Why would it collapse?
Nobody is able to afford to buy/live in your property anymore.
If you don‘t find buyers/renters how will you manage to pay off your investment credit you took out at 95%credit rate while only covering contract signing fees at ~1% interest with 10year stable interest.
Once interest is adjusted after 10years to 4-5% you (property owner that can’t find any high paying renters) are fucked
