Now the market is fully valued expect some toxic sectors Let’s see if the market retests some lows, I am long so I ride it out.I am still of the mindset of S.F.H is the money maker in my area.

Tax sales are a way for a SELLER to get rid of a property that they can't sell otherwise; like toxic waste sites, mold problem, hazardous material problem, environmental problem, failed septic, failed well, encroachment, title flaw/defect, IRS problem.

I found out because I was proactive and looked up my taxes online.I don't mind paying my taxes, but when the representation I receive ranks in the gutter, that irritates me. 

There are mold testing companies in your area that can test if they are acceptable levels or dangerous/toxic levels.

But, after I respectfully brought my problem to the city manager, with photos, he got on it and changes were made fairly quickly, and a very irritated building inspector was back fixing things he should have been taking care of LOL.At any rate, that's what I'd do if I was you.  

Like a self-fulfilling prophesy  The fact that it gave you a hinky feeling goes to show that it's not something you'd be comfortable with, so that's a good indicator that your tenants wouldn't love it either.You just can't treat people badly, and then expect them to be a long-term ATM machine that spits out rent every month forever.But, of course, your PM probably makes money every time the place turns over, so they don't care if they are irritating the tenants and having to get a new tenant every year, because none of the tenants want to stay after their lease is up.

Even if you did have mold, it usually doesn't create health problems although it may irritate an existing health problem.

My biggest obstacle is my wife,  she gets irritated when she sees me researching anything that would be considered entrepreneurial.  

This irritates me too, but I had to let it go.You can put language in your rental agreements about guest frequency and behavior.  

Just like when you receive an increase year after year with your insurance, lawn care, phone bill, etc and they tell you it's "just business"... do you say ok and continue to pay it, or do you shop around and switch because you're irritated at them for constantly raising their rates?
