Not sure if you have neighbors nearby, but we have asked neighbors to collect our mail during long trips. I've also had younger adult relatives and friends to house sit for me. It gives me peace of mind that my house doesn't look abandoned for weeks on end. They usually live in apartments and bachelor pads and consider crashing at my pad a vacation. I will also send a gift or give them money after I get back just as a thank you. If you have neighbors, or friends/relatives that you trust, it's a move that will give you some comfort knowing that your home is being looked after.
