Hi @Konstantinos Lembesis When Settling on a market develop some metrics that you can not only measure the market you are interested in but others that you havn't considered yet. 

Plenty of investors work the Atlanta market but the ROI is better in Huntsville and Atlanta is tenant friendly.

How true is this, and how could that affect my real estate strategy if I were to enter the Texas market as a Washington State resident?

Was it a specific moment or just a long-term goal?

My recommendation would be to choose potential markets - in several price points - that have strong rental demand and year-over-year rent increases and that also are in markets that are appreciating. 

Homes Are OverpricedHousing could be overvalued by anywhere from 10% to 35% based on how investors are actingThe stock market is pricing portfolios of American homes at a hefty discount to what houses are changing hands for in the open market.

Very interested in the Cleveland/Ohio market in addition to a few other cross-border cities closer to Toronto. 

I've received their rent roles (4,760/mth) but believe that the market value is about $6,600 to $8,100/month.

You would really want to do your own due diligence and probably fly to the market(s) you'd like to invest in.
