Anyone that is interested in this topic would probably enojoy this website:
Best Places You can compare two cities or just view a city's profile. You can enter what your yearly salary is and it will calculate what you would need to make in a different city to maintain the same standard of living. (Considering the different costs-of-living) You can compare many different demographics of a city, including the average home cost, property taxes, and property appreciation rates. It also compares your results with the nation average.
Note: This is not intended to be a "plug". The site is not mine and I am in no way affiliated with it. I use it for work and have founnd it extreamly useful for comparing such things as those that are being discussed on this thread.
