I thought about this long and hard when buying earlier this year. I could go either way, but chose the 20% down and large cash reserves to put in diverse investments.
I had no mort. before, so it was hard to fight the urge to put down a lot of money. It turns out my particular investments have always been over 10%. My jumbo was no points, no fees, 6.25%. This way I have years worth of payments if something bad should happen. The part of the money in Inet bank accounts provide 5.1% interest for high balances. I think AN’s numbers are in the ballpark.
Risk is everywhere. Who is to say the buyer in this post won’t do better in the long run than me?
PS. I have reasons for buying, don’t need to rehash.
