Theyre expensive, but you wont lose your home to foreclosure unless you move out, stop paying taxes/insurance, or fail to maintain it. 

Justin made posts here about how much "he spent" rehabbing units that wound up belonging to other people. 

Lots of DC area people on here.

Steady pay, you can learn how to manage property and deal with people, and you'll be licensed to handle sales on the side.

Generally larger commercial properties and shopping centers are easier to classify with hard and fast rules, but to the points above the residential areas really move very quickly and have way more nuance than most people care to admit.zip codes are generally way too large for my liking at least in my market to provide any kind of insights other than macro level economics but even then highways or rivers that cut through a zip code can end up with totally different trade areas.we can get pretty granular with cellphone data and with grocery center data to understand the trade areas and their true boundaries, but that kind of data pull is generally only cost effective for investors doing larger scale projects or developments, and honestly we still just end up getting on the ground and feeling it out, so I generally tell people that the money is better spent on a plane ticket and weekend trip in the area you are looking rather than any kind of "trade area" level data studies.and generally B class in 1 area means something different than another.

Proportional leverage (like 27% LTV) isn’t specifically required, but if you don’t reinvest the full amount or fail to replace debt, the difference will be taxed as boot.

Some people need 2% above the borrowing cost (8% cost of hELOC you gotta then make 10% + etc) and others will want to double their cost of capital or 200% so it depends.Everyone's going to give you their anecdotal experience or what their preferences are so its good to hear it all and determine your own.
