There should be a multiple listing service in your area.

I would suggest getting a real estate agent. They are technically free, but they get paid out of the sale. You don't get money from the government but you don't have to pay some taxes. You will also get a tax break for owning.
BTW my wife and I just signed our papers on June 15th so we are now home owners.
