When I found out that they were charging interest daily, but there was no penalty for paying weekly, I broke my yearly payments into 52 smaller payments, and added $100 per payment. It was like we had a 15 year mortgage.

I actually got a call from the lender asking me what I was doing, lime I was doing something wrong. Turns out they were calling because they realized they weren't going to make the profit they expected from me.

I plan to pay off my mortgage between 3 & 5 years, because I bought WAY under what I could afford (the bank literally offered to lend me 3x purchase price).

Just curious, why weekly? I get paid biweekly and will partition my paycheck immediately. I hear a lot of people invest weekly and I think, are they paid weekly? 

 @86ee8b2c 

My mortgage charged interest daily, and I got paid weekly, so it worked out. 

If you do the math -- just run an excel spreadsheet -- you'll find your sweet spot. If you do a bi weekly payment, you can add an additional $50 to cover the interest charged in the week you don't pay, plus principal payoff

Ah, paid weekly, that makes sense.

Every day the money sits in your account and isn’t invested in either stocks, treasuries, or mortgage principal reduction, is a day of opportunity cost … at present interest rates, mortgage principal reduction is the “best” investment though it’s good to keep a cash reserve too
