Most of the posts I've read here re: the supposed minimum salary requirements to live on Long Island 'without strugging', seem to be geared towards families with children, or young couples who will be having children in the future. I haven't seen any opinions about the 'minimum salary needed' for older couples (late 50s and older) who are in a different situation entirely.
In your opinion as a current Long Island resident: Would a couple whose income
AFTER TAXES is in the $45-50,000 range, their children grown and living elsewhere,
NO DEBT (
no mortgage, no auto loans, no credit card debt)
WHATSOEVER, no expensive vices

and who live a quiet stay-at-home lifestyle by personal preference, be able to afford to live in an all- or predominately-white upper middle class area of Suffolk County without 'struggling' as most people on this forum define that term? This presupposes property taxes of approximately $10,000/yr and home/auto insurance costs of approximately $5000/yr.
Logically this should seem quite possible to do on Long Island, given the conditions I describe above. Do you agree, and if not, please explain in detail why not. Thanks for all input!
