I've got excellent credit at the moment and a job with six figure income (however much lower after taxes/student loans/primary mortgage), would this help gain what I want with a lender?

But be careful of the taxes eroding any possible cashflow. a 60k property in Coram, NY will run you 5600 in taxes, so this appears to be a challenge even in suffolk.

How much should I reasonably expect to pay in state and federal tax?

Who's been paying property taxes and insurance all these years?
