Before the first offer even comes in, you should have in mind, how low you'll go on price, what conditions you'll accept and what terms would be agreeable. Then, when an offer comes in, you have a set of criteria by which to evaluate it.
Scrutinize all of the details, chattels, closing date, conditions, address and description of your property, provisions and deposit.
You and us will thoroughly go over every detail. If there's anything you don't understand, ask!
