The word on the street is that it is very costly and a burden most renters cannot afford.

I know the lender is Citibank the deed is subject to their foreclosure but according to the tax records it's been in this stage for 6 years already.I want to purchase the place so I can eventually rent it out.

Also, even if the previous owner only owed 60k, you have to take into consideration the cost of foreclosing and the lost income if they hadn't been paying for months or years, not to mention any other costs of satisfying tax liens or maintenance issues that need to be resolved before sale.So, speaking as someone who has bought only 3 foreclosed properties:  You make an offer that works for you, and depending on how anxious they are to sell it, and how much interest they've had, they will accept or reject.  

Annual property taxes of $800-$1000. 

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?
