10 Things to Check Before Leaving Your Tenerife Home for Three Months

• Water supply — consider shutting off the main stopcock if nobody will be checking in, or at minimum know exactly where it is
• Electrical circuits — unplug non-essential appliances and check nothing is left running unnecessarily
• AC systems — set to an appropriate standby mode rather than fully off in humid periods, to help control moisture
• Fridge and freezer — clear anything perishable and decide whether to switch off or leave running
• Pool arrangement — confirm who is maintaining it and how often, in writing, not just a verbal agreement
• Garden and irrigation — adjust timers for the season rather than leaving a summer schedule running into cooler, wetter months
• Mail and post — arrange collection or redirection so post doesn't visibly pile up
• Alarm and security systems — test that they're working and that whoever holds emergency contact details is reachable
• A named key holder — someone who can actually get in if something goes wrong, not just someone with a spare key and no plan
• Insurance — check your policy doesn't have exclusions or conditions for extended unoccupied periods

The gap most owners miss

Most of this list is manageable to do yourself before you fly. The part that's harder to solve alone is what happens in month two, when something does go wrong and there's nobody local checking in. That's the specific gap Casa Plus's property checks and key holding are built around — someone actually walking through the property on a schedule, with a photo report, rather than hoping three months passes without incident.
