The owners are just getting up there in age and ready to retire.

I have a good amount of money in savings I feel for my age to buy a few houses now.

I try not to do messes up my age anymore!

For my applicants, I require at least the previous two years of addresses, with no gaps in residence, and I very carefully vet any "lived with family" claims if they are not college graduate age. 

At that age, time in> timing. 

I feel like people will not trust me because of my age and I also do not have a lot of money. and also what would i say to people who i would want to invest with me or have them lend me money.

I see alot of affordable manufactured homes (with land) for 55+ but is this a good age group for section 8 in the area?

Yes ,rent it to someone with 2 or 3 young boys around the age of 3 to 5 years old .  

At some point (either over time/age, or location) you have to make a decision to include a PM as another tool in your toolbox toward growing a profitable portfolio, and gaining your time back.
