Measure a refrigerator multiple times before ordering, lol.

I was aiming for 5 overtime but I don’t know if this really necessary?

You can contact a local flooring company or go to Home Depot and see what general cost per sq foot are for carpet, vinyl plank, etc and take your room measurements from the MLS listing (or bring a tape measure on the showing) and go to town.

People can look at real estate on a 3-D graph measured in time and money and risk.With that in mind, low time (required) and low risk, you find the products you listed in your post: REITs and RE index funds. 

I would aim for areas OTP Atlanta ranging all the way from Stone Mountain/ Lithonia, through the south all the way to the airport.

If you're planning on buy and hold, aim for a great investment in a great market from the beginning, and only plan to sell if you find a better return on equity and can 1031 out.

I think I'm aiming too high on the rents, but it will be interesting to dig deeper into this one.

If you have any outlets, faucets or HVAC vents in the wall, you will know right away.If it is NOT bearing and there are no HVAC, plumbing or electric runs in it, download a cheap floor plan app, measure the room as it is sits, print out the plans and highlight the wall getting removed.  

We need someone to come in and take measurements too.

Such a broad reading of the statute and the term other measures in particular, would authorize actions with few, if any, limitations - tantamount to a general federal police power.
