A few years ago an apartment in my building was up for a foreclosure sale. Price looked good but turned out it was literally impossible to figure out (1) how much or the original dead beat's mortgage i would be on the hook for (2) tax burden and (3) unpaid coop fees i would owe.

So even as finance save person already in the building, it was impossible to figure out what I'd be getting/owing. Really ruined my taste for these things.

Years ago when I was thinking of moving, I started looking at houses with my real estate agent. I started asking about foreclosure sales and he said the same thing. Seller and seller's agent will try and obfuscate the numbers to make it look attractive and essentially "stick" the buyer with something that costs way more than its worth.

It's crazy how this isn't simple. Surely all they have to do is to tally up the debts secured by the apartment, then sell the apartment and use the money to pay as much of the debts as possible. Any remaining debt is the lender's loss, that's the risk they take when giving out loans.

If any debt does need to be tied to the apartment rather than the person, then it simply needs to be registered in a publicly (easily) accessible way. If someone fails to register their debt in a timely manner then it should be forfeit. It should be registered at the time it takes effect. Lender should be responsible for making sure the registration is complete before giving out the debt, if someone takes out a loan then sells it before the debt has been registered that's the lender's problem. They can't retroactively add a lien to my property because the previous owner took a loan when it was their property. That's not reasonable. If the lien is not registered then it doesn't exist, it should be that simple.
