A bridge loan is simple in principle and demanding on dates. I first confirm the sale is firm, then establish exactly how many days separate the two closings and how much has to be advanced. That’s what determines the cost.
An overlapping purchase and sale means two lenders, potentially two notaries, and dates that have to interlock. I make the whole thing hold together: the purchase financing, the bridge covering the gap, repayment at the sale. And I plan with you for the sale falling through anyway, because a transaction can collapse even after conditions are lifted.
