ALL of my major problem tenants happened to have had a average (adults in the household) score below 625. 

Look, I have no idea who Eric is, what type of person he is but I will say after a quick search I saw that he did in fact sell his company for MAJOR $$$ and that he is active in Section 8, no idea if his course is good or garbage but still felt the urge to respond because I am so tired of hearing SCAMMER, find it online to EVERY SINGLE post asking about any course. anyone who actually sells their business and nets 110 mil is NOT going to dive into Section 8 or any real estate for that matter other than fine personal residences etc.. they retire and spend it.. so I dont think so.Plus section 8 is simply not complicated its run by the Sec 8 folks in each city.. nothing magical about that.. its a tough way to go being a section 8 landlord lots of drama.

I believe the appreciation has been great over the past couple of years and prices are lower than in major areas like Miami metroplex or Charlotte.

:Class A Properties:Cashflow vs Appreciation: Typically, 3-5 years for positive cashflow, but you get highest relative rent & value appreciation.Vacancy Est: Historically 10%, 5% the more recent norm.Tenant Pool: Majority will have FICO scores of 680+ (roughly 5% probability of default), zero evictions in last 7 years.Class B Properties:Cashflow vs Appreciation: Typically, 1-3 years for positive cashflow, decent amount of relative rent & value appreciation.Vacancy Est: Historically 10%, 5% should be applied only if proper research done to support.Tenant Pool: Majority will have FICO scores of 620-680 (around 10% probability of default), some blemishes, but should have no evictions in last 5 yearsClass C Properties:Cashflow vs Appreciation: Typically, immediate cashflow and at the lower end of relative rent & value appreciation.

@Harrison Jones  One of the major flaws in your perspective is that it is focused on cheap rent (driving rents down) not affordable housing.

I agree - plenty of affordable housing but you are not going to find it in a major city or a very desirable area.

@Derek Heinz you might be better off finding a major fixer-upper, getting a hard money loan (HML) to acquire it. 

Most often it's in free & clear properties but, in a high enough desire area like these, and with low enough mortgage balance, yup, some can 100% get enough on the sale to have it all make sense because as @Jay Hinrichs has pointed out that in these areas the majority value is in the land not the structures on the land. 

You MUST understand this as the suburbs are usually much nicer than the city.All of these challenges are why we have a map of Metro Detroit on our website with the cities in Macomb, Oakland and Wayne Counties listed, as well as 183 Neighborhoods in Detroit.The majority of the 48235 zip code is Class C, the question is, do you understand what that means?

The vast majority of people will not have these accounts, and the % that comes with them.
