The real world problem in real estate titling today is the pervasive need for title insurance. In a typical real estate transaction, both the buyer and the seller will have an insurance policy to cover losses stemming from a sale based on an illegitimate title. In theory, because title registers are public (at least in the US) and run by a the local government, you could have higher trust in a title (and therefore lower title insurance premiums) if you could query the current holder from the appropriate government. That said, I'm not sure why blockchain makes more sense for this use case than, say, a read-only API at land-register.<city/county>.<state>.gov.
