The range in percentage is 66% to 118% of list over the same 12 month period. So the percentage will depend on how well priced the property is to begin with and how :hot" it is in the market.
Many Sellers will give some price concession for cash. But unless they are distressed and need a quick sale, it may not be a large concession.
I am a local agent (although originally from Massachusetts!) and if I can assist in any way, please call or email.

There is no set percentage. The list price may be high, low, or right at current market value. The best way to know what you should offer is to have your Realtor do a Comparative Market Analysis (CMA) on the property using SOLD comps within a 1 mile radius of the property (the closer, the better) that have SOLD within the last 3 months. This will give you current market price and this is what you should base your offer on - not on list price.
