The "no money" aspect, strictly means that you are not purchasing the property yourself, you would be assigning the property to an end buyer.

(At least in Illinois, laws can vary by state)Sounds like they are trying to get you to sign a buyer agreement which is not a very common practice today, some agents still do this but not all. 

The complex has the right to be strict on this. 

I already live in a home with a detached mother-in-law that pays a good chunk of the mortgage.

I suspect many of these sub-leasers aren't paying attention to tax laws, zoning, or any other rules.

The big news here is that a class action law suit is going forward against the City of Bedford in the Northern District of Ohio contesting "all homeowners who were forced to endure government searches as a precondition to the sale of their homes are entitled to demand refunds of illegal “Point of Sale” inspection fees".A similar suit has already been adjudicated in the Southern District Courts in favor of prohibiting the practice as a sale requirement.41 communities in Northeast Ohio require some type of POS for title transfer which I'm sure is a source of income the cities don't want to see disappear.

Some states have common law marriage , after so many years and kids , they could consider you married .Safest thing ....................stay single and keep it zipped up 

If so most buyers (and their home inspectors/lenders/fathers/brother in law that's a contractor,etc) want to see circuit breakers.

Of course you have heard the phrase "ignorance of the law is no excuse" You can certainly put it in your lease but you cannot enforce it. 

@Nina Grayson CA laws may dictate something specific, but you need a contract between you and the "reverse wholesaler".
