enough.Similarly, if there are other reasons, like high crime areas or poor school districts, let them know.

I'd FOIA some of the local city governments/school districts/etc... to see what real estate they are selling and ask if any of them already have cell towers on them. 

School districts are average and household income is above average compared to Ohio averages.

In west coast most home owners filled the pool with dirt as local water district on and off for years to make water fill difficult and expensive.  

What are some strong employment / good school district markets that are generating positive cash flow?

Waterville Estates (in Campton and Thornton) is good for rentals because they have night skiing and a great rec center with pools etc but the property taxes are TWICE those of either town because they're a 'village district', which adds it's own taxes to the town tax - it may still work numbers-wise, but worth knowing about nonetheless.

Anyways, I'll check with the local appraisal district information and there's no phone number or name or other address to the owner.
