Water- Either check with neighbors, drill test well, or call me to Witch water to see if you have water on the ground. 

I’ve been starting my research by seeing what is being bought and what is on the market, and live nearby so would like to check out neighborhoods, but am wondering which neighborhoods I should invest in?

Charges them all for parking passes (on the lots I own), charges for pets, charges to empty the coin op laundry, charges for credit checks etc.  

If the tenants don’t leave by the deadline, your next step would be to check your state’s landlord-tenant laws to understand the eviction process.

Check out the federal rules as there is currently a ban in place for most foreigners to buy in Canada. 

I've seen investors succeed both ways.If you're looking at Ohio markets, I recommend checking Columbus OH. 

Check AirDNA for demand, pricing, etc.The Dekalb Board of Commissioners has proposed regulations for short-term rentals. https://engagedekalb.dekalbcountyga.gov/airbnb-dekalb-countyShort term rentals require you or your property manager to be hands-on and come with more risk.

Did you check with the county and make sure you can do a STR in that area?

So... do I still need to check PH level.?

I suspect a decent VA could access public records and build a mainling list for you  or check Property Radar and see if there software will do that for you..
