CO for two family? Taxed as a two family? Used as a two family? I guess it is a two family. Is the Highest and Best Use as a two family. That question can be tough to answer in certain parts of Brooklyn where two families are being converted into single family homes. Park Slope, Carroll Gardens, Brooklyn Heights, Bedford Stuyvesant. The lender can ask for anything they want, but you have the final decision. If Highest and best use is as a two family, personally I would use the multi family form, as it is best designed to present a clear picture of your subject. A one family form would need to many changes and additions to be useable and not misleading. Unlike the rest of these yahoos, James Micozzi and myself actively work in Brooklyn. If a lender insisted on a URAR, I would walk. Life is to short
