Found two potential sellers, what would you do next?

[Marshall M.]

Sent out 50 hand written notes to out of state owners with properties in northern Virginia with high equity and have gotten two calls so far. It'd be great to hear what you would do next: 

The first guy wanted full market value of the property which is close to 750k for a 2BD/2BA right next to the Pentagon), there's no mortgage on the property and he's in no rush to sell. The second guy wanted over 100k over market value for a 3BD/2.5BA in Fairfax that was rented for $100/month below market and while there is a small mortgage on the property, he's also in no rush to sell. 

I don't see why I should be offering premiums to these people for their homes. I'm thinking of walking as opposed to lowballing them. What would you do? 

Also, any thoughts on how to improve my lists so that the buyers are more motivated?
