So when doing the math…Do I consider the original 2006 down payment costs and years of primary residence as part of the calculus on current ROI/ Cash on Cash return, etc…or ONLY the numbers associated with the REFI in 2012 when I converted the primary residence to rental property? 

Can’t solve for one variable with too many other floating variables.Wow that reminds me of multivariable calculus...Anyway, stick to your principles.

Glad I don't need like business calculus or something crazy like that.

I went to 3 semesters and I have 2-3 close friends that I could see myself doing business with in the future, but I feel that I could meet more like minded people in a local BP meeting than in Calculus or History class..
