I asked for advice that was all. Asking should I hide money is asking advice! I don't have a financial brain hence I'm here seeking advice
You are effectively asking us how to defraud your bank. But you can afford to pay them back and have no extenuating circumstances. And you also have a solution to your predicament.
Sell the house, pay back the NE. That leaves you with 15K to maybe 25K. Go and rent somewhere cheap and save the money to build your next egg back up. And chose somewhere you only need one car. No headaches, no cheating the bank and keeping yourself honest. Far better than what you are trying to do.
