So it is just tied to the tenant and lease they are signed into not necessarily anything where the property itself is declared as section 8 housing  and has to be rented as such.  

LA county is now restrictive unless it's a single family home and declared your primary residence or you build a ADU behind a SFR and claim that as your primary.

Typical language within those docs is along the lines of "all owners agree to abide by the By-laws, Declaration, and current House Rules".

Grit your teeth and muscle through this.

Per @Dave Foster I believe you have 45 days to declare your list, and 6 months to buy. 

I auto respond with a link to a Google docs form to fill out, having them self declare on the requirements that I place in the ad.

@Joseph Rixe, if you are referring to the Declaration/Covenants/Restrictions of the HOA or Condo community this is very common and I would not suggest purchasing this property to use as an Airbnb.  

The correct approach is to file an extension and file the return when you have all the information.This is what you signed on your return"Under penalties of perjury, I declare that I have examined this return and accompanying schedules and statements, and to the best of my knowledge and belief, they are true, correct, and complete.

My first officially active investor year I'm declaring to buy a fixer property to do the BRRRR method, house hacking a triplex!

You cannot buy another primary now if you go this route and declare it as a primary residence to get the best pricing.
