Install our leak detectors at every water inlet, next to water heaters, by problem drains, in basements, by sump pumps.  They email and/or text you when there is water where it shouldn’t be.  You call the homeowner to let them know there is a problem, instead of waiting for them to notice damage and then do a web search to find someone to handle repairs.  You can turn off the main until you can fix it!  They get a substantial discount on their property insurance and you have an automatic calling card with a built in customer.

Re-sell the units or rent them monthly for a new income stream, since you will provide the monitoring service and emergency response.
