DH is Coast Guard. We are slated to transfer next June. Our last two transfers we've rented houses. We currently pay probably too much then we should for the house we have (we wanted a house with a fenced backyard for our dog) Our next move we most likely wont be staying the entire 3-4 years since DH will be moving up in rank while we are there, so we'll probably get moved again early.
I've been thinking about possibly renting a nice luxury apartment next time to take advantage of amenities for DD (pool, playground, etc). The only negative would be having to take the dog out to go to the bathroom frequently. I also think that renting a luxury apartment would be cheaper then a house (and it wouldn't be for a full 4 years most likely).
