Like Cappy, I owned a home in Pirates Beach. We used Sand N Sea as our rental manager.
Our home was just a two-bedroom, but it had a good view of the water (and great deck) and was only a short walk to the beach.
Unfortunately, two bedrooms are tough to rent, and rental rates in Galveston have fallen hard in recent years due to so much new construction and competition from VRBO, AirBNB and new management companies. Our revenue dropped about 25 percent from 2014 to 2017, despite more rental nights. We finally decided to throw in the towel and sell earlier this year.
Bottom line: Our rental income never covered our total expenses (because the house was too small to command top dollar rates). Our goal was to cover taxes and insurance, which we were able to do some years, Our insurance averaged about $8,000 a year (flood, wind, homeowners and liability) and our taxes were around $5,500.
I recommend Sand N Sea but you need to know going in that there are lots of little things these management companies do that are irritating. Their customer is the renter, and they will nickle-and-dime you for every little thing. I know people who use Gary Greene and we've shared plenty of similar war stories.
Plus, damage and wear and tear were much worse than I ever anticipated. I used to cringe every time we opened the door. LOL. And it's tough to work around the rental schedule; if it rents, you can't use the house, and if it doesn't rent, you aren't making money.
Happy to share more info if you like.
