Estimates are just that...estimates.
The only arbiter of true value is what someone is willing to pay. The marketplace establishes true value, not banks, realtors, or owners.
I have sold boats “worth” $50,000 for 25. I have sold boats “worth” $1500 for 3500. It’s buyer/seller, no one else.
Charging someone with fraud over an estimate is ludicrous, and a blatant abuse of power.
Wait until the same rules start to apply to Thorobred sales & costly dogs/cats.
