I hold accountable the actions of a landlord since the imbalance exists, in my state, that the legislation all but preempts informal disputes with plain language that must be contained in all FL leases (the right to action for actual damages).

@Eric Robert Here someone looking after <=  4 (or maybe its 6) kids (including their own) under the age of 12 in their home does not require a daycare licence and is permitted by zoning in all residential zones.You likely have similar zoning and family services legislation in your jurisdiction which will define what she is legally allowed to do and what type of insurance she must carry (if any).  

Not being as bright as many I make up with it by volume having done hundreds of these prior to the equity stripping laws and pre foreclosure laws changing in 08.. and I was doing wraps in mid 80S before most folks were even thinking about RE... had a company called California Wrap in the day.. probably did 500 or more of those.. in that scenario we only wrapped seller carry so there was never a risk of credit destruction for a seller.

If for whatever reason, legislation changes and plan documents need to be revised to stay current or be re-approved, that may come at an added cost if you've purchased a package for a set price.

They're welcome to go buy a place and make up their own rules...

Your screening process must not violate human rights legislation (Fair Housing Act I believe in your jurisdiction) and should be relatively transparent (read: defensible).  

Sometimes this can be done by legislation as Paul mentioned.

That was originally my plan, however legislation in Florida is creating hard times for realtors.

I can make up to $500 an hour using the Leverage afforded with trading the Futures and even more with the Options on the SPY.

Folks can certainly make up their own minds if they are getting a quality education or some spin of strategies that may or may not be replicated in their niche or in real estate in general.
