Just don't forget to factor in sales expenses and taxes on short-term gains.  

There are many factors that will enable you to do this including how much money you have to put down and how much your property will command in rent.  

Rate is dependent on various factors (e.g. length of loan)

Employment growth, Corporate expansion, Job diversity and wage growth will be several factors that will impact the direction of rents.  

One factor that people in a 1031 don't realize is that 45 day period moves extremely fast.10. 

Let us just assume that it looks good, not average, and the wow factor is the living room that has a tile/stone fireplace on it.

With that said, what are the biggest factors you look for when making a purchase?

Plus I factored in your insurance MH expense and not the income so you can get technical but it really does not have much going for it especially with the market ( from the little we know) . 

Am I missing on any other key deciding factors?

General population, school population and employment in the area are factors I would look at.
