Maybe self manage when you have just one, and once you have proof of concept and want to convert all the units, then get a property manager?

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.

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

I don't have experience with the Detroit Land Bank, but generally land banks are pretty reliable, but...they are low money buys (from $1 to $1,000) that require you to show proof of funds for the rehab.

And STRs really help because you don't have the large dings that long term rentals have - i.e tenants damaging the property to where you have huge make ready costs (the str insurance covers that), no collections or evictions issues. 

It’s also important to remember that allowing partial payments without a plan can set a bad precedent, so it’s best to handle this firmly but professionally.For the future, collecting the first month’s rent in full before move-in can help avoid situations like this.

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

I'm basically here to make connections and collect information.

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.
