Is that still the case that only W9s need to be collected from contractors that you paid with cash/checks?

Look at your credit and if it has improved applied for a loan on  a muti-family home, so you can collect the rent and pay the loan, if unable to sell. 2.

In this step your notices from step 2 will show the court good faith towards notifying the former owners. 

Also, some places like CA and MD have very tenant "friendly" laws (against the landlord in some cases) so make sure that you know the laws and if possible, have an attorney or service to collect overdue rent and/or eviction as needed. 

If they are billed separately, the charges may fall into Fair Debt Collection Practices Act laws.

Although I am outside of my comfort zone and feel like an absolute tool (I'm lost and that's uncomfortable), my faith, drive, and want to achieve my family and life goals continues to motivate me to get outside of my comfort zone and push for continuous improvement.  

@Pamela M. how collectible is this person?

I've been pretty pedestrian just collecting AmEx points and moving them to Delta.  

Collection is on time, they address repairs promptly, leases get renewed and increased based on market research.

To answer the title of your post, selling fsbo can be a good idea if:- you have experience selling RE- you price the home to sell- you have systems in place to collect inquiries and facilitate showings i.e. call center/email/google forms for screening inquiries, showing agent, lockbox, security alarm, etc. - you have dozens of local agents who can market the property for you and bring you a buyer- you are listing in a desirable area with low-inventory - you are not in a rush to sell
