I would suggest that your lease obligate the tenants perform small maintenance to the rental property, so long as it is safe for them to perform the repair and the repair is, by its nature, a minor repair that does not involve any special skills, tools, or licenses.

Is your "bird dog" supposed to find low income people and encourage them to sign up for Section 8?

The lender’s only collateral is the property itself.You’ll need a custodian that specializes in real estate IRAs and can wire funds, receive rent, and pay expenses directly from the account.

My question is whether that special type of sponsoring broker exists and what's the best way to find them?

What kind of RE investing are you two specialized in? 

Your bank SDIRA account is not suitable for real estate though, you would need to transfer this account to a company specializing in SDIRAs.But first decide on your plan.

Quote from @Jessica Duty: Does anyone have any recommendations for a local investor friendly realtor and also contractor in Rome, Ga area Hey Jessica,I am a native to Rome, GA and specialize in working with investors around the area.

Also RV repair is very, very expensive, specialized and depending on the season hard to schedule.Own a couple long term RV parks so here is some unsolicited advice.  1- Get out of the RV rental business. 

In Austin, there are a few channels that consistently produce off-market opportunities, whether you're targeting entry-level flips in 78745 or mid- to high-end areas like Jester, Westlake, or Barton Creek West.Some of the main sources I see working right now:• Driving for dollars in long-term ownership pockets• Pre-foreclosure + delinquent tax leads• Probate/inherited properties• Networking with local investors + RE agents• Builders offloading lots or heavy fixers quietly• Wholesalers who specialize in distressed or dated SFRs• Tracking aging or deferred-maintenance homesI’m in the Austin market daily and the deal flow has been all over the board lately — everything from heavy value-add homes to infill lots to luxury fixers.Curious what type of project you're aiming for — entry-level flip, mid-range, or something bigger?

For finding agents who specialize in working with out-of-state investors and off-market deals, networking is huge—connect with local investor meetups, join Ohio-focused Facebook groups, BiggerPockets threads, and reach out to agents who advertise themselves as investor-friendly or who have strong rental portfolios themselves.
