We have a development coming up for approval with the county adding over 100 units bordering our small town and you can bet everyone that lives in our town is upset about it. in the end though, the planning commissions in our area tend to follow the letter of the law so to speak, so if there is nothing in ordinance barring it, they will approve, generally.

The building was partially renovated in poor taste.  

We gave The Real Estate CPA a shot because a virtual business model and their marketing here sold us, but had a very poor experience.

Majority of the houses are old and require frequent repairs in addition to a poor tenant base that can't pay on time and don't care about their credit.

And you can be a landlord that gets a very poor return because they haven't utilized their space well by changing the layout.
