Weldon Spring, Missouri
Sell your home and stay in Weldon Spring.
Weldon Spring is one of St. Charles County’s quieter corners — newer subdivisions tucked near the Katy Trail and the Busch Conservation Area, with plenty of green space and Francis Howell schools.
Mainstay buys Weldon Spring 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 Weldon Spring comps
Your estimate isn’t a number we made up. St. Charles County publishes actual sale prices, so your Weldon Spring estimate is built on genuine recent sales near you — real comps, not a county average. It’s a sale plus a lease — not a loan, mortgage, or refinance — and the price is set transparently, with no negotiation games.
