Not trying to be discouraging, but this seems a bit overpriced for a 4 unit, mixed use property in Orange County. I have seen the values of several properties in the portfolio of commerical assets I manage in Orange County, NY drop drasically in the recent years.
Why the 30 day close? What is your role in the sale? Do you have the property under contract and you are wholesaling? Are you the current owner/landlord? It doesn't seem to me like anyone without cash will be able to close in 30 days, especially on a commercial property. And even cash buyers are going to need a period of due diligence...
