Welcome to the forum! We refer to these as project boats. Have you had it surveyed? Getting a professional opinion would be a good idea in this situation. Will also be important to check around the windows to see if they have leaked and there is rot in the cabin walls.

Welcome aboard. As Mr. OC noted. A survey should tell you the extent of the damage to the deck as well as other potential trouble spots (money pits). IF you haven't had a survey done put off the deal until you can have one done. IF the deck has soft spots, it is NOT "in good shape" as you state.
