Only real estate nowadays, not so much cars.
Friends of mine knocked on doors to buy their last two homes. The first home they knocked on the door and bought it for $120K in 1968. Sold it for $3,5000,000 in 2003. Property taxes of $25K+ a year made 'em move crosstown. They knocked on a door of home in 1995 and bought it for $375K. It's worth close to $1,000,000 today. Yes, it pays to knock on doors.
The difference today is that people doing it now usually don't have the money to buy what they say they want..lol..cracks me up!
A guy at the service station my Mom used to drive her low miles Blazer to for gas, told here to call when she wanted to sell. She did - he didn't have any money. A guy in CA. told me to call him when I wanted to sell my '83 300SD (that one clown who knows who he is claims I never owned.) I did, the doofus didn't even have a friggin' $2,500. Good Lord! The car turned for nearly $5K inside a couple weekends. A gal in Arkansas liked my new '80 Lincoln Town Car so much, she told me to call her when I wanted to sell it. I did 15 years later. She didn't have the $2,500 for it.
Anybody notice a pattern in the would-be buyers here? lol
