My take-aways on 2 other points:1) Lease Option tenant buyer (TB):  Curious if you are familiar with Dodd-Frank legislation on these types of transactions. 

Do you have the legal skills to enforce the judgement? 

There is also a mandatory grace period.My guess is that the person had a problem enforcing the discount also didn't file an "insufficient rent" notice to the first person, he or she told everyone else & the rest just took advantage. 

Especially something that isn’t illegal.This will come down to: are you willing to lose out on multiple months of lost rent, turnover, legal fees to enforce the no smoking clause in your lease?

@Marco Padilla you have to enforce your lease.

2) I saw on one of the forums a post that there is something you can put in your rental agreement, which basically states something like: if one of the clauses in the contract can't be enforced, that it will not nullify the contract. 

As far as I understand, as long as the unit is not troubling the neighbors or causing issues, code enforcement will not be an issue.

Government - The State of Illinois is fighting over a series of legislation aimed at commercial property owners that have profited from everything above.

@Bill Brandt is correct that the legislation is not LL friendly but due to low vacancy it is not much of an issue if you screen well. 

If there were two kitchens, one of them would have to be removed, or reduced to a wetbar.The issue in Hawaii is enforcement and housing shortage.
