Investment Calculations

[Andrew Patocchi]

One major thing I need to know is if a house is a good investment or not. I'm good with math, but I need a formula to work with. Can someone help me with this? As far as the price of the house - (general contractor fix up costs + appraisal cost + interest rate on loan + interest I have to pay to a real estate agent to resell the house). I'm sure there's a better formula than that and a few things I'm missing. Thanks for the help
