Found a home but they don't let me turn on utilities till buy?

[Mirzet Mehovic]

I looked at over 30 homes to buy. Found a great one thats basically ready to be moved into with just a little work. 2 family home. It has been winterized so plumbing is off and they don't allow me to turn on electric nor gas either until purchase. Purchase is as is and inspector cant inspect electrical for example if it is off. Should I be wary? Never had this issue before when purchasing other properties to not let us test utilities.
