Real Estate Law USA.com

I have located a condo that I am interested in buying and plan to make an offer early next week. I have done some research on recent comps and have found the price to be very reasonable. The unit is being sold by a real estate broker who bought it as an investment property ~5 yrs ago. I’m trying to determine if I need a realtor. I was in the title/mortgage industry for 6 years, but this is my first home purchase. I am familiar with the process and have taken coursework in real estate law & was a licensed title agent. I plan to purchase a home inspection and know what contingencies I plan to ask for. Do I need a realtor at this point? I am familiar with purchase contracts; would it be odd for me to ask the owner to have his office draft a contract for my review? What if I had an attorney review it as well? Any thoughts? I want to close by mid-August and already have a mortgage approval (pending appraisal & title, of course). Thanks!
