@Wayne Lee,
1st of all congrats on saving up the $80K. That's a great a start!
From what you've said here: "My risk tolerance is low and my emphasis is on cash flow. That may change as I gain experience. Despite the drawbacks of long-distance investing, I am leaning towards acquiring a multifamily in the Quad Cities or Cincinnati."
That to me sounds like the answer, you are probably just looking for confirmation.
I also read your push-back on finding a good property manager and that's what holding you back and you want to manage the property yourself. I highly recommend you ask your realtor or realtors for referrals on property managers and interview them. If you haven't checked it out, read David Greene's Book on long distance real estate investing. It gives you a step by step on how to interview property managers and find the right one. You can also leverage a property manager to confirm rents and demand for the property you are looking for.
I'm assuming you have a W2, you don't want to be managing properties as a side job, it's a headache. Leave it to a property manager who's full time job is managing properties, they have the expertise.
Remember this is your 1st deal, so you will have a lot of limiting beliefs that you'll use as an excuse to not invest. Step back, take a deep breath, thousands of people have figured out how to invest in real estate and go for it.
Good luck!
David
