So far I have check TransUnion smartmove which only does based on self reported income, but I am looking for verification from the employer itself.. 

Based on my research, it seems this company is owned by Larry Anderson.

Very involved in the REI community here, sponsors part of the REI Central meetup each month, works with a large portion of the investor base here.

And based on my business, and from what I am seeing with market activity, it is still very much a sellers market for those type of properties so many investors don't seem concerned about these proposed regulations.  

However, typically, property taxes are based on the assessed value of the property and the applicable tax rate.In your example, it seems you're referring to the timing of payments rather than the calculation of the tax itself.

even with higher rents once you calculate in the taxes, insurance and PITI based on the price its little to No cash flow.

i would imagine you could get away with a little less in your area based on facts rents are higher. 

I am based in Pensacola, FL and looking to purchase a duplex for the purpose of house hacking to get my feet wet in the REI game.

If you move away from that road and come closer to base or near the hospital, those would be great areas to rent in.
