HOA for a new community

[John Jenkins]

Hi, 

So I'm in the process of buying a home that will be my primary residence but during the week when I'm gone, I'd like to rent it out as a short term rental. It's a new community and they're marketing as "perfect for investors" and "no rental restrictions". The listing agent said the builder is the one that has set the rules but the HOA has yet to become fully established. I know there are a few other properties in the community that are being rented out. My worry is that once the HOA becomes fully established, they'll all of a sudden change the rules to ban short term rentals. One of my friends told me that this needs to be voted on by the community and if anyone opposes, they won't be able to enact the ban. Is this true?
