Good question!  First, this is not legal advice, always consult a licensed and insured professional before making any decisions.  However, ALWAYS read the fine print.

In this case, with mortgage rates in the 4% range at the time of this writing, a 1.75% rate seems way too good to be true.

How can they do it then?

It’s likely an ARM (Adjustable Rate Mortgage), or a mortgage that has a variable percentage rate that tracks an index.  Or, it may have a balloon payment due at the end of a certain time period (e.g., a $50K payment due in one year, five year, etc.)

If it sounds to good to be true, it may be.

Questions, don’t hesitate to ask!
