I have been involved in many properties like this. Look through all those open work orders and find your most urgent. Major water issues, pests (bed bugs, cockroaches) and essential appliances (refrigerator/stove) first. Call to confirm they are still issues and as you address those take care of ever thing else in that unit you can reasonably handle. 200 is going to turn into 400 once you start calling people. When it comes to curb appeal tackle the labor only items. Broken/damaged signs, safety hazards, trash, dead plants, over growth, etc. Invite residents to help with plants and trash if you have areas they can help. Pride in their community goes a long way on improving things. Then start tackling one household at a time. Take care of your non payers first, move to your problem children/hoarders, cleaning up the residents issues will make dramatic improvements in the overall care of your property. The good residents will appreciate it and you will attract new. It takes about 18-24 months to make dramatic improvements at distressed properties. Give yourselves the grace to know it is a process. I also invite residents to a small event like a coffee hour or popsicle at the pool to meet the new staff.
