in loan fee income, $88,000 in real estate owned activity, and $21,000 from other income. In addition, noninterest income decreased by $44,000 related to service fees on deposit accounts and $79,000 in income from bank owned life insurance.
Loan fee income was $190,000 and $138,000 for the three months ended September 30, 2010 and 2009, respectively, consisting primarily of late charge fees, fees from issuance of lines and letters of credit, and mortgage origination fees we receive on residential loans funded and closed by a third party. The $52,000 increase in loan fee income third quarter of 2010 compared to the same period in 2009 related primarily to the $63,000 increase in mortgage origination fees. Mortgage origination fees were $159,000 for the three months ended September 30, 2010 compared to $96,000 for the same period in 2009. Income related to fees received from the issuance of lines and letters of credit was $10,000 for the third quarter of 2010 and $12,000 for the third quarter of 2009, while late charge fees were $21,000 and $30,000 for the three month periods ended September 30, 2010 and 2009, respectively.
Service fees on deposit accounts consist primarily of service charges on our checking, money market, and savings accounts and the fee income received from client non-sufficient funds ("NSF") transactions. Deposit fees were $155,000 and $199,000 for the three months ended September 30, 2010 and 2009, respectively. The $44,000 decrease is primarily related to a $52,000 decrease in NSF fees and a $2,000 decrease in overdraft and returned item fees, partially offset by a $10,000 increase in deposit related fees such as service charges. Service charge fees were $77,000 and $67,000 for the three months ended September 30, 2010 and 2009, respectively, while other fees such as overdraft and returned item fees were $12,000 and $14,000 for the same periods in 2010 and 2009, respectively. NSF fee income was $66,000 and $118,000 for the third quarters of 2010 and 2009, respectively, representing 42.6% of total service fees on deposits in the 2010 period compared to 59.3% of total service fees on deposits in the 2009 period.
Income derived from bank owned life insurance was $134,000 and $213,000 for the three months ended September 30, 2010 and 2009, respectively. The $79,000 decrease in income from life insurance is due to reduced rates of return on the insurance policies due to the current market environment.
We recorded a $450,000 other-than-temporary impairment charge on one of our private-label collateralized mortgage obligations during the three months ended September 30, 2010.
Real estate owned activity includes income and expenses from property held for sale and other real estate we own, including real estate acquired in settlement of loans. For the three months ended September 30, 2010, our expenses related to the properties we owned exceeded income received on the real estate by $60,000.

In addition, the loss on the sale of real estate owned properties was $65,000 during the three months ended September 30, 2010. Comparatively, during the third quarter of 2009, income from real estate owned was $75,000 and expenses related to owning the real estate were $31,000. In addition, we recorded a $192,000 write-down on a property for a net loss of $148,000 for the three months ended September 30, 2009.
Other income consists primarily of fees received on debit card transactions, sale of customer checks, and wire transfers. Other income was $118,000 and $97,000 for the three months ended September 30, 2010 and 2009, respectively. The $21,000 increase related primarily to an $19,000 increase in debit card transaction fees and a $2,000 increase in other client service related fees. Debit card transaction fees were $88,000 and $69,000 for the three months ended September 30, 2010 and 2009, respectively, and represented 74.6% and 71.1% of total other income for the third quarters of 2010 and 2009, respectively. The corresponding transaction costs associated with debit card transactions are included in noninterest data processing and related costs. The debit card transaction costs were $35,000 and $27,000 for the three months ended September 30, 2010 and 2009, respectively. The net impact of the fees received and the related cost of the debit card transactions on earnings for the three months ended September 30, 2010 and 2009 was $53,000 and $42,000, respectively. Wire transfer and other deposit related fees were $30,000 and $28,000 for the third quarters ended September 30, 2010 and 2009, respectively.
As previously reported, on July 21, 2010, the U.S. President signed into law the Dodd-Frank Act. The Dodd-Frank Act calls for new limits on interchange transaction fees that banks receive from merchants via card networks like Visa, Inc. and MasterCard, Inc. when a customer uses a debit card. The results of this proposed legislation may impact our other income from debit card transactions in the future.
