Seeking advice on a condemned property in a GOOD neighborhood

[Justin Escajeda]

Hello everyone, I have recently become able to buy a vacant home in a nice neighborhood in Pittsburgh. Comps have sold for 130k-160k in the last 6 months. However, the house is now condemned. I am a contractor and can estimate cost pretty efficiently. However, because the house has been sitting vacant for 3 years, I wonder how much I should offer, aside from repair costs, how should I gauge my offer?

Also, being a landlord and property owner for a few years now, I have had my fair share of experience with cat urine. HOWEVER, THIS IS THE WORST CASE I HAVE EVER ENCOUNTERED. You can literally smell it from the outside. Before I have only repainted and replaced carpet to eliminate the smell.

Is there other measures that I should take for this extreme case to rid the smell, that I should include in my repair budget? Or is there techniques that I am unfamiliar with to complete this task?

Thank You everyone for your feedback, I value any that I get from this community.
