@Louis Jara We had nearly the same thing here in PA, except it was two failed systems. It ran into a municipal wall and essentially required a full replacement of both. The only fix was an investor willing to take on a huge burden for a few months to tackle the project. Many lenders won't touch it, but private money or a JV where the lender gets ownership after the reno is worth exploring. I'd lock in a real septic bid before you finalize the capital stack. What's the as-is vs. repaired value looking like?
