I'm not sure if the house pictured is the same house that Sorrell owned in Sherman Oaks. Google maps has it blurred out and it looks like its a gated property. The listing says 5 bed, 5.5 bathroom, 3800 square feet, and is worth 3.8 million today.
As a Die-Hard Dukes fan who lives in Los Angeles, I never would have thought of looking for Sorrell's home! I simply read that he lived in Sherman Oaks. I definitely think that a successful TV actor in the early 1980's could afford to buy a very desirable house here in Los Angeles for a six-figure sum. Today that same house would have a multi-million-dollar price tag on it today.
One of the challenges for homebuyers in the early 1980's was that interest rates were at all time historic highs (18-21%), but a successful actor could afford to buy a house outright without a mortgage, giving them an advantage over other homebuyers. Surely, Boss Hogg wouldn't take on a mortgage with such a high interest rate. LOL
