To buy a multifamily in short sale, don't know how to proceed

[Ling Chen]

Dear all,

I'm new to short sale. I saw online a few multifamily short sales in my area (nyc)  that I'm interested in viewing and buying. Some of the descriptions say you could only submit offer without viewing. How to submit an offer?

Could I give an offer lower than the asking price?

Is working with a short sale real estate agent a must in this case? If so, do you have a recommendation for new york city area?

Anything else I need to know for the deal to go through?

Thank you

Ling
