This is a tough problem that we encountered at TrueCar. People buy a car every 7 years, so a customer today will not be top of mind in 7 years. Before the pandemic we were working on a feature that would keep track of cars you own and suggest maintenance, parts, etc that would maintain resale value. For your home buying example, maybe there are services that you can offer related to home ownership (e.g. subscription based handyman or gardeners), so that you can be top of mind month after month, not just once a decade when people buy houses. You can then be a great resource when people go to buy a new house as well.
