They will give you a warning notice to move out, then you only have a few days--I mean like 5 days tops. Then if you still don't move out they will file and eviction lawsuit and those go very fast I would go ahead and assume you have a week at the most to be on the safe side. By the time a sheriiff knocks on the door you could be arrested for trespassing.
You do not say in your post whether you are the former owner of the house or a tenant of the former owner. If you are the former owner, you can be moved out of the house by the sheriff as soon as the judge issues a writ of possession. In some counties the sheriff will give you 24 hours notice before physically removing all of your possessions from the house.
If you are a tenant, the HOA will have to give you notice to vacate the house and go through eviction proceedings. In either event, you should contact the HOA and try to negotiate a longer time for your to vacate the house. If you are unsure of your rights or would like help in negotiating with the HOA, you should consult an experienced real estate lawyer in your area.

You should attempt to negotiate renting the home since that is what the HOA will do with the property anyway. Unless you had a volatile relationship with your HOA they should not have any objections to entering into a valid lease with you provided you have income and are able to pay rent.
