For example, you set up key word alerts. http://www.biggerpockets.com/alerts

You're lucky the property is not in worse condition and the guy is honest enough to admit his trangressions...so at least you have a tenant with a conscience.I'll just use one example to make my case....Daughter and her daughter are now residents who are not on the lease. 

Cali and New York City are good examples of terrible places for buy and hold.

It would be fantastic if other buy and holders that have gone through this transition could provide some examples of what's worked for them.Thank you!

For example, set up Twillio to work with Google Spreadsheets for a buddy.

For example, they'll agree with our financial analysis of a deal but say it's too skinny when it yields 30% to them.  

For example, the REIT will pay its "Advisor" (which itself is a separate LLC, wholly owned by Rich Uncles) an Acquisition Fee of 3% of the price of a property when it purchases a new property.

@Tim Shin I really like the BP calculator for back of the envelope high level estimate, but you're right that every property will have different expense ratios.For example - one of my rentals is a brick home, energy efficient with an older A/C unit.  

For example- you are current on the first mortgage but neglect to pay on the 2nd - and they foreclose without telling the 1st - even though they must make continue to make payments to the first to keep it current. 

For example, a local landlord here performs a monthly furnace filter change at one of his rentals.
