The other market I'm interested in is Dayton, Ohio.

Based on your experience, in general, what is the rational or the steps in getting into a new market.

Initially we were set on purchasing a Primary Residence again, single family or townhome within reach of my sons school and continuing life as usual, but feel like we are slightly priced out of the market we want and areas we need to live. 

But I have read many topics on here, many investors facing difficulties with BRRRR now as the market is “not right” which make me have to think again about this strategy. (70% rule still working for this market?)

Lower rates, more buyers in the market, more competition.

Its all what the market will bear .  

Nashville is a hot market for Rentals currently and it seems like that won't change anytime soon, and I've noticed that people are renting in Columbia and Madison quite frequently.

Learn the basics of financials in RE, build a strong team on the ground, understand the ins and outs of RE and what market your in, understand how to actually flip the home and what strategy you are doing (Highly recommend the BRRR) as holding homes is where the money is made.REAL ESTATE IS NOT EASY!!!

Interior and exterior renovations and improved management plan in order to increase rents closer to market and mitigate expenses.

They collect your rent, apply late fees,  deposit your monies into your bank account, market your properties, track expenses, screen your tenants, etc for just a few dollars a month per door.
