Pull all the comps that have sold in that neighborhood in the past three years. Take equivalent homes that have sold in the past year and deduct 30% (give or take). That’s what you should pay for the house.
Just because your “gut” says it’s a good deal doesn’t mean it is. Don’t fall into the “Costco Trap” in that just because you think you are getting a great deal because of the situation (aka being at Costco). Look at what the comps tell you.
