Wanting to sell as is in WI

So I want to do a fast sale of my single family house. It’s in bad shape and needs Many repairs; I am unable and unwilling to do anything about them.

I have spoken with two agents who also do flips and one knows of a person looking for a tear down to build in this area (highly desirable area). I have two parcels of land so someone could build quite a large house on the property.

I’m looking for advice on how to choose a realtor. I have never sold before and need to get the most money out of this as I can. I bought in 2017 for 100k and have a mortgage at 4 1/4%. I have around 80-85 left plus a heloc of 9500 plus some debts I need to pay off.

Any advice or suggestions would be most helpful.
