I guess my questions is more around the efficiency of each method, which I guess can also depend on how you attack it.

But dog urine isn't usually that bad, and your first line of attack, painting the subfloor with Kilz, will usually be quite enough.In flips, the stench of pet urine is the smell of money.

It looks like what is called "Sulphur attack," and the concrete is simply crumpling away to nothing. 

Sorry if you get upset when people disagree, but if you truly believe that, you should be a heavy seller and out of the market the past 18 months.Like most people quoting articles, I think you suffer from a subjective bias, ie you quote people that agree with you and attack those that don't.  

@Marcus Johnson didn't you hear, Walz went on record a while ago saying COVID dosn't impact rioters (sorry, gathering WITHOUT permits, blocking roadways, smashing windows, burning buildings, hurling rocks and so on is NOT protests any more than chain-gangs are an "encouraged communal community improvement force" (see, I can word play too))BUT, apparently COVID hates Harleys because it "DOES" attack everyone at Sturgis......Seriously, why isn't there any news on how prejudice COVID is, it's selectively targeting people based on their political affiliations and hobbies apparently. 

It sounds like you have knowledge... what you need is a PLAN of attack. 

FYI, we all have access to Google & shortsalesuperstars.comThis barely deserves a response since the first thing you decided to do was attack me because of my profession.

I've seen several note holders make late, sometimes very late payments, the have a heart attack, or they die, or someting happens where they can't act, the borrower will suffer. :)

I wanted to be sure that Jimmy H. knew I wasn't attacking or judging him for asking about or trying this strategy.

College is mostly a waste of time now, imo (here come the attacks!)
