What's it worth? A reasonable offer would be equal to or somewhat less than what it's worth.
I know that's not the answer you want. You'd like a solid number like: $52,000. But that's not possible. We know it's not worth $60,000, or it would have sold. But how much less? And part of the answer depends on its condition. You could have two properties, side-by-side, identical, but one could be worth $20,000 less because of damage to one and great condition and upgrades to the other.
Only a local agent who has actually seen the property (or will see it at your request) can give you a solid answer.
Hope that helps.
