Thank you Sam -- I think you make some valid points.

Is the house plumbed for natural gas?

I think an ozone generator will work well, too, but if the odor causing residue continues to off-gas it can come back.

The best solution would be to convert it to gas, if possible.

The history:Both (2 family) properties were originally built with chimneys venting two gas water heaters and two furnaces.

Is there a "nuclear" option like those Ozone machines, or some nerve gas level material I can bomb the place with!!

See: http://www.law.siu.edu/selfhelp/info/property/Land...I also found this, regarding a tenant's right to withhold rent for repairs, and your tenant doesn't appear to have done what what necessary to make her claim valid.

He started it way too late in life, for valid reasons that i won't bore you with.Several years ago, when the stock market was doing well, I might add, the folks who manage his 401K had a "check-up" meeting with hubby.

Say goodbye to tracking individual receipts - every single SKU that you buy goes online... this is true for both HD and Lowes.It's also super helpful to be able to hand your key players a charge card and stop having to do endless phone sales (Which take FOREVER if there's a line)IMO, it's a lot more helpful than having a business CC with employee cards... wrangling receipts is never, ever fun or easy when you're dealing with a process that may entail several trips a day to various stores.I also encourage the use of gas account cards for underlings for the same reason - they report every dime spent to your online account.

If I have four or five jobs going at once, am keeping my guys paid, gas in trucks, expenses paid, supplier accounts paid, and fronting labor and incidental material costs on multiple jobs, while feeding my family and doing some of my own investing, I should also have the cash to front him HIS cabinets and countertops?
