You inflated the price $70k but they are only making $50k in payments.

I have on multiple occasions, once with one of my own properties and a few times for clients been able to not only get the money they paid for a property but also gave them extra money in a total loss (protected the equity that has accrued due to inflation in the industry).  

For example, if the inflation rate is 5%, what costs $100 today will cost $155 in 10 years.

But with the interest rate falling and the inflation stabilizing, they might be turning around the corner.

This is all indications of a super sensitive earnings, extremely sticky projected inflation, and the bond market being way in front of the Fed. 

I don't think it would make any headlines even if all those loans were called tomorrow, and with foreclosure rates being as low as they are, the banks could probably resell those properties quickly at higher interest rates, pocket new closing costs, get low interest loans making less than inflation off the books, etc.

You can save but it'll take years and it's nearly impossible to get ahead of inflation by saving, so you get creative and rental arbitrage is just that.

Which will inflate market prices int he segment seemingly over-night.

There are a ton of areas where the value could be significantly inflated on paper if you don't boots on the ground familiarity.

It's probably something that rides on top of the inflation but not very likely to double or triple your initial investment opportunities for sure.
