Abandoned stuff in house bought in Auction

[Gudia Kaur]

I am new to Real Estate Investment. Recently, bought a house in Auction that have everything still there, clothes, furniture, shoes, photos on wall and dressers, food in kitchen, vacuums, and all personal items. Its a huge mess and half of garage is piled up with boxes and lot of stuff. The grass is about 4 feet high and looked like a hay field.Utilities been out for last 1 yr so nobody is living there. I need advise on what step should I take next to move all this stuff out? Should I clean up myself and look for valuables first or Ask general contractor to dump out everything and fix the house? Any guidance is appreciated.
