If I were starting from scratch on both bathrooms, I probably would not have chosen tile due to cost  and demographic on this home.

A simple Google search on zip code will give you a number of sites to look at the demographics of a neighborhood, including the renter/owner make-up, crime statistics, schools, etc.

@Jake Hemrick  basic comments are 500 dollar houses are priced that way for a reason.. and if the locals have not snagged them then they are probably beyond salvage physically and demographically.

Ask a few questions about NOI, differed maintenence, and demographics to establish yourself as someone who knows what they are talking about. 

I could see buy and holds that target the young professional but once you get into the growing family demographic, you run into the poor school system as a potential issue.  

Then the old housing stock becomes "substandard" and for lower-end demographics.

To take it a step further you can research zip code demographics, local crime data, schools and education, and job growth. 

The area demographics ( median income level, population 1,3,5 mile radius, daily traffic count on the side of the road your property is on, how close it is to a corner and red light access with sight lines all play factors in tenant demand for the dirt).       

Beyond price though, per unit cost, age, HOA no HOA, surrounding population, political demographic, etc.

check out the book "Demographic cliff" by Harvey Dent, he explains clearly why cash is king in the next 5 yearsThe times in my life where I got into trouble were when I over invested and left myself with a small cash position - then life seems to happen.
