Just a suggestion, when you look at the details page of any property (no login usually required) more information is available. In this properties case, it indicates Sale Pending below the photo. There are others.
In Michigan, real estate professionals can only represent your best interests (as a buyer) under a signed buyers agency agreement. I suggest finding out more about this before proceeding, you may be providing information to the seller that would cause you to pay more for a property.
Just to add to Liz's excellent comment about bringing a contractor.... Most real estate professionals are not experts in construction or certified home inspectors. We can relay our opinions about a homes condition, but you must do your own Due Diligence by hiring professionals in these fields to make the final decision. Most real estate contracts will include a clause stating this in better language.
