But you can avoid this treatment. 

I'm working on a parcel right now that has some old graves on it, is bordered on 3 sides by an old landfill, a sewage treatment plant, and a radioactive waste storage facility, and there are 2 homeless squatters who have been camping on it for 5 years. 2.)

I've also had Ozone treatments that probably work for minimal smells.

No previous treatment is visible and none is disclosed.Recommend professionally treating and repairing all damaged areas to restore structural support of affected framing members.No associated structural damages visible within home during time of inspection.Sellers answer: We can get it treated and at most will need to sister in a couple floor joist.MAIN WATER SUPPLY:Maintenance Item.Plumbing supply piping is made of galvanized steel.

Truthfully, It may take more than one treatment to rid the place of them.

Also following from what you wrote... so the tax treatment of the lender profit = interest is the same whether the lender pays interest monthly or only one time at the end of the project?

Maybe a clean type treatment.

Every good borough has its less desirable area (next to sewage treatment perhaps) and every bad area has its safer portions. 

Installment Sales Treatment (you pay the tax as you receive the money)4.

After years of lack of treatment (we were one of many caught in the Phoenix VA "scandal"), severe underpayment to him, zero support and lots of paperwork, we are in a MUCH better place.
