Pledge agreement

The pledge agreement is an exchange of real estate in which the construction financing remains at the agreed terms. 
When is this an option? For example, if you own a home and must move for work reasons. Then you clearly need a new property. If you want to sell the old property, you can talk to your bank about continuing the current loan — just with the new property.  
Remember: The bank does not have to agree to a pledge agreement. And in all likelihood, it will not do so if it puts you at a disadvantage. But the chances are good if the new property is at least of equal value. Otherwise, the alternative would be to pay off the loan early — with the money you got from the sale — and pay an early repayment penalty.  
Although the pledge agreement is not free, the costs are usually lower.
