How can we keep our DTI low and maximizing our buying power?

I have no children and no debt except my primary mortgage which is very low.  

It fit most of our criteria, so we offered low and got it.

PM is hard work and a very low margin business. 

I personally hung my license at eXp because of the low fees, and good splits and the team I joined when starting out was here so I had to.

I normally suggest being right smack dab in the middle with a low risk B class asset.   

I keep hearing that it makes sense to focus on markets that have strong economic and population growth, but there's really no overlap between population growth, economic growth, low prices, and low taxes.So my question really is, what's the best way to get out of this?

A low price would be important but not too low (so that it raises buyer concerns) and ideally a brand that is well known and liked by MH buyers. 

Heck, I run it and print it out for a seller and include it with my PA as justification to my #'s that I am not just low-balling em but here is the facts, I'm gonna have this n that price coming up. 

I'm planning on quitting soon, moving back home for a little and taking a few months in between my next job to pursue my first investment.My rough idea for an investing strategy is:  long-term, not necessarily looking for high cashflow (just want to start building equity), quality deals > amt. of doors, Class A/B neighborhoods mainly for low vacancy.
