6 unit multifamily Apartment Purchase

[Aneisha Christie]

I am looking at purchasing a 6 unit apartment building in Brooklyn NY and the seller is willing to sell it at 475k!!! I do not see many lenders who I can go to for loan so I'm having trouble finding information. Also if I am living in one of the units, are there any incentives i.e. down payment help? I would be considered a first time home buyer being the last house I owned was 3 years ago. Does NY have any incentives for ppl like me wanting to buy a 6 unit? I guess I'm just looking for direction on how to go about this purchase
