Single family homes/small multifamily (4 units or less) and the stock market are based on the most illogical substance on the planet: emotion.Best,

Substance over form, step transaction, etc.As far as i understand tax authorities don't know who conducts transactions with cryptocurrencies, to what extent and for what profit.Not to further lay it on you (two people have already said something), but no successful person I know thinks like this. 

While no mold assessment or testing was performed, a mold like substance was noted on the structuralcomponents of the basement and crawl space.

Do they have a substance over form argument - sure! 

You could claim all you wanted it is rental income, but the IRS is going to look at the substance.

I make them pee in a cup first, then I peel back a label to see if they are drug free for 9 substances of abuse. 

Originally we though we'd live in the condo 2 years and then the multifamily 2 years, but it'd be nice if the primary residence designation is easily changeable....if the multifamily does not close, then we would have the condo as our primary residence. not sure if that important of an issue...4) The contract that has disclosures about lead and radon...we live in New Jersey, so for renting we sign disclosures about lead, since all the houses here are old and anything prior to 70's will have lead, so in the contract when they have radon....lead....naturally occurring substances in New Jersey, is this standard in the contract? 

If it's important to you, I'd call it out and say: no smoking of any substance, which includes, but is not limited to tobacco and marijuana.

Can usually have them ordered out by the sheriff very very quickly. ....or if "controlled substance" is discovered on your property by you once you came to "check on heating zone valve".

To me, it sounds like you know a lot more about inner city restoration than you say.You identified many of the major stumbling blocks: "the rules", negative role models, substance abuse, not cooperating with the police, mass displacement all at once, etc.
