Before learning this, my calculations showed it would cash flow $240 after expenses, but now it will take an additional $10-15K to fix and install these features.

I own a business checking account to manage rental income.

Working around people isn't a big deal; most addition and major systems work happens with people still living there.

- Do they provide a Perpetual Cost Segregation Evergreen Annual Review to find annual expenses from dispositions, additions, favorable changes in tax laws while also using the changes to drive lower insurance and property tax premium?

Do you have all rental income coming in one LLC acocunt?

About a month later I get a call from him letting me know he hasn’t received his income distribution for the month yet.  

In addition are utilities usually paid by tenants?

Four, I'd like to know any additional information that will be helpful. 

Take your gross rental income and subtract it by your PITI and thats your cash flow.

HOWEVER, want to avoid/minimize setting up a new company and filing additional LLC and other related documents (want to avoid extra work additional docs would create).
