Most of our maintenance is done quarterly, or every time that we are in residence.

However, annual maintenance is:

Heat and Air Conditioning servicing

Fireplace and chimney cleaning

Well pumps and filters checked

Pump out septic tanks and rotor rooter lines

New gravel on driveways

Check roofs, eaves, gutters, downspouts

Replant and mulch all flower beds

Power wash decks

etc.

And that's just for starters.....

Annually, our home gets a "deep cleaning" that is a 3-day process of going through every item in the home and cleaning it thoroughly.

In terms of maintenance, that's ongoing and we visit 3-4 times a year to replace and update "comfort" items in the home.  Monthly, we have ongoing maintenance and cleaning.

Erinn, I found the lists on here so very helpful, I have printed them and even put copies out for my cleaners to see. That was one of the first things I found so very valuable on this site back when I started.

Throughout the year we have whatever repairs or maintenance that is needed done by others and of course the housekeeper is cleaning regularly. We have found visiting 3 times a year to deep clean and do updates and repairs keeps our properties in better condition.

We're only about six months in, but here's what we're doing this spring:

Touch up paint

Launder curtains

Clean septic filter

Wash exterior of windows

Annual is not enough, we do quarterly:

pool chemical analysis etc

linen and towel check and replace

check door hinges and locks of closets and drawers to see if broken

pool deck boards - replace or screw down, reseal

paint front steps

paint interior to cover marks (almost weekly)

analyse water bills to see if there are leaks in the garden

remove large fronds from palm trees

check for termites in bushes within 200 yards

New beach chairs and umbrellas

External check for repairs

Replace smoke alarm batteries

Aircon servicing

Cistern water level (more like weekly)

Make sure gardener has trimmed bushes, hedges

Remove lots of garden waste, fronts etc

Restock to maximum the cleaning materials, toilet paper (this is constant but will do a max check if busy weeks ahead)

Ad hoc stuff which takes 3 times as long as expected
