Help! Shocked to find water running all over new purchase

[Dylan Detert]

Recently we purchased a vacant property that was part of a package of properties.  The properties were purchased from a seller that was forced to sell the properties as part of a city crackdown on slumlords, and the city had assigned a property management company to manage the properties back in May.  We closed on December 28th, and after going round and around multiple times, I was finally able to get keys to the properties today, January 8th. The property management company said they could not give me keys because their lawyers could not confirm the closing, even though everything was completed on the 28th.

Today after receiving the keys I went to the properties and talked to the tenants in the ones where there were tenants, and when I got to the vacant one, I could hear water running inside.  When I opened the door I was astounded to find both the bathroom sink and kitchen sink running, with both drains clogged, and water pouring onto the floors in both areas and going through the floor into the basement.  In addition, there is now mold covering all of the walls and obviously huge repair costs.

What are my options? Do I go after the property management company?  I am still in shock and looking for any help that you can provide. Thanks!
