However I'm unclear how such a change will affect the rentals, especially since I have read that rentals should not be held in an S or C corp (my entity would still be an LLC, with an S-corp tax designation). 

The 50% rule wasn't designed for commercial properties but even their there are crude guidelines as to what works.

I realized after reading a book "Rich Dad Poor Dad", that I should really concentrate my efforts on unearned income and feel real estate is a great vehicle for passive income.  

Matt,Does your $130/sf cost for new construction include soft costs (design, permit, ect)?

especially vacuum up the precipitate after having just added concentrated chlorine (hypo) *fumes*

What helped me out is to only concentrate on one thing at a time.  

Design a life that gives you freedom to learn, grow, and spend time doing what gives you the most satisfaction!  

Hi folks,I'm designing my website and thinking of ways to set myself apart from the rest.

The other issue is that my HVAC guy said the AC unit (in basement) is too small (3 ton) for the 3000 sqft house per code and need to be replaced but my house inspector said the size of the A/C has more to do with design and planning. 

Even for a building, there is a process of public interest design.
