Each party complains about the other more than provides actual substance. :-)

I'd keep a reasonable reason for you to visit the property, say by Feb 1 to change the furnace filter and make sure you don't have a grow house or something along those lines;)  I see you are in CA, make sure you are covered in your lease for grows, illegal substance, etc.

@Lester Carbonell Try reading some of Don Campbels books they are good for beginners with lots of real substance, some people also Like Kyosaki but I find his books lack real strategy or substance.

@Jimmy Warr  careful on BP of one off lenders with no real substance behind them.. lots of scammers.

Generally illegal activity within the unit is grounds for eviction... all my units are also non-smoking so if they are smoking an illegal substance, they're violating twice over.Frankly, I'd get them out... the longer they stay, the worse that smell is going to get and the more it's going to penetrate every pore of the residence.  

In about 30% of cases, I've found that the spores present aren't even mold but if it's been leaking for a while onto any organic substance, odds are you have it.  

I'm a huge fan of this, and other forms of, "cash like substances".However, in this case, I would suggest you just refinance.  

That's the entire annual budget for EPA's "Toxic Substances: Lead Risk Reduction Program"EPA FY 2014 Budget in Brief page 96.

When in doubt and on the site just click somewhere and you’re bound to learn something of substance.

I maintain that your lease option strategy meets the form and substance of a dealer transaction, and thus, the property is not eligible to participate in a 1031 exchange.
