I remind these people that I appreciate their concern, but i've done my homework and am prepared for the worst case scenario so I'm comfortable with the risk, not much they can say to that.  

Thanks for the reminder.

Jessica, PM me, I understand more than you think I might, you remind me of "family" searching for answers.

Excellent reminder for all, thank you.I have a contract with a fire protection company to test and maintain detectors, as well as maintain/recharge/replace fire extinguishers.  

Also this reminds me of a previous article I read on BP.

Which reminds me.

As Charles sort of suggested, there's probably some sort of economics-based differential equations that could be used to model return vs risk vs time in various investment activities.While it probably wouldn't be useful in real life (not sure you could tune the inputs well-enough to be meaningful), you could probably play around with various inputs to get a feeling for their sensitivities to one another.If I were smarter, I'd probably be able to apply some of the utility modeling work I used to do as a poker player to real estate investing...Which actually reminds me that I've been meaning to start a really geek thread on a related subject...a bit off the topic (or maybe not), but if you've studied card counting in blackjack or were ever a geek poker player, you may be familiar with the Kelly Criterion...I've recently started thinking about whether there is a way to apply the concept to portfolio real estate investing:http://en.wikipedia.org/wiki/Kelly_criterion

Good job, this reminds me of homes that I have built from the ground up a few years ago.

This probably has something to do with the high rate of "no shows" after the 1 hour reminder phone call.

Feel free to remind me.
