I have a DHA property and have spoken about my experience and accessing finance to secure proeprties for DHA at some of their seminars back in 07. So take my comments how you like.
Essentially we bought a DHA as IP#5, as we were sick of chasing tenants and agents for rent, we wanted hassle free. We did our research understanding that at the end of the lease we would have a property in an area that we would own and have to rent out ourselves. (I find many I speak to about buying DHA think it is risk free and do not consider what happens after the rental period is over, mistake #1.)
Every Dec they do a rental review, against other 4br houses not as a suburb average - and over the last 5 yrs every yr the rent has gone up ( Bonus #1). Like centrelink they pay every promised pay day even when vacant ( bonus #2)
We pay double what we pay in fees as we do to our other agents ( bummer #1), however when the tiles in the bathroom came off they fixed them, when the top of the cooktop was cracked they replaced I never pay for maintenace - which for all the others I have and do - 3 this month ( leaking DW, wobbly porch and new dryer)! And at the end of the lease they repaint and carpet. In my experience with older proeprties and my maintenance costs the 16.5% starts making me money after yr 3.( bonus #2)
About ten yrs ago I believe there prices were over market - and as a heads up if you have an older valuer sent out they will assume this to be the case - however I have only had 2 vals come in lower than asking price. Today DHA get independant valuations and if the property is not going to see a return for them they do not sell it and keep it under their ownership - so how do they make money and sell at market? - they buy in bulk.
Also if you look at the DHA houses in a development against others, DHA do not have sheets at the window they have blinds, they have a landscaped garden not dirt and they have a covered outside entertaining area - their standards are high - remember they pay for maintenance for the first 12 rys as well. ( bonus #3)
Here is a big heads up - REA rarely understand DHA properties and hence although you will find that they do not negotiate on new stock if a current vendor is selling not through DHA you can negotiate
but you have to sell with lease in place.
Anyhow in my experience DHA is similar to any other property purchase - you have to do your research. But the Govt and Aust defence force will still be about for yrs to come and they need somewhere to live.
Hope this helps
