Hi, I'm Brad Donley, founder of Einstein Real Estate Development. Our office is located at 520 Huber Park Court in Weldon Spring, just a short drive from South County via I-44, I-270, and I-255. We're not a faceless corporation — we're a family-owned business that genuinely cares about the people and communities of the St. Louis area.
When you need to sell your home quickly, the last thing you want is a complicated, stressful process. That's why we keep things simple, transparent, and fair. We treat every homeowner the way we'd want to be treated ourselves.
To help South County homeowners sell with confidence — fast, fair, and without the hassle — while revitalizing the communities we love.
South County — the southern portion of St. Louis County — is one of the most established and family-friendly parts of the St. Louis metro. It stretches from Affton and Lemay near the city line down through Mehlville, Oakville, Concord, and Green Park, and west toward Sappington, Crestwood, Sunset Hills, Fenton, and Lakeshire. Anchored by major corridors like Lindbergh Boulevard, Gravois Road, Telegraph Road, and I-55, it's a large area of long-time homeowners and tight-knit neighborhoods.
Much of South County's housing stock is classic 1950s through 1970s ranch, split-level, and two-story homes set on quiet, tree-lined streets. Many of these homes have been lovingly maintained, but a large share still have original kitchens, baths, and mechanicals that need updating to compete on today's market. If your South County home falls into that category, listing with an agent usually means months of repairs, showings, and uncertainty. A cash sale lets you skip all of that. We've bought homes throughout the area — from ranches in Affton, Oakville, and Mehlville to two-stories near Sappington, Crestwood, and Webster Groves.
South County is served by well-regarded school districts including Mehlville, Lindbergh, Affton, and Bayless, which keeps demand strong for move-in-ready homes but leaves dated properties sitting. If your house needs work you don't want to pay for, we can help you sell quickly and move forward without spending months and thousands of dollars on renovations.
No matter your situation, we can help you sell your South County home fast for cash. Here are the most common scenarios we see.

Absolutely not. We buy houses in South County completely as-is — whether it's a mid-century ranch that needs updating, has foundation issues, roof damage, or anything else. Don't spend a dollar on repairs, cleaning, or renovations. We handle everything after closing. This is especially helpful for the many 1950s through 1970s homes across Affton, Oakville, and Mehlville that still have their original kitchens and baths.
None. Zero. We cover all closing costs and there are no agent commissions. The cash offer you accept is exactly what you receive at closing. What you see is what you get — we believe in complete transparency with every homeowner we work with.
