I am self employed with two other businesses so the checkbook option shouldn't be a problem.I am looking at the following.iRA123 or Safeguard, Sense Financial, Broad Financial, and IRA financial group.If there are any better companies please let me know.

YUP  self serving  underhanded subliminal marketing attempt  dove tailing off he new crop of U tubers trying to convince investors that section 8 is a money train and the tenants are just so happy to have the voucher there is NOTHING they would ever do to lose it etc etc.In Jackson specifically they can trash the house and sec 8 WILL not take their voucher they just go on to the next landlord that just rehabbed a house and wants section 8 rent because market rate tenants in that city are some of the absolute worse payers in all the 25  markets I have worked over the last 22 years in the mid west and rust belt states and cities. 

If you end up starting your own business and getting out of your current job, you'll generally need to provide 2 years of self-employed tax returns to support your income.  

In my case, I have residential rentals in one LLC, commercial properties in another, self storage in a third, and my real estate company operates in a fourth.

We do Self storage so we use 90%.The lease is legal but you or your attorney need to vet it.  

You can find quality operators and leverage their expertise which allows you to be an investor in more than just multifamily - you can get into the other asset classes you mentioned - self storage, car washes and many many more!

Eventually, we became self-funded, so this isn't something I have any experience with. 

Do they allow self showings or require an agent to be present? 

Self-managing is a job.

In the past year I was able to turn our asset management and my primary development company both into self-managing companies.
