Good Tips I found

Make sure that someone knows your travel plans, and can deal with emergencies (do they have a key?) in your absence. Suspend your mail delivery, or have it forwarded appropriately (to a rented P.O. box if a long trip makes it necessary). Cancel your newspaper delivery. Inform your credit card issuer(s) of your travel dates & locations, else they might suspend your account(s) when unexpected charges appear from far afield. Make arrangements for the care of any pets in your charge. Adjust your thermostat settings & check its batteries as appropriate. Clean your toilets, and anything else prone to "growing" stuff when you're not around. Check your refrigerator & other storage locations for food that could spoil. Turn off taps, on washing machines and anything else that could leak or freeze while unattended. Dispose of your garbage.

Schedule the payment of any bills that might come due during your trip; switching to on-line payment options can facilitate this. If using a cellular telephone with a prepaid plan, ensure that it has sufficient remaining time. Inspect all your doors and windows to ensure that they are secure; garage doors can be "locked" by inserting a large bolt through one of the tracks in which the door rides (there are usually holes for this; if not, drill one). If you use an alarm service, notify them of your plans, and let them know who to contact for emergencies. If you live in snow country, consider how a virgin snowfall (or drift) makes it obvious that your house is unoccupied. When appropriate, arrange with a neighbour to create car and foot tracks into the house. Or even shovel/plow. Unplug things (don't just turn them off); your gadgets will be safer and more rested, and why pay for electricity to keep remote controls functional while you're away? That said, leaving a couple of lights on when you're away gives your house an "occupied" look; use energy-saving bulbs, ideally on a timer. For an even more crafty/elaborate approach, consider using a fake TV. Water your plants. Get Travel Insurance
