market value?

[Tyler S.]

I have a house im going to look at and court records show that the property is worth 125000. My seller said it appraised at 168000 recently. He has made a lot of improvements to it. Should I take his word or go off of 125000? And if he is right about the 168000, how can i be sure he is telling the truth without using my own appraiser? My intentions are to wholesale the property.
