This applies to all 1-4 unit residential mortgages, whether first or later, and to borrowers as individuals, partnerships, LLCs, or corporations.
Originally, a law was enacted which prohibited deficiency judgments, but applied only to first residential mortgages by individuals.
This law may affect the bargaining position of homeowners with lenders regarding short sales, as it becomes a less attractive option for a lender where they are unable to get a deficiency judgment for the remaining amount of the loan. Many times lenders do waive this right, however, taking it off the table from the outset may be damaging to a homeowner's ability to procure the same, and further limits their options in foreclosure.
Although this law has not yet been enacted in NYS, California's enaction of the same, as well as the current state of the market and housing may appeal to NYS legislators and therefore it is something to keep an eye on into the future.
