ESTIMATED VALUE

What N705SP might be worth

Rough range$120K to $480K

A rough range for a 1985 piston twin, with a middle of about $240K. From manufacturer-published new prices of comparable piston twins, depreciated for age. It is not an appraisal and knows nothing about N705SP itself: total time, engines, condition, equipment and the logbooks move the price of any one aircraft.
