OK here's a follow up question. She has a real buyer, who has offered 370-390K. The realtor met, says even with all the work that needs to be done with her house, it's closer to 420K in value. And that she should counter offer with a significantly higher number. And that she shouldn't be scared about scaring that guy off, because there are a lot of flippers who would be interested in her house.
In that situation, what number would you counter-offer with? The thing is, she really does need to sell her house. She can't afford a long drawn out process. Zillow estimate is a little over 430K.
