It was mostly due to my day job income and low cost of living over a long period of time; however, real estate accounts for about 50% of our income through a small portfolio of short, mid, and long term rentals. 

@Mary Jay this is a question about ACCURACY in accounting. 

if you have an LLC and both properties are under it, you just need 1 operating account.If both are under your personal, 1 bank account specifically for the rental is enough for operating.Security Deposits should always be a separate account altogether.

You can still get positive cash flow even accounting for a PM - tons of my clients do as well!

This absolutely sucks, they should be held accountable.

Acquisition people, asset managers, finance/accounting roles are all needed to run properties, even if the property management is outsourced.  

Expect to see more brokerages reduce their fees for listing real estate as they move towards fee models that not only recognizes but accounts for the role technology plays.

Not sexy as Lexington but bank account is the ultimate measure of success

It is important to take into account the future of your investment.

You could also add cash to your exchange account to reduce the debt replacement if you wanted.
