Most who do a short sale can receive $10,000 in relocation assistance once their short sale closes. There are two main programs for Relocation assistance, One is the HAFA program which is a government funded program where you receive $10,000 to move. The second program is through the state called Keep your Home California(KYHC).
This program allows sellers of a short sale to receive $5,000 in relocation assistance. Most of my clients that occupy their home receive one of the two of these programs. The last are lender based programs when the seller does not qualify for HAFA or KYHC but the lender gives cooperation money in order to complete the short sale. Many investor clients have received co-op payments even if they did not qualify for HAFA or KYHC.
