All the light bulbs I can that are removable, bathroom and kitchen towels, any soap, router and cable modem, chargers and batteries and if using a bag vacuum, the bag out of vacuum as well as any filters and belt.
Now if I really wanted to be truly inconvenient for services, take outside cable splitter, or cable coupler and put lock out filter in place, now if I really want to make it hard take the RF cable tap on the main cable line on the pole. Now when it comes to washing clothes? Would just take the inner rubber seal to the door, so water leaks out and dryer the flexible ducting pipe to turn room effectively into a Sauna. Now heating and cooling for heating if winter, take the control module, or relay, or thermal fuses for furnace. If I wanted it to work for short time I take the pump and for summer AC take the main contactor on outside ac compressor, while leaving the thermostat in place and leaving no hint, so furnace still blow air out of vents, so you think it may still work, just no cool air. For ceiling fans take the motor run capacitor. For refrigerator take the defroster heating coil, you love when ICE built up every day. Now for toilet would be to obvious to take the whole toilet, I just take out the wax ring, or rubber seal that goes under the toilet, so when comes time to flush, you have a decent size mess to clean up. If I took whole toilet you replace the toilet right away, but if just the seal, you might drag on that and deal with the mess for a while, so be the most inconvenient. For shower would just take part of the pipe, or PVC that goes to the drain and screws to the knobs and if you have separate knobs for cold and hot would take the labels plate, for sink the bottom drain pipe. For garage would take one of the main springs to the door and also the main latching mechanism to the rail track for garage door opener, so you force to open manually and would be quite heavy as door will be missing a spring, then again may leave the spring as just want it inconvenient for someone, not to hurt someone? It could be any few combinations or all? Have to make it not noticeable right away and you have to dig deeper to find issue, or call someone, so you put up with it for a day, or more and is truly inconvenient,
I'm taking all of their fire starters, kindling, matches and lighters.
