As others stated so well, it depends.
Here in FL, a bank owned single family home will sell 20% above listed price.
Here in FL, a bank controlled short sale may sell for list price but require a $100,000 cash payment in addition.
Here in FL, a 'move-in' ready home will sell 96 to 102% of list price.
Here in FL, a tired home can sell anywhere from 60 to 85% of list price.
Here in FL, a neglected or damaged home can sell from 20 to 60% of list price.
If you dump them all into one category, the data will not be applicable to the home you want to buy. It is similar to using national real estate statistics in a local real estate market. Only works by accident.
Best of success to you in buying your Sandwich home,
