> Most buyers get title insurance,

This is because all lenders require title insurance as a requirement for receiving the loan monies. So for almost all buyers they have no choice, their bank/credit union that is actually putting up most of the money forces it upon them.

Not all buyers are using loans. First house I sold was to someone who refused title insurance because in his words, "that house has been sold 3 times in 10 years, the title's fine."
