If you are near a military base there are many opportunities for selling homes and picking up buyers.
Active duty military not only a base pay, but a housing allowance. In expensive places such as Hawaii they also receive a cost of living allowance.
VA Loans have been an extremely effective tool in my business. Most of my buyers have been either active duty military or retirees.
One great resource for posting your listings if your are near a base is the DOD referral website: http://www.dodreferral.com/index_mil.php I post all listings in the area there. It is free and the response rate has been tremendous.
