You need an income that meets three requirements:Rents increase faster than inflation to offset constantly rising prices.It must be reliable; it continues even during economic downturns.It must last throughout your lifetime.These are all long-term requirements, so the current interest rates are not the major issue.

“Broker” is a legal term that often requires standardized coursework and a state license. 

I have a separate interest bearing account for security deposits as required by my state laws.

I'd start by giving all residents the required notice (usually 24 hours) and go inspect the units as quickly as you can. 

Not to mention staff, I’d check on the number required to stay up to ratio throughout the day, night ratio is likely lower than day ratio.

One of the biggest challenges for everyone involved is being on the same page about the actual time required for maintenance.DIY landlords rarely properly track their time when it comes to property management in general - tracking their true time invested in maintenance is where they perform the worst.Investors that hire PMCs are rarely any better at understanding the true amount of time maintenance takes.

Quote from @Kathy Grossart: Can a non-accredited investor in an already established SDIRA, within a 506(b) multi-family syndication, do a 1031 exchange to another syndicated property (with same operators), if the new 506(c) offering required investors to be accredited, and the investor is not? 

I got an email today that the BOI requirement was on hold again since the fifth circuit reinstated the injunction today.

As for non-bank loans, I'm familiar with a loan program that provides 100% financing, but it requires a minimum 650 credit score and proof of funds covering 12 months of interest.

This requires vetting their claims by reviewing EDGAR filings, property records, court records, Secretary of State filings and communicating with those who know more like city government, a more experienced investor, etc.
