Going in at $180 is not unreasonable for a property that has been sitting for 1 year.

Based on the information you provided it sounds like the landlord was unreasonable.

(B) If the landlord makes an entry in violation of division (A)(8) of this section, makes a lawful entry in an unreasonable manner, or makes repeated demands for entry otherwise lawful that have the effect of harassing the tenant, the tenant may recover actual damages resulting from the entry or demands, obtain injunctive relief to prevent the recurrence of the conduct, and obtain a judgment for reasonable attorney's fees, or may terminate the rental agreement.

I would think those are all important details to iron out first, and it's not unreasonable for us to ask to be kept in the loop of the process.

A difference in opinion does not make me "unreasonable".Your "mistake" is that you are looking onto others to see if it is a good deal for you.Much like..  

@Carlos EnriquezYou have unreasonable expectations both to imagine that a seller knows everything about his home and that an inspector will catch every thing.  

Making a low or unreasonable  offer may turn the seller off and kill the deal.  

If this property needs to be taken down to the studs then even up to $50-60/ft isn't unreasonable. 

In that regards, I do not believe that $2k is unreasonable at all.

But i just moved out a couple of weeks ago and in the 4 years i lived there - there was never an unreasonable amount of spiders.
