<p>I did verify something today.
If I mail in a $20,000 payment to my lender, and mark it “Principal Only”, my per diem interest will immediately go down from $17.25 to $14.91.
So at the end of 365 days, I will have saved $854.00
Now, do I really want to save $854.00 over a 12-month stretch? Since I see interest rates going up, and I am locked into a nice 4.25% apr, I may wait a bit, and put that $20,000 into a CD, where it would earn me the same interest, but be more accessible.</p>
<p>I am sure that the taxes lost on the CD interest would be pretty close to the deductions lost on the saved mortgage interest.</p>
<p>I don’t even make sense to myself
