Foundation under house on stilts
Yes, I have a suggestion. Spend some of the $$$ you're saving by doing the work yourself on hiring a Structural Contractor for advice. There are times where you spend some of that saved $$$ for sound advice. I think this is one of those times. Besides, how can anyone from here see what's going on? Our advice could end up sending your 1st floor into the basement. (As usual, our intentions are well placed ...)
My best to ya and hope this helps.
