NOTES TO QUARTERLY PORTFOLIO OF INVESTMENTS

                        FIRST TRUST MORTGAGE INCOME FUND
                           JULY 31, 2012 (UNAUDITED)


                       VALUATION AND INVESTMENT PRACTICES

A. PORTFOLIO VALUATION:

The net asset value ("NAV") of the Common Shares of First Trust Mortgage Income
Fund (the "Fund") is determined daily, as of the close of regular trading on the
New York Stock Exchange ("NYSE"), normally 4:00 p.m. Eastern time, on each day
the NYSE is open for trading. If the NYSE closes early on a valuation day, the
NAV is determined as of that time. Domestic debt securities and foreign
securities are priced using data reflecting the earlier closing of the principal
markets for those securities. The NAV per Common Share is calculated by dividing
the value of all assets of the Fund (including accrued interest and dividends),
less all liabilities (including accrued expenses, dividends declared but unpaid
and any borrowings of the Fund), by the total number of Common Shares
outstanding.

The Fund's investments are valued daily in accordance with valuation procedures
adopted by the Fund's Board of Trustees, and in accordance with provisions of
the Investment Company Act of 1940, as amended (the "1940 Act"). The Fund's
securities will be valued as follows:

      U.S. Government securities, Mortgage-backed securities ("MBS"),
      Asset-backed securities ("ABS") and other debt securities are valued on
      the basis of valuations provided by dealers who make markets in such
      securities or by an independent pricing service approved by the Fund's
      Board of Trustees, which may use the following valuation inputs when
      available:

            1) benchmark yields;

            2) reported trades;

            3) broker/dealer quotes;

            4) issuer spreads;

            5) benchmark securities;

            6) bids and offers; and

            7) reference data including market research publications.

      Debt securities having a remaining maturity of sixty days or less when
      purchased are valued at cost adjusted for amortization of premiums and
      accretion of discounts.

In the event that the pricing service or dealer does not provide a valuation, or
the valuations received are deemed unreliable, the Fund's Board of Trustees has
designated First Trust Advisors L.P. ("First Trust") to use a fair value method
to value the Fund's securities. Additionally, if events occur after the close of
the principal markets for certain securities (e.g., domestic debt and foreign
securities) that could materially affect the Fund's NAV, First Trust may use a
fair value method to value the Fund's securities. The use of fair value pricing
is governed by valuation procedures adopted by the Fund's Board of Trustees, and
in accordance with the provisions of the 1940 Act. As a general principle, the
fair value of a security is the amount which the Fund might reasonably expect to
receive for the security upon its current sale. However, in light of the
judgment involved in fair valuations, there can be no assurance that a fair
value assigned to a particular security will be the amount which the Fund might
be able to receive upon its current sale. Fair valuation of a security is based
on the consideration of all available information, including, but not limited
to, the following:

       1) the fundamental business data relating to the issuer;

       2) an evaluation of the forces which influence the market in which
          these securities are purchased and sold;

       3) the type, size and cost of security;

       4) the financial statements of the issuer;

       5) the credit quality and cash flow of the issuer, based on the
          sub-advisor's or external analysis;

       6) the information as to any transactions in or offers for the
          security;

       7) the price and extent of public trading in similar securities (or
          equity securities) of the issuer/borrower, or comparable companies;

       8) the coupon payments;

       9) the quality, value and salability of collateral, if any, securing
          the security;

      10) the business prospects of the issuer, including any ability to
          obtain money or resources from a parent or affiliate and an
          assessment of the issuer's management;

      11) the prospects for the issuer's industry, and multiples (of earnings
          and/or cash flows) being paid for similar businesses in that
          industry; and

      12) other relevant factors.


                                                                          Page 7


NOTES TO QUARTERLY PORTFOLIO OF INVESTMENTS - (CONTINUED)

                        FIRST TRUST MORTGAGE INCOME FUND
                           JULY 31, 2012 (UNAUDITED)


The Fund is subject to fair value accounting standards that define fair value,
establish the framework for measuring fair value and provide a three-level
hierarchy for fair valuation based upon the inputs to the valuation as of the
measurement date. The three levels of the fair value hierarchy are as follows:

      o     Level 1 - Level 1 inputs are quoted prices in active markets for
            identical investments. An active market is a market in which
            transactions for the investment occur with sufficient frequency and
            volume to provide pricing information on an ongoing basis.

      o     Level 2 - Level 2 inputs are observable inputs, either directly or
            indirectly, and include the following:

            o     Quoted prices for similar investments in active markets.

            o     Quoted prices for identical or similar investments in markets
                  that are non-active. A non-active market is a market where
                  there are few transactions for the investment, the prices are
                  not current, or price quotations vary substantially either
                  over time or among market makers, or in which little
                  information is released publicly.

            o     Inputs other than quoted prices that are observable for the
                  investment (for example, interest rates and yield curves
                  observable at commonly quoted intervals, volatilities,
                  prepayment speeds, loss severities, credit risks, and default
                  rates).

            o     Inputs that are derived principally from or corroborated by
                  observable market data by correlation or other means.

      o     Level 3 - Level 3 inputs are unobservable inputs. Unobservable
            inputs may reflect the reporting entity's own assumptions about the
            assumptions that market participants would use in pricing the
            investments.

The inputs or methodology used for valuing investments are not necessarily an
indication of the risk associated with investing in those investments. A summary
of the inputs used to value the Fund's investments as of July 31, 2012, is
included with the Fund's Portfolio of Investments.

B. SECURITIES TRANSACTIONS:

Securities transactions are recorded as of the trade date. Realized gains and
losses from securities transactions are recorded on the identified cost basis.

Securities purchased or sold on a when-issued, delayed-delivery or forward
purchase commitment basis may have extended settlement periods. The value of the
security so purchased is subject to market fluctuations during this period. The
Fund maintains liquid assets with a current value at least equal to the amount
of its when-issued, delayed-delivery or forward purchase commitments until
payment is made. At July 31, 2012, the Fund had no when-issued, delayed-delivery
or forward purchase commitments.

C. REVERSE REPURCHASE AGREEMENTS:

Reverse repurchase agreements were utilized as leverage for the Fund. A reverse
repurchase agreement, although structured as a sale and repurchase obligation,
acts as a financing under which Fund assets are pledged as collateral to secure
a short-term loan. Generally, the other party to the agreement makes the loan in
an amount equal to a percentage of the market value of the pledged collateral.
At the maturity of the reverse repurchase agreement, the loan will be repaid and
the collateral will correspondingly be received back to the Fund. While used as
collateral, the assets continue to pay principal and interest which are for the
benefit of the Fund.


Information for the period ended July 31, 2012:

    Maximum amount outstanding during the period...................  $22,993,750

    Average amount outstanding during the period*..................  $21,990,894

    Average Common Shares outstanding during the period............    4,082,400

    Average debt per Common Share outstanding during the period....        $5.39



* The average amount outstanding during the period was calculated by adding the
borrowings at the end of each day and dividing the sum by the number of days in
the period ended July 31, 2012.

During the period ended July 31, 2012, the interest rates ranged from 0.31% to
1.97%, with a weighted average interest rate of 0.85%, on borrowings by the Fund
under reverse repurchase agreements, which had interest expense that aggregated
$144,410.

                           JULY 31, 2012 (UNAUDITED)


D. INVERSE FLOATING-RATE SECURITIES:

An inverse floating-rate security is one where the coupon is inversely indexed
to a short-term floating interest rate multiplied by a specific factor. As the
floating rate rises, the coupon is reduced. Conversely, as the floating rate
declines, the coupon is increased. The price of these securities may be more
volatile than the price of a comparable fixed-rate security. These instruments
are typically used to enhance the yield of the portfolio. These securities are
identified on the Portfolio of Investments.

E. STRIPPED MORTGAGE-BACKED SECURITIES:

Stripped Mortgage-Backed Securities are created by segregating the cash flows
from underlying mortgage loans or mortgage securities to create two or more new
securities, each with a specified percentage of the underlying security's
principal or interest payments. Mortgage securities may be partially stripped so
that each investor class receives some interest and some principal. When
securities are completely stripped, however, all of the interest is distributed
to holders of one type of security known as an interest-only or IO security and
all of the principal is distributed to holders of another type of security known
as a principal-only or PO security. These securities are identified on the
Portfolio of Investments.

F. INTEREST-ONLY SECURITIES:

An interest-only security ("IO Security") is the interest-only portion of a MBS
that receives some or all of the interest portion of the underlying MBS and
little or no principal. A reference principal value called a notional value is
used to calculate the amount of interest due to the IO Security. IO securities
are sold at a deep discount to their notional principal amount. Generally
speaking, when interest rates are falling and prepayment rates are increasing,
the value of an IO Security will fall. Conversely, when interest rates are
rising and prepayment rates are decreasing, generally the value of an IO
Security will rise. These securities are identified on the Portfolio of
Investments.


                                                                          Page 9

            240.13a-15(b) or 240.15d-15(b)).

      (b)   There were no changes in the registrant's internal control over
            financial reporting (as defined in Rule 30a-3(d) under the 1940 Act
            (17 CFR 270.30a-3(d)) that occurred during the registrant's last
            fiscal quarter that have materially affected, or are reasonably
            likely to materially affect, the registrant's internal control over
            financial reporting.
