It all depends on how much rent would be needed to get something comparable to that $500K home. I am of the belief that it is far better to own one's detached house than to rent one, if only for the simple fact that the home can be leveraged at a lower interest rate than the reservation return than the landlord would demand. Also, the selection in homes that one could buy is far more extensive than the homes that one could rent.
Now, if by saying "rent", you mean renting something that would not be comparable (e.g., an apartment), then renting is far better financially speaking - but of course, that would be at the expense of having a lower standard of living.
