We are downsizing our home to increase our buying power (and simplify life a bit).  We will be living in this property (3 bed, 1 bath, 1100 sqft) but have decided that whatever property we purchase will have the ability to cash flow if we need to live in a different property in the future. We are not attached to this house emotionally. So even though we are looking at it to live in we are evaluating it as a rental property. 

MY QUESTIONS - Fannie mae has asked for our highest and best by May 2nd, is there a strategy to win in this type of negotiation? What is a reasonable highest and best offer in this situation if we still want a decent ROI and Cash flow?
