help me get the current market value and the ARV? (second opinon)

[David Daniels]

Hello, I came across this ARV which I think is outrageously high (which is 525k), compare to what the asking price was (which is 290k), I done my diligent on the property and ran several comp and I came with ARV of 350 max (keep in mind it could possible sell for a little more) but i think she should sell somewhere around 240k -245k (keep in mind i never factor in my repair cost in yet because haven't seen the place in person) they place look like its in pretty good condition , it just needs an up to date appeal (Ill show pictures) One sec) which i think would be about 20 k judging from the picture. Now she figured 140k est in rehab can boost the arv from 290 k to 525k...How did she get this? the only house on my comp that sold close to that 525 k was a house a couple mile away and it was double in SF. If im going to try and hit that 525k value mark, im thinking i would have to gut out the whole house, and upgrade the whole entire house, that would be about 140k in rehab. How did she come up with that outrageous number?? and can you figure out a quick comp on the property of what you think it is worth as is and then the ARV?? Here picture below
