Living in a house where there was a homicide?

So i have to move out of my apartment along with my mother and we only have about 50 days. (New owners and they want the house cleared) we found an AWESOME apartment big and we can make it beautiful and homey. But when i first got there and actually saw the outside of the apartment, i realized it was the house where a beloved person was stabbed to death and left in there for 3 days. I went to his funeral and his wake and the whole town was devastated about his death. Next month will make a year of his death. His mom lived in that apartment for 20 years but moved due to the fact she couldnt handle the pain of her son passing in there any longer. My mom really likes the apartment and im not going to lie, i love it too. She wants to get it blessed and i just want to move on and not think about it any longer. Can i ever get this out of my head?!!!!
