I don’t know if this makes me a radical communist or something, but in my opinion, if you’ve served in the military, especially if you’ve become disabled during your time, you shouldn’t get assistance paying for a house.
Your house should be bought and paid for. 110% subsidy, to help pay for things that will inevitably be imperfect with the property; electrical issues, corroded pipes, outdated HVAC, security, CO detectors, etc.
