Give me a museum and I'll fill it. (Picasso) Give me a forum ...
30 yrs is too long for us. We'd be locking up $$ until 83&89. I'm not planning to make it there. I suppose it could be a very long ladder position... 4.2% is just not enough for us to do it.
$500k would get you just over $20k income annually... If $500k is 3%ish, maybe. Also the state tax consideration, if you are in a state to consider.
If those same bonds would guarantee me 30 more years of life, I'd be all over them - even at 0%. Heh, heh, in 30, I'll be 106!!
