[pianotech] written appraisal

[Gary]

I've been contacted to do a written appraisal.  I have done my research 
and have a good idea of what the piano is worth.  Now, how do I word it 
on paper?
Certainly something like 'I have determined Steinway Model M serial 
number XXXX is worth $XXX.XX' won't suffice.  Any ideas?
thanks,
