@Adam Briley is the duplex Class A property or Class B or C?

I think the class of property/tenant is also a factor on where people look for apartments.

., would you mind sharing what classes you had to take to learn how to install?

Aaron, the reason I do my own background checks is that I own c class apartments and prospective tenants do not want to pay for background checks.

Low slope roof on 1,200 sf starter home in working class neighborhood.It seems like the proper option is a TPO roof with and estimated lifespan of 20 years.It seem that the cheaper option is to replace the exsisting MSR roll roofing with the same again which has a 8 ish year lifespan.The price difference is $1,800.Do buyers know or care ?

Pick a solid B-Class suburban area.

Also, Sheboygan has the most middle class households of any metro area in this study: https://www.pewresearch.org/fact-tank/2018/09/06/the-american-middle-class-is-stable-in-size-but-losing-ground-financially-to-upper-income-families/.Happy hunting!

While there is some truth to that, I've found (as a Class C investor) that there are good tenants in every price range. 

Compared to our other portfolios I prefer Cleveland based on the yield, ability to operate, great selection across classes (A-F), changing national reputation, price points, and the fact that I simply like going there (I live in Boston). 

I was wondering if any seasoned fix and flip investors know of any classes, book, blogs, or anywhere I can get more informed on the process.
