Do you have any tips for writing a purchase offer? I know I need to work on it myself and make the decisions and not my agent, but are there things I should keep in mind while looking at a home to write in the offer later?

Thats a great question and one that often leads to issues. An poorly written purchase offer can lead to the seller backing out, or other issues you don't anticipate. Some of the key things to pay attention to are buying the right form, picking a price, making a deposit, disclosing your down payment, naming financing terms, addressing possession date, including contingencies, who pays fees, requesting reports and a clear offer expiration. By making sure you have covered all the points which can be interpreted wrong you will save yourself fighting over the possession date or trying to get out of the offer if the house comes back with a cockroach infestation.
