Question regarding section 8 for old manufactured house(pre 1976)

[Kevin Kim]

Hello,

We have a property which has 2 old(pre 1976) manufactured houses in San Bernardino county California. We listed a rent on Zillow, and I got an inquiry from prospective tenants if we accept section 8.

I googled and I saw that there are  pros and cons. 
Some of the pros that I like is that they normally stay for many years, guaranteed to get paid, and we can get 20% more rent. 

Now, I have questions.

1. 1. Is a manufactured house which was built 1976 qualified for section 8? 
2. 2. I just wonder how it works at the tenants' side. Do tenants pay some portion of rent or do tenants pay nothing? 
3. 3. Does HUDd pay only rent or does HUD pay utility and renter's insurance too for tenants?
4. 4. Is renter’s insurance mandatory for section 8 tenants? I couldn’t find any insurance company who has renter’s insurance for our old manufactured house. 
5. 5. What’s the most that section 8 will pay? 
6. 6. The prospective tenant already knows how much we are going to rent the unit. Can we ask for more money?
7. 7. There is a storage unit that previous owners built which is connected to the house. And I’m pretty sure that it is not permitted. I heard that there will be Inspection. Do you think we have to remove the unit?
8. 8. I found there is section 202, something similar to section 8.
9. Please share what you think about section 8 and section 202.

it would be appreciated if you can answer some of my questions.

Thank you.
