Give yourself an edge when making an offer on a house. Items you want included in the sale, such as window treatments, appliances or lighting fixtures.The amount of your earnest money deposit. Focus on three things: State your intentions, show that you have the financial means to make the purchase and make a personal appeal to the seller. A real estate purchase agreement is a legal contract. A good agent repping a buyer doesn't just write the offer, either. And the ones who just care about a transaction completing are not in the business very long. Our businesses are built on referrals. Like marriage, homebuying is one part love, one part legal transaction, and starts with a proposal. Write the seller's preferred closing date into the offer.
