You can check out their thoughts on how to approach seller financing here: Making Your Primary Residence the BEST Investment Ever (Better BRRRR!) 

I am just starting my investment journey, so have only used Real Estate Agents to assist with buying and selling my primary residence. 

When I'm investing in trust deeds - my primary concern is the safety of the principal.

If they have Jr Coaches and they're your primary resource for coaching (and you're okay with that), ask them what the requirements/qualifications are for the JC's.

I’m trying to get a heloc or cash out refi on a primary residence duplex.l under FHA.I have great credit but modest incomeWife has bad credit with better income therefore I don’t believe we will qualify for heloc.Our plan was to get heloc to use as a down payment on another house hack or general investment property.So far our mortgage company said they could do the cash out refi which would raise our mortgage from $800 to $1200 (current rate is 3.62) and the rate would go to 6.6To pull out hopefully 30-35k maxMy concern is if I do the cash out.

So, if interest rates are a buyer’s primary roadblock, then I recommend negotiating a rate buydown at a seller’s expense or looking at new construction, where builders are offering rate reductions and other substantial incentives.What if I’m a seller?

Not a primary home, not a flip. 

@Nate Jenks no problem, here to help and clarify.When we speak to "cash out" loans in lending the maximum loan amount is usually 80% LTV on a primary home. 

I understand in most cases you do not want to be purchasing a second position DOT and I do thorough research.The primary DOT has not issued a notice of Trustee sale so the beneficiary has not attempted to foreclose.

I would be happy to connect you with him if you wanted to inquire further.I think 10% is as low as you will find for investment property, unless you purchase an SFR with an ADU or mother-in-law and house hack with a primary home loan.I hope that helps!
