I wrote a small tool that allows to compare different scenarios when borrowing money for buying real-estate.

There are a few parameters that can be set:

• How much money do I need?
• How much do I want to pay back every month?
• For how long is the interest rate fixed? (Longer fixing = higher rate)
• Am I planning to use unscheduled repayments? (Those are mandatory, but of course lower the cost of borrowing and shorten the time until you’re debt-free.)

The tool allows to compare different selections on three of those parameters (the loan sum is currently fixed).

Please try it out here and let me know if you like it!
