hi @Jessie Huffey I totally agree with @Robert Musallam and @Colin Smith
Disclaimer: I am licensed but don't do transactions for others. I only list my own properties. So I'm not a good candidate to list your property. And I'm not giving legal or professional advice.
You definitely want the exposure that the MLS will bring, along with the network and exposure that a good agent will bring to the table. I was taught very early on in my investing career from a multi-Millionaie real estate investor that thinking "that's expensive" is a consumer mentality. An investor should ask themselves a follow up question "compared to what?" 5-6% to a broker in your case is very inexpensive compared to the exponential expose, expertise, avoiding potential legal issues, holding multiple open houses, quick access to the property, qualifying buyers, potentially avoiding escrow fall out, etc that a GOOD or great agent brings to the table.
When I list my own properties or make offers on properties listed on the MLS, it still amazes me how much the sales price gets bid up to, usually way over what we initially thought. If the property is appealing to a typical owner occupant, you will likely cost yourself much more than 6% by trying to sell it yourself, especially remotely.
No offense. I say this with your best interest at heart. If I were in your shoes, I would get out of my own way, do what I do best and what makes me money. Let a professional do what they do best. Like a wise man named Jerry Macguire once said, "help me, help you". ;-)
I often follow my own advice, by offering other agents that bring me deals to list my rehabs on the back end. And I pay full commission, assuming there is room in the deal.
Best of luck on whatever you decide.
