@Mike Williams , I'm not a lawyer so this isn't legal advice, but it would seem that you're bordering on blatantly discriminating against people with disabilities by excluding them out of hand.

Not a lawyer, so no legal advice, but if he is not breaking any city rules or regulations by having the RV there so long, then I believe this is just a blatant sign of a major marital issue between you and your wife.  

Maybe the best advice could be, don’t take advice from people who have 1 post on BP and blatantly tell you to violate Fair housing laws.  

As both a short and long term rental owner I’ll just add a few words of caution here...AirBnB and other vacation rental sites like HomeAway are great for the purpose they originated: short term rentals, but they offer minimal protection for the concerns of many owners needing to secure their properties for longer lease terms.As a traditional property manager I’m far more interested in ensuring I pull a full criminal background check, speak with a potential tenant’s present and prior landlord, confirm consistent employment/income sources for > 6 months, and ensure a potential tenant has a track record of paying other bills they have agreed to in writing like credit cards, car loans, and others.On the contrary, at best AirBnB/HomeAway/others give me the following info on guest/tenant: a blurry selfie (that could be their dog)confirmation of a non-specific government IDconfirmation of an email address I can’t seecurrent city/state of residencelist of reviews by individuals running a different AirBnB (that I have no way of confirming is not the guest’s best friend)Property insurance secured by (and in the interest of) someone who is not meWhile I’m OK with taking a gamble on unknown guests using my property for short term stays, stays of longer than 1 month generally involve: Someone looking to move significant belongings in with them (that I cannot legally remove in most states)Moving in for a period of time they’re generally unable to pay for entirely upfrontTenants receiving access only after a legally-executed lease, criminal, background, credit, and income check that’s par for the course in a professional, term stay arrangementEven beyond the blatant lack of risk mitigation tactics common in long term lease agreements, the fact remains that many STR platforms are also skimming 10-20% of gross revenue off the top of owners’ profits for little beyond the initial SEO and payment processing.

You're not going to be fined unless the discrimination is something really blatant - like screaming at a minority that you'd never take "their kind."  

All landlords need to learn this.It is extremely rare that a landlord will be challenged, unless the discrimination is blatant and then only when a individual files a complaint which is also very rare. 

Do not ask blatant discriminatory questions but get what ever info you need what ever way you have to.

I suppose I worded that wrong I would never blatantly lie, I should have worded it as ‘am I legally obligated to give full disclosure of this tenant’s habits and behaviors’

They'd have to prove that the reason you denied them was for a protected reason, and unless you have a history that can be proven of rejecting a certain type of applicant, or you blatantly told them you don't rent to "their kind" and they recorded it on their phone, it would be hard to prove.So, as long as the reason for denying them is never because they have a kid or too many kids or the color of their skin isn't like yours or they have a service dog or whatever, but the reason is because they didn't fill out their application completely or they were rude or smelled of cigarette smoke and you don't allow it, or they didn't show up on time or give you documents when they said they would - you're fine.

Having done that and asked for clarification on lease clauses 3 weeks ago, I still do not have answers.With a blatant breach of contract and what are clearly deceptive practices, I would like CSC to terminate the remaining two contracts on these grounds.
