cashman,
You have to look at the interest that the money you would spend on the house would be earning. Run the numbers. Even after taxes, I think the interest on the amount of money it would take to buy a house that rents for $2700/month is going to earn at least $100K in four years. So, you are not really spending $130K to wait, you are spending about $30K to wait. Trust me, a house that sells for $700K now is goint to sell for a lot less than $670K 4 years from now.
