With all of that in mind and considering the area and the applicability of the comparisons, you will be close on the rest you can get.If you want to talk more details, message me. 

My company has non real estate (automotive related) operations in CHA/ATL/DFW/TPA/NSH/PHX, but I have family in Nashville and have grown to love Florida in my travels.  As a 1st time investor, would I be better off fo...

Would have to look at comps again to see the direct comparison.

Got a new one in Sept and almost half my payment is going towards principle already.So this isn't a which is better comparison, it's a how do I get a 30yr loan with a partner question. 

The total number of liens dropped again in comparison to previous years.

Lets compare Memphis to lets say Denver...Memphis Avg Price = $118,467 Avg Rent = $10,906 Maint can CapEx = $1,635 (fixed since heater costs the same in Memphis as it does in Denver as you are saying...)All other expenses = 40% of gross rent = $4,362 (I put expenses at 40% just at random and have the 40% fixed for Denver as well)NOI = $4,909CAP Rate = 4.1%Denver Avg Price = $364,400 Avg Rent = $16,932Maint can CapEx = $1,635All other expenses = 40% of gross rent = $6,772NOI = $8525CAP Rate = 2.3%So it looks like even with you stating that maintenance and cap ex-numbers cost the same from market to market higher rent to value markets do reflect better cash flow invest ability...by nearly being twice as lucrative in terms of cap rate vs cap rate comparison...

So I did side by side comparisons in 5 different homes and the case study showed basically the same test results. 

Maybe I need to be more specific in my question, lets say I'm going for the BRRRR strategy how different it will be from getting an Home-equity Loan instead of Refinance, talking about time, hassle and amount of capital that I can get back.Thanks @Ron Harris I did a little of research and though about getting a HELOC too maybe I should add that option into the comparison too.

This is not a good comparison to go off of. 

The existing mortgage will probably save me over $30k in comparison with my new terms factoring in the remaining maturity with the existing financing and the rate I would pay with a similar maturity.3.
