Chris is right in saying that it is totally up to you. My honest professional opnion based on what you have said so far makes me think that owning a home might require you to look at your finances closely. If your current monthly rent is pushing your comfort level I'm not sure if owning a home would be a smart thing at this time. Just imagine if your car broke, and water heater broke. That would be $500 each on top of the mortage, insurance, and taxes.
If you currently are in a very comfotable situation, have at least about 3% for a downpayment saved up then you might be ready (provided your credit score is acceptable to a lender)
Sometimes telling seller's not to sell or buyer's not to buy seems odd, but it is the right thing to do. Best of luck!
