Should I mail a offer or wait and call back in 2 weeks

[Rob Grove]

I got my first call back Saturday from some DM I sent out from Driving for Dollars. It was an older gal, 87 to be exact,  looking at how the process works. She said probably spring time. I tried numerous times to get out to the house. Anyways we talked about some other stuff for awhile, building report. 

My question is:

do I mail an offer or call her in two weeks to follow up? She claimed she got a few mailers before. She did throw a number out there but it was close close to retail. 

Thanks in advance.
