Hello loveit,
It's good that you have learnt from your mistakes. We all commit mistakes but the best thing is to learn from them and act accordingly.
You can possibly refinance both the loans into a single loan. But for that you need to shop around a bit with a number of lenders. Loan shopping will help you find out what lenders are willing to offer you – the loan amount (that’s important here as it's an 80-20 loan), the mortgage rate and the closing costs. Then compare the monthly payments and the costs and check out which lender requires you to pay the least. Also, enquire about his service background.
Your scores may not be that good but they aren’t too bad either. You will possibly be considered as a prime borrower considering your Equifax and Experian scores. This however, will depend upon the lender with whom you are dealing.
One more thing, if at all you don't get a suitable loan offer (though I don't think that's going to happen), only then it makes sense to sell the home and live in a cheaper place.
All the best
