I'm starting a home business in Lake Havasu City, AZ. Lake Havasu City
is a tourist community and home of the london bridge. Many people have
second or vacation homes here and are away for long periods of time.
I'm offering to watch their homes, go by and check on them for a fee.
"House Watch" is a perfect name but it's already taken. I'm looking
for an altenative name. I'm a full-time police officer and would
consider playing up that angle in a name if it worked.

Home Guard
Home Guard Security
Cottage Watch
Homestead Security

Home Force Security
Home Secure

Were you thinking about including "police" or "cop" or "officer" in the name?

I think "The Watchman" would be good a name for a house-watching
service that is offered by a police officer.
