It appears you have access to these CCIM courses. 

Of course, you can hire a local inspector to confirm work is done before final payment, but that all requires some pretty decent process management.

I am guessing they can of course sell it off subsequently if it underperforms.The proof of the pudding is in their sustained payouts and capital appreciation.

They are inexpensive but you will get low intent sellers that youwill need to filter and nurture.Irecommend finding a good guru course and sticking to it, partnering with another investor/or working for one, or have someone on hand that is knowledgeable that you can pester :)
