Truly, it is hard to estimate without knowing more about the property one would consider selling, but as stated, properties that say they are sold in 3 days, 20 days or even 200 days may have been on the market under different MLS numbers several times due to relisting. Also, the same 3 criteria guide how soon a cabin may sell-price, condition and location. Creekfront or mountain view may sell before a wooded property. However, some people seeking solitude may want a small rustic cabin in the woods versus having drive drive up a steep gravel road to get a great view. Right now with foreclosures in the mix, price may be the driving factor. Recent examples of sales since Jan 1,2010 indicat a range of 4 days - 511 days. The former is an older 2/1 on the shores of Fightingtown Creek and the latter is a 2006 2/2 w/full basement.
both were listed between 176.000 and 179,000 and both sold for 20,000 less than asking - for cash.
Your best bet is to select a realtor, descrive your specific property and have a Comparative Market Analysis(CMA) completed to compare your location and condition to arrive at a price range. The CMA will give you Days on Market information on the listed and sold comparables plus an average for each category. Good luck.
