Lake St. Louis, Missouri
Sell your home and stay in Lake St. Louis.
Lake St. Louis is a planned lake community built around two private lakes and a golf course — predominantly newer homes, with water and recreation at the center of the neighborhood.
Mainstay buys Lake St. Louis homes for 80–95% of their value, pays off your mortgage, and leases the home right back to you — so you unlock your equity without leaving your home, your schools, or your neighbors. We serve all of St. Charles County.

Your number, backed by Lake St. Louis comps
Your estimate isn’t a number we made up. Because St. Charles County publishes real sale prices, your Lake St. Louis number reflects what comparable homes — water-access premiums and all — actually traded for. It’s a sale plus a lease — not a loan, mortgage, or refinance — and the price is set transparently, with no negotiation games.
