For ex. You bought a house valued 1M with 800K loan. 80% LVR. You pay interest only. Unfortunately house value fall to 750K and seem like happy diving, but you can still pay the interest on time hopping the price will gain ground again one day. Will lender ask you to repay the loan to avoid further lose? Sound reasonable but also scary. I am not asking possible or not. Instead a question: have you experienced or not? Thanks!
