I know plenty of owners (of multiple properties) who regularly do the 'sunday drive-by' ie check out the exterior appearance, dwell (in their cars) for a couple of minutes then move on.
Going into the common property is a bit over the top and totally unnecessary - yes it may even breach the tenant's quiet enjoyment (esp if it is self managed).
We self manage.
We visit our properties more often than we want to because we make the repairs, and clean up after vacating tenants, mow the lawns at some places etc.
Since we own 2- 11 unit apt buildings, we are in the common areas a lot.
Tough luck if our tenants don't like seeing us.
Actually they don't seem to mind, unless they are the ones we are always chasing for money...then they can't scurry into their apts fast enough
