(b)   This security, sold within the terms of a private placement memorandum, is
      exempt from registration upon resale under Rule 144A of the Securities Act
      of 1933, as amended (the "1933 Act"), and may be resold in transactions
      exempt from registration, normally to qualified institutional buyers.
      Pursuant to procedures adopted by the Fund's Board of Trustees, this
      security has been determined to be liquid by First Trust Advisors L.P.
      ("First Trust" or the "Advisor"), the Fund's advisor. Although market
      instability can result in periods of increased overall market illiquidity,
      liquidity for each security is determined based on security specific
      factors and assumptions, which require subjective judgment. At July 31,
      2017, securities noted as such amounted to $6,723,138, or 10.28% of net
      assets.

(c)   Inverse floating rate instrument. The interest rate shown reflects the
      rate in effect at July 31, 2017.

(d)   This security, sold within the terms of a private placement memorandum, is
      exempt from registration upon resale under Rule 144A of the 1933 Act, and
      may be resold in transactions exempt from registration, normally to
      qualified institutional buyers (see Note 2C - Restricted Securities in the
      Notes to Portfolio of Investments).

(e)   Aggregate cost for financial reporting purposes, which approximates the
      aggregate cost for federal income tax purposes. As of July 31, 2017, the
      aggregate gross unrealized appreciation for all securities in which there
      was an excess of value over tax cost was $1,975,428 and the aggregate
      gross unrealized depreciation for all securities in which there was an
      excess of tax cost over value was $3,362,366.

IO    Interest-Only Security - Principal amount shown represents par value on
      which interest payments are based.

NOTES TO PORTFOLIO OF INVESTMENTS

                     FIRST TRUST MORTGAGE INCOME FUND (FMY)
                           JULY 31, 2017 (UNAUDITED)

                                1. ORGANIZATION

First Trust Mortgage Income Fund (the "Fund") is a diversified, closed-end
management investment company organized as a Massachusetts business trust on
February 22, 2005, and is registered with the Securities and Exchange Commission
under the Investment Company Act of 1940, as amended (the "1940 Act"). The Fund
trades under the ticker symbol FMY on the New York Stock Exchange ("NYSE").

The Fund is considered an investment company and follows accounting and
reporting guidance under Financial Accounting Standards Board Accounting
Standards Codification Topic 946, "Financial Services-Investment Companies."

                     2. VALUATION AND INVESTMENT PRACTICES

A. PORTFOLIO VALUATION

The net asset value ("NAV") of the Common Shares of the Fund is determined
daily, as of the close of regular trading on the 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 at market value or, in the absence of
market value with respect to any portfolio securities, at fair value. Market
value prices represent last sale or official closing prices from a national or
foreign exchange (i.e., a regulated market) and are primarily obtained from
third-party pricing services. Fair value prices represent any prices not
considered market value prices and are either obtained from a third-party
pricing service or are determined by the Pricing Committee of the Fund's
investment advisor, First Trust Advisors L.P. ("First Trust" or the "Advisor"),
in accordance with valuation procedures adopted by the Fund's Board of Trustees,
and in accordance with provisions of the 1940 Act. Investments valued by the
Advisor's Pricing Committee, if any, are footnoted as such in the footnotes to
the Portfolio of Investments. The Fund's investments are valued as follows:

      U.S. government securities, mortgage-backed securities, asset-backed
      securities and other debt securities are fair valued on the basis of
      valuations provided by dealers who make markets in such securities or by a
      third-party 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.

      Exchange-traded futures contracts are valued at the closing price in the
      market where such contracts are principally traded. If no closing price is
      available, exchange-traded futures contracts are fair valued at the mean
      of their most recent bid and asked price, if available, and otherwise at
      their closing bid price.

      Fixed income and other debt securities having a remaining maturity of
      sixty days or less when purchased are fair valued at cost adjusted for
      amortization of premiums and accretion of discounts (amortized cost),
      provided the Advisor's Pricing Committee has determined that the use of
      amortized cost is an appropriate reflection of fair value given market and
      issuer-specific conditions existing at the time of the determination.
      Factors that may be considered in determining the appropriateness of the
      use of amortized cost include, but are not limited to, the following:

      1)    the credit conditions in the relevant market and changes thereto;

      2)    the liquidity conditions in the relevant market and changes thereto;

      3)    the interest rate conditions in the relevant market and changes
            thereto (such as significant changes in interest rates);

      4)    issuer-specific conditions (such as significant credit
            deterioration); and

      5)    any other market-based data the Advisor's Pricing Committee
            considers relevant. In this regard, the Advisor's Pricing Committee
            may use last-obtained market-based data to assist it when valuing
            portfolio securities using amortized cost.

Certain securities may not be able to be priced by pre-established pricing
methods. Such securities may be valued by the Fund's Board of Trustees or its
delegate, the Advisor's Pricing Committee, at fair value. These securities
generally include, but are not limited to, restricted securities (securities
which may not be publicly sold without registration under the Securities Act of
1933, as amended (the "1933 Act")) for which a third-party pricing service is
unable to provide a market price; securities whose trading has been formally

                     FIRST TRUST MORTGAGE INCOME FUND (FMY)
                           JULY 31, 2017 (UNAUDITED)

suspended; a security whose market or fair value price is not available from a
pre-established pricing source; a security with respect to which an event has
occurred that is likely to materially affect the value of the security after the
market has closed but before the calculation of the Fund's NAV or make it
difficult or impossible to obtain a reliable market quotation; and a security
whose price, as provided by the third-party pricing service, does not reflect
the security's fair value. As a general principle, the current fair value of a
security would appear to be the amount which the owner might reasonably expect
to receive for the security upon its current sale. When fair value prices are
used, generally they will differ from market quotations or official closing
prices on the applicable exchanges. A variety of factors may be considered in
determining the fair value of such securities, 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
            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.

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
            investment.

The inputs or methodologies 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, 2017, is
included with the Fund's Portfolio of Investments.

B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME

Securities transactions are recorded as of the trade date. Realized gains and
losses from securities transactions are recorded on the identified cost basis.
Interest income is recorded daily on the accrual basis. Amortization of premiums
and the accretion of discounts are recorded using the effective interest method.

The Fund invests in interest-only securities. For these securities, if there is
a change in the estimated cash flows, based on an evaluation of current
information, then the estimated yield is adjusted. Additionally, if the
evaluation of current information indicates a permanent impairment of the
security, the cost basis of the security is written down and a loss is
recognized. Debt obligations may be placed on non-accrual status and the related
interest income may be reduced by ceasing current accruals and writing off
interest receivables when the collection of all or a portion of interest has
become doubtful based on consistently applied procedures. A debt obligation is
removed from non-accrual status when the issuer resumes interest payments or
when collectability of interest is reasonably assured.

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

                           JULY 31, 2017 (UNAUDITED)

of its when-issued, delayed-delivery or forward purchase commitments until
payment is made. At July 31, 2017, the Fund had no when-issued, delayed-delivery
or forward purchase commitments.

C. RESTRICTED SECURITIES

The Fund invests in restricted securities, which are securities that may not be
offered for public sale without first being registered under the 1933 Act. Prior
to registration, restricted securities may only be resold in transactions exempt
from registration under Rule 144A under the 1933 Act, normally to qualified
institutional buyers. As of July 31, 2017, the Fund held restricted securities
as shown in the following table that the Advisor has deemed illiquid pursuant to
procedures adopted by the Fund's Board of Trustees. Although market instability
can result in periods of increased overall market illiquidity, liquidity for
each security is determined based on security-specific factors and assumptions,
which require subjective judgment. The Fund does not have the right to demand
that such securities be registered. These securities are valued according to the
valuation procedures as stated in the Portfolio Valuation note (Note 2A) and are
not expressed as a discount to the carrying value of a comparable unrestricted
security. There are no unrestricted securities with the same maturity dates and
yields for these issuers.

D. FUTURES CONTRACTS

The Fund may purchase or sell (i.e., is long or short) exchange-listed futures
contracts to hedge against changes in interest rates (interest rate risk).
Futures contracts are agreements between the Fund and a counterparty to buy or
sell a specific quantity of an underlying instrument at a specified price and at
a specified date. Depending on the terms of the contract, futures contracts are
settled either through physical delivery of the underlying instrument on the
settlement date or by payment of a cash settlement amount on the settlement
date. Open futures contracts can also be closed out prior to settlement by
entering into an offsetting transaction in a matching futures contract. If the
Fund is not able to enter into an offsetting transaction, the Fund will continue
to be required to maintain margin deposits on the futures contract. When the
contract is closed or expires, the Fund records a realized gain or loss equal to
the difference between the value of the contract at the time it was opened and
the value at the time it was closed or expired.

Upon entering into a futures contract, the Fund must deposit funds, called
margin, with its custodian in the name of the clearing broker equal to a
specified percentage of the current value of the contract. Open futures contacts
are marked to market daily. Pursuant to the contract, the Fund agrees to receive
from or pay to the broker an amount of cash equal to the daily fluctuation in
value of the contract. Such receipts or payments are known as variation margin.

If market conditions change unexpectedly, the Fund may not achieve the
anticipated benefits of the futures contract and may realize a loss. The use of
futures contracts involves the risk of imperfect correlation in movements in the
price of the futures contracts, interest rates and the underlying instruments.

E. 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 and have the effect of
creating leverage. These securities, if any, are identified on the Portfolio of
Investments.

F. 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 security ("IO
Security") and all of the principal is distributed to holders of another type of
security known as a principal-only security. These securities, if any, are
identified on the Portfolio of Investments.

                           JULY 31, 2017 (UNAUDITED)

G. INTEREST-ONLY SECURITIES

An IO Security is the interest-only portion of a mortgage-backed security that
receives some or all of the interest portion of the underlying mortgage-backed
security 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, if any, are identified on the Portfolio
of Investments.

                           3. DERIVATIVE TRANSACTIONS

During the fiscal year-to-date period (November 1, 2016 to July 31, 2017), the
amount of notional values of futures contracts opened and closed in the Fund
were $10,124,388 and $8,271,185, respectively.





ITEM 2. CONTROLS AND PROCEDURES.

(a)   The registrant's principal executive and principal financial officers, or
      persons performing similar functions, have concluded that the registrant's
      disclosure controls and procedures (as defined in Rule 30a-3(c) under the
      Investment Company Act of 1940, as amended (the "1940 Act") (17 CFR
      270.30a-3(c))) are effective, as of a date within 90 days of the filing
      date of the report that includes the disclosure required by this
      paragraph, based on their evaluation of these controls and procedures
      required by Rule 30a-3(b) under the 1940 Act (17 CFR 270.30a-3(b)) and
