@Joel Bayer- I stopped using the BRRRR calculator a while ago because it doesn't handle complicated financing scenarios like this well. 

I'm getting to the point where I have a good chunk saved and am wondering what guidelines people follow to know when they can start tapering off the contributions or stop them altogether.What rules of thumb are out there that people use?

No plans to stop. 

Two weeks later I stopped by the unit (was passing by and decided to take a look) and found that someone was using the shower and leaving food and clothes in the house with visible intent to return.

@Bruce Schussler   I am always suggest my borrowers stop at 60% loan to value when utilizing this strategy.  60% is the loan to value where the loan would qualify for the best possible rate.

Why would they stop if nobody sues or gets the police involved?

People told us that the streets weren't safe at night, and I can confirm that because we had a trailer stolen from a parking lot overnight!

Just want a software that does a great job handling the overall operations smoothly, a one-stop-shop for all PM needs. 

I got all sorts of calls, usually some were just curious, some were angry, every month someone called the police, the BBB and one time even the FBI on me, because the term "cash offer"" seemed suspicious to them - drug money LOL A place officer called me on behalf of a resident asking me to stop mailing them, to which I replied: sure whats their address and he said: he would not give me that information.. 

I would be beyond humiliated to come to the office that many times in a row, not caring about bothering someone or stopping them from what they are doing to have them walk their fat pregnant butt to their home to let them in all because they dont care about anyones time but their own!
