Property For sale. Tenant Occupied. Deal Breaker?

[Charlie Lopez]

I Would like to sell a 2 family property in Brooklyn with a tenant occuping the first floor. The issue is that the 1st floor tenants just moved in on the 1st of october. The owner would like to give the rent and security back before 30 days in order for the house to look more attractive to buyers or Investors. The owner is in pre-foreclosure and would like t sell now! What advice should I give him. Can the property stay occupied and still sell at a discount price? What advice would you give? Thanks all
