Help - sellers memory is poor. Should I give up?

[Heather Carrow]

Hi all! 

I have a solid lead that came in...

Seller is an older landlord. She is tired of renting out to bad tenants and has two properties that she wants to offload. She was ok with my offer and is interested in seller financing - she owns both properties free and clear. I found her on Reiapro and it says that she is the only one on the deed. 

Here's my problem: She can't remember anything. She keeps asking me the same questions over and over. She doesn't even have a key to the property right now and doesn't know anyone with a key because the previous tenants left without returning it (not sure why she doesn't have multiples). Should I just give up on this lead and move to the next? I don't know how to make it work with her memory. 

What would you do?

Thanks!!
