I would say I'm a cautious investor so I want to hedge my bet as much as possible.

I personally can not stand the sound of the floating floor, i have not found one yet that does not sound "hollow" when you walk on it. your best bet is glue down or nail down, you can buy 3/8" nail down flooring, and as mentioned by @Jon Graham  some of the engineered wood have a thick enough top layer to be able to re sand it, do your homework on that.

You are essentially betting on the US economy.Obviously, if you see another Mar 2009 scenario IN ANY MARKET, and develop conviction, go in with everything you have got :)

My reservation for Buildium is that it is a web-based system that I'm not too hot on.

Bet the winner hadn't seen the inside.

I'm not a betting man, but if I was I'd say they homeowner is trying to pull a fast one.

I read about them on the web, but am very skeptical.

I finally have phase one of my web site complete and am putting the URL on some of my marketing.

I haven't looked, but I bet there is one available here on BP.Finally, the AIA (American Institute of Architects) publishes guides you can purchase that give you all kinds of figures for calculating costs.  

I bet I regularly work 80+ hours a week right now and love every minute of it.
