I’ll use an analogy - if you want to make a lot of money why don’t you just become a doctor or a lawyer?

If you really feel something this simple needs to be fleshed out so much, have the client hire a lawyer to write up these contract terms. 

@Ayyoub Reza   There are a number of places to get agreements but make sure you get one that is current and state specific (here, legal zoom, a lawyer, real estate association ) Read your HOA bylaws what does it require to be included.

Do you know that in some states title insurance companies pay referral fees to lawyers who refer them business and are not required to disclose it?

Someone has a good lawyer to recommend?

I haven't had any issues from tenants regarding it and our lawyer says that our state of MD is quiet on the subject which means that it is OK to do.

Tried to do this once and the bank charged me $250 to ask their lawyer about it and refused my request.

Conflicted on whether I should sit down with a lawyer to draft a lease, or if Zillow's basic lease is sufficient? 

I'd be happy to take a stab at any questions you have.In related experience, I was a real estate lawyer in Tokyo for 6 years (catering to foreign institutional buyers targeting A-class J properties) and I owned about 60 units in two multifamily buildings in/near Tokyo for 5 years. 

You would need the help of a decent lawyer to compel companies like AirBNB or VRBO to disclose statements.
