Vacant house, windows open, animals inside

[Marc Izquierdo]

Hi everyone I am looking at a duplex foreclosure. I was talking with a neighbor and he was saying that the property has been vacant for around 6 years. He noticed that from time to time, the windows would be open also. Eventually, the police would come by and close them. Today, while looking at the exterior, the windows were open. There is a birds nest on the outside of one of the closed windows (between the glass and the screen) and we saw a squirrel run into the house from one of the open windows. Besides potential and likely water damage, I'm assuming there are animals living in the house. The property is cheap and in a good area. I am trying to set up a time to walk through it with a realtor. I want to see if anyone else has dealt with a property like this before. How did you handle the animals in the house during the walk through? How did you prepare? Any insight would be great! Thanks in advance
