I am of course starting at the seller's numbers but never really stay on those for too long... too much optimism baked in... but alas, such is the game we play.For POH's, what sort of expense ratio should be a reasonable estimate for modeling out realistic assumptions? 

Never look at just one expense category, like taxes, to determine if it is a good idea to keep the asset.Always look at the overall underwriting to see if the investment would make sense if you were starting with a fresh 80% LTV loan. 

My guess is something like the swiss national bank, along with their 80 billion in us stock purchases, went shopping for some real estate with their freshly printed francs.

After moving back here to GA I am convinced it is time for me to join the ranks of the investors.I am very knowledgeable on many things real estate but completely fresh to the idea of investing.

Is this a good plan or is it half baked?

I've talked to a few people about doing rentals and most of their responses are about the same "start of with a cheaper small house, rent it out and gradually work towards getting more lots and then work bigger towards dupleces and so on" I need direction for learning tools I really am starting fresh, I don't have knowledge really at all on market what factors that are in play when going to buy a house or renting it out or anything like that.

Not sure how to offer "fresh" items like milk or bakery muffins if I can't have them in a supply closet for the maids to put out after a cleaning...I am putting a Keurig in and planning to offer a variety of coffee, tea, and hot cocoa pods and some shelf-stable half and half or creamers.

To them, it might be more about you denying them their essential humanity, treating them like troglodytes fresh from a life underground.

@Chirag Shah Real Estate's like baking a pie. 

I also own a 9000+ piece of property zoned for multifamily, that I'd planned to develop into family-sized housing affordable to middle income folks (the affordability was going to be baked into the architectural design).
