My other concern is that I don’t like tying up my money until almost age 60 & given the governments finances & what’s happening & about to happen to social security I don’t trust the Fed’s to even keep the Roth IRA benefits in tact to even the early adopters & others after it was promised too.

Like others have mentioned, mobile homes are low income housing and as long as people live on welfare, minimum wage, social security, etc.

In your neighborhood, you don't want to have a vacancy very long, because things can tend to 'go missing'.If one tenant has sufficient income to qualify based on your standards, but the (probably) student with no social (BTW, get a copy of their visa for your records, and proof they are a full-time student) does NOT have provable income or background, the ONLY way to go is to get first, last and security.Since you are living there, you will have a better handle on the day-to-day, and you MUST stay on top of things. 

Also social security number .

I've had it listed for rent for a couple of days now on a few rental sites, social media, etc, but have yet to have anyone come and look at it or inquire about it.

I'm currently interested in doing Wholesale, Flipping, Rehab while setting up Rentals for passive income in hopes to quit my brutal 9-5 that has taken over my time and social life.

If you can't donate maybe you could at least share it on your social media to help spread the word for this cause. 

If not, why have a 401(k) at all and not entirely rely on social security?

Fortunately social security for her children kicked in quick and she is able to afford the mortgage and living expenses however the family of her deceased husband took it upon themselves to file for the death certificate without her on it and send it off to the mortgage company.

Howeve, You may want to take a small salary to make sure you can get social security and Medicare if it’s still around when you are eligible.
