Dear JL
The Australian Defence Force subsidise rents for pretty much all active defence force personnel. ADF personnel are free to organise their own accommodation and still receive the subsidy, I have had two ADF tenants and they have been excellent. The ONLY people who are grateful when you purchase a DHA property as an investment are the people running Defence Housing ( a "for profit business") DHA has taken a pro-active stance and actively promote DHA housing as a great investment. If you do the figures it is normally better for you to purchase an investment property, after doing all your research and due diligence, and renting it out either as self managed or with a rental agent/cy.
It has nothing to do with "Social Conscience" nor "Spousal Resentment". In fact if that's the way you think regarding your investments then DHA would love to hear from you.

Do not necessarily expect a good return on your investment

For me personally, and many ADF personnel, I'd rather buy a DHA property that was at the END of it's rental use as they are well maintained and a premium rent usually can still be had, and YOU the person taking the RISKS associated with this type of investment then reap all the rewards, as opposed to DHA gaining the benefit and you carrying the RISK

Finacial education, there is a reason it was never taught in school!
