TS, I can't offer much help here but know that i completely understand the financial stress you are going through. I've been in a similar predicament before and it gave me many sleepless nights. Although my income to debt ratio was not overly unhealthy, but thoughts of 'what ifs' always give me an uneasy feeling.
For your case, the immediate short term solution I think is to rent one of your properties out, though it won't cover the full mortgage repayment, at least it covers the interest portion of it and the rest goes towards your principal like forced savings. Anything wrong, you can sell your property as a last resort. You are already in a better state compared to many families who are living paycheck to paycheck to support their family, but unlike you, they can't sell their commitments (children, wife) to recover their money.
