In exchange of two rifles, masks, suits and various other equipment, Grimmauld Place became a literal shell of its former self. All rooms were emptied and the things inside sold out to gather enough money to fund their project. All that was left was one bed (which they had been sharing even before they became a couple), a love seat in the parlour, their wardrobes and clothes, and the kitchen table and chairs. Everything else was gone. Even the kitchen appliances were gone. It wasn’t like they had money to pay for food anyway – the only reason they weren’t starving was because Professor McGonagall gave them a favour, asking a few of the Hogwarts elves to bring them food every meal.
