Selling off market, who would help me?

[Bill Ward]

My rental property is vacant and I'm doing repairs, expecting to sell when I'm done. I keep getting calls from investors trying to buy, but usually 75% of what I expect to sell with an agent ($190k vs $150k). I've never sold a house and I don't mind paying an agent's fee for their assistance, but the investor told me he would pay everything and I didn't need an agent. I feel like I should have an agent or a lawyer or someone smarter than me to help get through all the paperwork and the process to make sure I'm not getting the short end of the stick and looking out for my interests. Or is selling to someone like that really that simple as agreed price and sign?

Thanks
