Do I need to attorney to write an offer?

[Riaz Mohamed]

I am selling my home. I have listed the home on MLS through a flat fee listing agent, but I am representing myself in the sale process. I have been directly approached by an interested buyer who does not have a realtor. Given that there is no realtor on both sides, I need some help to write up the offer. Do I need to use a real-estate attorney or are there other options? What do you suggest, considering both quality and affordability in the process?

This is in Minnesota if that helps. Thank you in advance.
