There are treatments available that will kill the roots, but, as you noted, damage is already done.

A professional mold treatment company will know the drill and be able to advice you on what needs to be done.John Corey

We did a new kitchen (granite, cabinets, appliances), all new bath fixtures and tile, solid hardwood floors, new carpet, new vinyl windows, brand new heat pump, water heater and 90% new plumbing, new lights, fans, and hardware, interior/exterior paint, built 12x12 deck, landscaping, repaired extensive wood rot and termite damage, termite treatment and bond, graded and seeded yard, reinsulated and lined crawl space.

State law may apply to water supplies and sewage treatment with a subdivision.

Also, to expand on Steve's comments, real estate acquired with the intent to fix-up and then sell (flipping) does not qualify for 1031 Exchange treatment.

Did you ever post any more posts regarding the spousal $60k threshold  or converting LLC to S-corp treatment and why?

You never have "investor" tax treatment for this strategy, never use long term capital gains tax treatment, your flip property can never participate in a 1031 exchange, and you can never depreciate the flip property.

Also, I do believe the Bora care w/ mold treatment is a good product.

A Borrower is entitle to proper treatment and accounting of their impounds and any surplus upon review.  

I think I could elect to have it treated as a corporation for tax purposes and that might avoid the treatment as a disregarded entity, but I'm told that putting real estate in a corporation is a bad idea.
