Septic capacity in New York State

[Jerome Maisch]

Hi BP community! My wife and I are in contract for a 4bd house built in ~2010 in NY for which we learned that the septic is 1bd capacity. The sellers bought it as a foreclosure but were aware that the septic had to be changed for other reasons (metal tank as previously used for trailers) so they are agreeing to do a 30K escrow/ credit. As we're out of compliance what are the consequences if we buy that house, could we have a denial of occupancy right?
