We have a few DHA lease properties and they are very much easy management. The lease is for whatever duration is stated in the original agreement and cannot be changed by the owner. If you want to sell there are certain stipulations. You cannot hold auctions or put up for sale signs, and it is often difficult to arrange inspections as you often have to go through a third party as well as the tenant. This makes them much more suitable as a long term investment. The rent they pay is also subject to market value and can go up or down. The up side is they always pay not matter if the property is vacant, and they cover all the maintainence in the management fee.
DHA have the right to change the length of the lease by one year, but other than that it is pretty well locked in.
