Vacant property with moisture but have to wait 30 days

[Jeff Bridges]

I have a property under contract to close approximately jan 30. The pipes were stolen prior to contract resulting in water gushing inside and wet carpets etc. The humidity is high and carpets are not going to dry out. There is no power to run fans or dehumidifiers etc. Mold is starting to form on the carpets. i'm trying to close sooner but the concern is if I cant get in 30 days, mold will begin to grow. Any recommendations on how to stablize property without power until I can get in, turn on power and dry the place out and pull carpets etc... Bank seller is not amenable to spending anything on the property before I settle. But I can ask. What would you recommend? Thanks in advance!
