Is this a deal? wholesale

[Auspria Wade]

I recently sent out my first campaign letters.  I received my first phone call today.  It is a lady who owns a property with a tenant and wants to get rid of of the house.  She told me she had a lot going on in her life right now and didn't have time to deal with the house.

The ARV is around 80,000 per zillow and around $65,000 on realtor.com. She threw out $40,000 as a figure but then took it back because she didn't know how much the property is really worth because she bought it as a short sale a few years ago.

I spoke to someone and they told me that I should offer $20,000.  This seems low.

All advice welcome as this could be my first deal.
