It takes a little time to discover what one can reasonably expect from a rental/management company and what is out of their realm or what their weak points are. Ours is excellent on the rentals and working with guests, not as good on management matters, but improving. Storm prep is completely beyond their ability to accomplish effectively. However, things are really wild at the beaches when a storm is coming in. One reason that Walton County's emergency evacuations work so well is that they issue very early warnings on the bridges and mandatory evacuations occur very early. So the only people who are down there are probably busy securing their own property.
Our problems seem to have been solved by the following.
(1) Hire a local able-bodied person to do storm prep and keep your expectations reasonable. This means the decision relative to plywood must be made earlier than you might prefer, then you just have to live with it (and be happy) that it wasn't needed. If you wait too late, give it up and hope for the best.
(2) Accept that the company has limited personnel and time to actually do management and handyman tasks at your home. Make an arrangement with the maintenance person to compensate them directly for doing things. Try to consolidate requests so that they can take care of more than one thing on one visit to the home, if there isn't an emergency.
(3) Establish a personal relationship and good communications with one person in rentals and one in management, and tell them how important their responsiveness is to you. More importantly, let their supervisor or the owner of the company know what a good job they are doing. Copy the employee on your letter or e-mail to their Supervisor. Otherwise, they might never know.
(4) Remember these people during the holidays or on a special day, like a big birthday, birth of a child or grandchild, etc. Everyone has their priorities and you want to be one of theirs.
(5) Remember how hard it is for these companies to hire and retain good people in that area. There are far more jobs than there are qualified people to fill them. Also, many of these good folks are commuting an hour more more each way. I cannot imagine navigating traffic congestion and road rage every day, only to arrive at a job consisting of complaints from people one doesn't know. They are under double stress, from both renters and owners.
