The house isn’t hard. We turn the water heater to “vacation”, turn the ac up pretty high in summer and off when it’s cool. I put a temporary halt on cable/net/phone; it saves me about $150.00/mo. My mail slot is in the garage and I have a big container, so mail isn’t an issue. At my prior house I had a mailbox so I had to depend on my son or neighbors to collect the mail. The DW’s sister took the indoor plants and my irrigation took care of the outside. I checked the house and eliminated anything I thought could be a fire hazard. The sheriff checked my house about once a week and the neighbors watched it all the time. About once a month my son would come by and check the interior and cut the grass if needed.
Bills were the biggest headache. I keep my finances on Quicken and after a couple of train wrecks I just went through it and found all the bills I pay in the time frame I’m gone. I don’t like automatic payment, so I use my laptop to access the sites and pay them online while I’m gone.
