well your description of the situation is not complete.. do you know its landlocked.. somehow if there is a home there I suspect it is not.. but it does happen I am in a landlocked case right now been two years fighting it thankfully I have title insurance and they are paying the lawyers.. first thing you do is not rely on your own due diligence if your not a surveyor or familiar with maps etc.you do one thing first .. you order a title report.. you may have to pay for it.. say 200 to 250.. your probably in a title abstract state. ( not sure but most of the NE is)  the title company hires an abstractor to do the court house work they will then write you a title commitment.. if your TRULY landlocked there will be an exception IE they wont insure access.. if this is missing then you ask them to clearly denote on the plat map where the legal access is.. you then take that map and see if it works on the ground.. 

Also why do many houses on a MLS only have one of the two in the description.

They are NEVER true service animals.Our property description always indicates no pets yet nearly all applicants have a pet and then state they are ESA or 'assistance'.  

Does anyone have a finish carpenter who is detail oriented and fits the above description?

Under that same description you will also find lenders that will approve you based on bank cash in flow, if you are self employed, rather than your net income on your tax returns. 

Based on my interpretation of the description, It appears that the property is divided by percent between the two entities.

They were flexible and willing to work with me even though my geographic location offered some significant challenges.

Slightly worried with the listing description saying "(Property is being sold in as-is condition, buyer is responsible for the use and occupancy permit)". 

In NJ and PA, I am very aggressive with my marketing (local letters, weekly open houses, free staging, professional photos, great descriptions.)

Based on the description you gave, it's a decent lawsuit waiting to happen.But with that said, I would personally sell it at a premium.
