Trish,
You need to treat this asset just like any A-B site. Same marketing efforts if not more. The first thing is making your current residents happy, because I'm sure if they havent had a manager for over 6 months, the customer service has taken a hit at this site. You dont want residents unhappy, because they can influance future and current residents in this community. So, first I would do a resident meeting to introduce my self, and get as much items address as possible. Then I would schedule a resident appreciation party, which can be part of your renewal marketing plan. Once I feel comfortable that I have shown my current resident that there is a new manager and cares about them, then I would go full blast with open houses and outreach marketing for new rentals. I would even include a meet our current residents party. Hope this helps!
