I can send you some brokers that I've used and refer out often for Ohio. 

Ensure they have robust risk assessment protocols in place.Ask how they assess borrower creditworthiness and property value.Examine Legal Documentation:Carefully review all legal documents, including loan agreements, investment agreements, and any other contracts you will be required to sign.Consider having a legal professional review these documents to ensure your interests are protected.Request References and Testimonials:Ask for references from other investors who have worked with the firm.

As far as lenders and agents, if the lender refers an agent to me do I have to use that agent or can I use a completely different agent then the one the lender tells me about?

@Scott Mac When you say sole proprietor are you referring to owning real estate in your name or as a single member LLC?

No one has more "skin in the game" than a PMC as they have to deal with the property every day until an owner sells or fires them.Also recommend finding your own Inspector and not one referred by an agent.

I invest here in Columbus, Ohio and I can help refer you the CORE 4 that you need: Agent, PM, Contractor, and Attorney.

This will allow you give a reference point on how much potential rent you can receive.

If it's a Mainstream bank like WF, BofA, Chase they'll likely be most worthwhile on a plain vanilla primary purchase, and provide a good frame of reference as you shop for mortgage options.

Which is why I've always referred to qualified buyers, and the agent can insist on a documented relationship (as a lawyer, I'm big on documentation) after the potential buyer is qualified.

Even then most refuse and refer you to heir lawyers.
