Analyze my Queens deal

[Jacqueline Pelzer]

Hi, I am newbie and I don't really know how to go about it here. I need help analyzing this deal: 3 family house in Queens (Bayswater near 5 Towns) Asking price: $518k Tax appraisal: $415k Taxes: will be $4,000 in 2017 3.5% down House: -- upper level 3 beds/2baths washer&dryer hookup -- ground level 3 beds/2baths with a finished half basement which has a half bath plus washer&dryer hookup -- basement level 2beds/1bath washer&dryer hookup Current rent roll for 3 spaces is appx $4,300 I'm planning on putting in an offer on it but I'm not sure what offer I should put. There's no chance I'd get an opportunity like this again. Can anyone make a suggestion? I'm thinking $500k to be competitive. This house is also not on the market yet. I've already had it inspected and the foundation and basement are sound with no issues.
