I want you to have legal advice and be comfortable with this decision about your home.Now I will tell you, unless your attorney is an expert and lease with option, subject to existing financing, owner financing, and other legal remedies for your situation, he's probably have a say don't do it.Then I reach for my nolo.com article, and go over the different seller financing possibilities.And I walk them through all the situations, from lease purchase to subject to installment sale to wraparound mortgage."

Don't get sucked in by so-called "mold remediators."

The short answer on how to remediate your floodplain problem is that you would have to apply for a CLOMR or a LOMR.

Does anyone have any  thoughts or ideas how I can remedy this situation  No I don't have any friends and family to ask  for the extra 6000.

@Nathaniel WennerIf it’s $3k in mold remediation I would refund the $50 for the mold test.Why?

That's a silly move that you should remedy as soon as possible.Multiply the annual cash flow number you get by 20.

You did the remediation to reduce the chance of it happening again, but it isn't guaranteed.

Every state has their own rules regarding underground oil tanks and some will pay the cost to remove and remediate.

Demo all the drywall out, remediate mold, complete reshingle of roof, replace all windows, replace all outside soffit/fascia/dormers, replace all siding, repipe whole house, rewire whole house, redo all mechanicals such as hvac, redo all interior and exterior doors, paint interior and exterior, replace any framing or insulation damaged by mold/water leaks, replace all gutters, minor landscaping, minor outside repair of concrete wall, install all new cabinets, install all new countertops, replace everything in 6 kitchens, replace everything in 6 bathrooms, install handrails,  install significant flooring and minor subfloor repairs, and install all trim in house.Project will cost around 150,000$.What would be fair for this?

Third, if sewage is backing up into your basement, it requires professional remediation immediately.
