Driveway Grade Too Steep

[Hunter L.]

I'm currently looking at a deal on a SFH that has a ridiculously steep driveway grade.

We tested the grade using a Jeep Grand Cherokee and the car got lifted up off it's back wheel trying to turn into the driveway. We were planning to fix and flip the property, but the cost to flatten the driveway out and add a retaining wall seems to kill the deal. Also, we believe it will be a severe deterrent to the end buyer if we don't fix it.

Does anyone have experience with flattening out driveways? What type of cost should you expect and are there any creative ways to deal with this or is it just a deal killer?
