Hi,I am a 26 yr old who has been diagnosed with a mental disability.

The VA funding fee is waived is you have a service related disability of 10% or more. 

Even if they are on disability, once you're over 55, Social Security pretty much figures you're not going to be cured or rehabilitated.As far as medical issues or tenants passing away - I'd expect benefits to continue for someone with medical issues, and if they went into nursing home or hospital or passed away, you'd be dealing with evicting. 

Look for someone like me, who is retired or disabled on SSI, who can't earn much money in wages, or they can jeopardize their benefits.  

That being said I offer a grace period through the 5th so I don't have to hear about any complaints about when they get paid, when they get their disability check, a holiday, a weekend, etc.  

There are also some that are open to families, or just developmentally disabled, etc.Often, a city is trying to revitalize it's downtown area, and they partially fund, and get additional funding from the county, state, and even the feds. 

When I searched your link, it specifically states:"However, the landlord cannot base the difference in rent on the tenant's race, color, religion, sex, national origin, disability or family status.

I believe that just being obese may not be enough to protect them they may qualify for disability and that protect them. 

I rent in low-income senior housing, so just food for thought - if they're on Social Security of any kind, including disability, their money shows up like clockwork every month, so you don't have to worry about their source of income.You may need to work out rent payment options they're comfortable with, if they aren't internet savvy, as some seniors are not. 

Our S8 tenants are retired veterans on fixed income, retired seniors on fixed income, and people with qualified disabilities on fixed income.
