Advice need in Maryland for wholesale property!

[Leah Taylor]

Hi, I'm a new investor and believe I have a good potential. Listed at 120k, comps are solid at $250k. Problem is haven't seen the property, owner is still in property and it's been listed for 1 day. What are the risk if I offer full ask sight unseen?  It's a 1100sq ft home, imagining Reno can't be too excessive especially if owner occupied. I don't want to loose a good deal because I'm nervous I haven't seen yet. Any advise?  

Thanks!
