It's natural to want to save money when you're making a purchase as large as a home. You want to buy the best home in the best neighborhood at the best price, and you may think the only way to accomplish your goals is to look for bargains. So instead of hiring a real estate agent, you scour the market for FSBOs, short sales, foreclosures, or homes that have been on the Internet too long.

While you're bargain-hunting, here are five things you should keep in mind:

Lowballing sellers doesn't work.

They don't waste time with low-ball offers that they find insulting. Just as you want the home you buy to appreciate in value, sellers purchased their homes as investments, too. They want to net as much as possible, because they took a financial risk and had the foresight to buy the home they chose.

This sense of entitlement -- that homes should only be sold at a profit - may cause them to overprice their homes or be less willing to negotiate. You'll feel the same way when it comes time for you to sell your home, so make your offer reasonably and respectfully. Show the comparables that led you to make the offer. Be open to compromise.

Other buyers are getting professional help.

Ninety percent of buyers use a real estate agent while you're spinning your wheels driving around neighborhoods and calling FSBO sellers who aren't home to take your call. Soon, you'll notice that the homes you're watching are going under contract with other buyers.
