It depends.
What's your net worth? How much are you going to put down? How much of your monthly income would be going towards servicing this mortgage? Are you single or are you splitting expenses with someone? Are interest rates/prices high or low right now?
I would say most people cannot reasonably buy a house until their mid-late thirties. If you have a good job and save a lot, you can accomplish it by your early thirties. It's unlikely that you will be in a good position to purchase a house in your twenties unless you get lucky, but even then, wanting to be tied down to a house in your twenties vs renting is up to personal preference. There is some advantage to being able to move around early in your career.
