DIY mortgage refinancing (with some professional help):
The bottom line: If you’re mortgage is from 2008 and earlier you can save a significant amount of money
Cost – 2,000-3,000 NIS (not including early termination fee).
Time investment – 2-3 days of work, mostly in shorter sessions.
Total duration: about a month and a half.
