A buyer or buyer’s agent must present you with a valid written contract,
called an offer, to initiate the purchase.

Carefully take into consideration the contract as a whole and pay attention to individual clauses.
You can accept, deny or make a counter-offer in response. You may wish to consult with an attorney before accepting a contract, as you the contact is legally binding and you want to make sure you thoroughly understand all of the clauses in the contract that you are agreeing to.
Ask questions to make sure you understand the terms and all of the mandatory and voluntary disclosure statements.
The offer will require a response within a specified timeframe. Make sure to allow for as much time as you deem necessary. You don’t have to agree to the timeframe you are offered. It is negotiable. If other offers come in, you will want an opportunity to review them too.
