Peoples estimates on the $250K/year income and $200K down are pretty accurate.... but you probably need to up the $200K down to $300K down to make it work.
Why?
$200K down leave you with a loan of $800,000. This does not fall into the FNMA jumbo conforming guidelines, nor does it fit in the FHA jumbo guidelines. The moeny doesn't move fluidly above those guidelines (hell, even with those programs, people scoff at the 6.5-7% average interest reate you get on them.... for a 30 year fixed. They somehow expect to get awesome rates, like 5.5% or better... lol). Those programs cap at $729K... So on a million dollar property, if you want a 30 year fixed loan, expect to bring no less thatn $300K to the table.
$270K to get the loan amount down, and another 30K to handle out-of-pocket closing costs (title, escrow, probably gonna buydown that rate a bit, etc.).
Loans above that $729K cap just aren't going to be attractive to anyone who is in that position. Just my $.02.
