AWC-C - this is a home for sale, under contract, however, the purchase is contingent upon the sale of the buyer's property. In this market, I generally advise my clients from taking these type of offers. However, in some cases , this can make sense.

The AWC-I is very common these days , as REO/ bank owned properties or 'short-sales' will still entertain offers while the bank is making a decision.

Be careful to look for these contingencies.

If you are a buyer, make sure your Realtor asks the listing broker if the home is Active with any contingencies so you know what is the best way for you to proceed with your offers.

If you are a seller, don't hesitate to use these contingencies, to protect yourself from questionable buyers and keep your home marketed actively for back-up offers.
