@Derick JenningsRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

It is a BAD loan for most people.  

It seems to me that they all whether paid of free, will all have the same exact amount of houses because all the transactions are all public and so they seem to compete with each other based on the quality of the data of the houses, how up to date it is, and the user experience in configuring the how the layout is.

Let's look at your example of a roofer, assuming he owns the company.He has to pay for employees- they still get paid, even if they are not giving 100% effort.He has to pay his workers to go back for warranty work - effectively paying them to do the same job twice.He has to pay for equipment, even when it's not being used 100% of the time.- but the company he bought it from still gets paid.He has to pay for advertising, whether it works or not.- but the advertising company still gets paid.He has to pay for accounting services, payroll services, tax services, legal services, etc.- they all get paid whether he makes money or not.So, what's your point?

A full back office. 3 workbooks to use in the 40 hour cI get it just like any non certified or accredited  training.. not saying its bad. but its not a state license so not governed by any state and there is no NMLS registration required..

More open spaces around the city for people to get outside is never a bad thing.

Colors, quality of paint, how much prep needed, holes patches etc. 

Here's a https://www.irs.gov/businesses/cost-segregation-audit-technique-guide-chapter-4-principal-elements-of-a-quality-cost-segregation-study-and-report to the IRS website noting specific items that are included in the cost segregation study report. hmm, that website is a 404 error.  

I think you are just having bad luck with tenants on this one.
