Legality of requiring that potential tenants be disabled veterans

[Chad Huffer]

I've been thinking of setting up a deal offering free rent for a year to a disabled veteran and their family who are in need of help to regain financial stability; they would only be responsible for utilities and a small amount of money each month to cover property tax.  I'm not sure yet how I would get the referrals or get the word out but that shouldn't be a problem.

The question I have is:  Would it be legal to make this deal available to disabled vets only?

I've looked at the fair housing rules and it seem that I could do it since I would not be basing the decision on any of the protected group.

Of course before I go forward I would consult an attorney.

Any opinions?
