One thing to consider is your future tenant has to abide with those HOA by-laws.

There is an old saying in law that "A servant cannot serve two masters".

In reality, this is a process that requires (by law) that you enlist the aid of a Qualified Intermediary (there are a couple great ones here on BP).

(Assuming you are refering to the CA law) I don't think it is that big of a deal. 

The city I'm in is pretty strict on rentals and one thing the house did not pass on was the headroom at the top of the stairs going to the upstairs.

@Dan RomaThis article from a Dallas lawyer has a more reassuring answer, while this one from another law firm takes a more conservative position.

I think that is what happens, but I can't find any law on this.

you know what I would do I could careless what the law said..

Increasing rent is a very basic facet of this business and if you do not know this, I assume you do not know the rest of your local landlord/tenant laws. you should not proceed in this business until you fully understand your local laws, and how to operate within them. now to answer your question, any motnh to month lease, oral or written, usually requires 30 days notice and one full monthly rental cycle to change or end the contract. that means if you want to raise rent on May 1, notice needs to be given by March 31.

Check your Landlord/Tenant Laws before you even buy a home!
