>No one would actually pay 30% interest instead of 4% for a house, and there's no way the contract would hold up in court
Who will reimburse me the legal fees?
Lots and lots of people improperly lost their homes due to illegal robo-signing. They could have saved their houses if they had the resources to fight it in court.
There are several reasons the contract would be unenforceable. The main reason is that typos and obvious mistakes in a contract just result in the corrected contract applying.
Even if it were totally clear that both parties really intended 30% interest, which would not be the case, most US states have usury laws, 30% is way above the maximum allowed by any state. So the contract is automatically void in most states.
Even in states without usury laws, a mortgage at several times the prevailing rate would certainly be considered "unconscionable", making the contract unenforceable.
