So as to not talk past each other I'm specifically talking about present and future vanilla residential real estate transactions. For example w2 income with history, deed in your name, <10k sqft lot sfh or condo/townhome in a city.
For these things I struggle to imagine a future where the government does not have a clear view as to who owns and can transfer property (property taxes, IRS filings, Fannie/Freddie, recorded deeds, etc). They are backstopping the mortgage, they should understand what they are lending against.
I think overall, what a lot of this entire discussion misses is that 90, maybe 99% of transactions are pretty straightforward, but the 1% where things go haywire, might cost 10, even 100x as much in wasted time, money, etc. Real estate brokerage is a regulated professional service which means by law, there's a minimum standard of care owed to anyone who uses these peoples' services. This costs money to provide which ultimately means a lot of the costs of the problem cases end up socialized/spread out, over everyone.
This feels quite unfair if you've got your act together and everything goes smoothly, but it seems hard to know upfront which ones will be the hard cases, or not.
