Purchase home

Here is my plan…

I’m looking to find a home from a motivated seller that has equity, make some minor changes and then sell it.

I find a home on a rehab web site that says no repairs needed, it’s currently occupied, and states the ARV is $330K. The owner is moving and they need to sell quickly! The asking price is $265K

First thing I do is go to zillow, $212 - $296 ($255 average)
BOA says Highest - $342 Lowest - $298 ($320 avarage)

There is a big difference in both of these. Who do you go buy?
What would you offer?

Would you have a home inspection done prior to purchase? Would you also not close on the house until the owners moved out?
