You can tell you've done your homework! You're starting to realize what many of the those considering relocation haven't yet figured out.
Three of the biggest expenses when moving are material, labor and transportation costs.
The reason so many folks are attracted to the growing number of mobile/portable container options is because they think they can reduce their out pocket costs by using relatively cheap or donated packing containers and supplies
(material) combined with their own sweat equity and the good will of family, friends and neighbors to help load/unload
(labor) for the relatively cost of a case of beer and pizza or sandwiches.
The killer expense in this DIY budget model is the high transportation and container handling costs
(transportation). The overhead expense to provide and maintain the heavy duty lift delivery systems (trucks, flatbeds, forklifts, containers, etc) that are required to handle each container at the time of pickup, during transport and again at destination is all part of what drives the cost up.
The other is the inefficiency of the handling method. Say you decide on using a 8'H x 8'W x 16'L container. An inexperienced homeowner will pack their household items and load the 1024 cu ft unit at an average density of 5 lbs per cubic foot. In other words they'll load 5000 lbs into the 1000' box.
The problem is that, according to data collected by the
American Moving and Storage Association, the average size of the those moving interstate in 2007 was 7400 lbs. Thus the typical homeowner would probably need two containers.
Each of the 1000 cu ft containers weighs approximately 2000 lbs. That means that an inexperienced DIY homeowner is packing, on average, 5000 lbs into a 2000 lb box - resulting in the linehaul transportation expense for the general freight carrier being based on 7000 lbs of gross container weight.
But...if you can't get everything into just one container, the typical linehaul transportation cost could be based on a gross container weight of 11,400 lbs (7400 lbs Hhg + 4000 lbs container weight). The money that was saved on material and labor is spent on the container(s) used to transport the goods. In many instances, this could be as high at 35% of the total transportation expense. Empty container repositioning costs drives the COGS for these inefficient options even higher. That could buy a LOT of pizza and beer!
For those contemplating containerized moving, another factor to consider is whether or not a mobile/portable container can even be dropped at both the origin and/or destination. Many homeowner's associations and local or municipal ordinances restrict or prohibit the placement of unattended moving containers on private property or public access thoroughfares. Be sure to ask before you get too far into planning a DIY move.
Most reputable full service interstate household goods carriers, on the other hand, only charge for the weight of goods moved and the accessorial services either requested by the homeowner or
required by law to complete their relocation.
The only time it makes good economic sense to use a container options to move interstate is if you will require some type of storage at either origin or destination as part of your move.
Currently most mobile/portable container companies allow up to 30 days free storage on interstate moves. Most of the tariffs used by full service mover require separate charges for the first day of storage-in-transit (SIT), each successive day of SIT and then a warehouse handling charge.
