how to pay loan 欢迎讨论

assume 30 year fixed, 5.75% interest rate.

if you bot a house for $400,000, and have $80,000 cash in hand, here are two scenarios:
1. you put $80,000 as downpayment and borrow 320,000 loan;
2. you put zero downpayment and borrowed 400000, but pay (one time) 80,000 extra to your principal the first time
you pay your mortgage.

Q1: which way is better?

I played a little bit using the following calculator, seems to me with #1 option, I pay a total
of 672277.79 + 80000; while with #2, I pay a total of 603453.89, a 150000 savings.

Of course, above assumption does not hold in realities, you have to pay higher interest rate zero downpayment. So

next question:

Q2: till how high of the interest rate, you still win with #2 option?

Using that calculator again, I found I almost always win (the calculator does not allow rate go above 25%).


但是, 如果你用#2, 你每月的月供增加了---对于 fixed rate, 你不能少付 mortgage.


好了, 我说的够多了, 你总共付的钱并不是唯一的判据. 大家讨论讨论吧.
