One of the first things a family with a special needs member must do when changing duty stations is contact the Base/Post housing office at their new duty station. Availability of housing is the biggest concern when making a station change. Not all Bases or Posts have single level accessible housing available for those who cannot negotiate stairs. If there is accessible housing on Base there is generally a long waiting list. It is imperative to get on that list as soon as possible!
If the waiting list for accessible housing is substantial, be sure to discuss what other options are available in that area with the Base Housing Contract Manager. Many duty stations are providing contracted, off post, housing with appropriate housing allowances. They should be able to assist you in locating local accessible housing within mandated travel range to your duty station. For civilian housing options go to the "Housing" section of this web site. One of these options may work better for you. You may also qualify for loans under VA, HUD, and FHA programs. Be sure to check those programs out.
Don't forget. You will qualify for full BHA if you are forced by lack of available military housing to live in the Civilian community. Be sure to check with the MPO at your duty station for all regulations and to ensure these benefits are paid out to you. It will be important to also check your monthly LES to ensure that benefit is being paid.
