Re:  NASB Financial, Inc.
     Form 10-K for fiscal year ended September 30, 2009
     File Number: 000-24033


Dear Sir or Madam:

The following are in response to the items noted in your
letter dated January 24, 2011:

1.  Please refer to our previous comment 1 in our letter
    dated November 18, 2010.  Please address the following:

    a.  Please tell us how you considered the guidance in
        ASC 820-10-35-51 when determining that a simple
        average was appropriate for determining the fair
        value of Central Platte.  Tell us how you
        reconciled the fact that they produced materially
        different results, both from each other and between
        reporting periods.  Please provide us your analysis
        supporting how you determined that this value was
        the most representative of the fair value of your
        investment and why you gave equal weight to methods
        2 and 3, specifically addressing how you considered
        the large difference between September 30 and
        December 31 and between the values produced by
        those methodologies and the appraisal obtained in
        March 2010, as adjusted.

    b.  Please disclose whether the appraisal obtained in
        March 2010 provided as is values, as completed
        values or both.

    c.  We note your disclosure beginning on page 36 of
        exhibit 13 of your 2010 Form 10-K.  Please revise
        to disclose specifically that you take a simple
        average of the fair value determined under each
        methodology used and disclose the fair value
        results of each methodology in enough detail for a
        reader to understand the potential variability in
        your fair value estimate.

    d.  Please tell us whether you have the right to compel
        Central Platte to sell undeveloped land.  Please
        clarify whether there are other contractual, legal
        or other restrictions that may hinder the sale of
        partially developed or undeveloped plots.

    e.  Please clarify why you used a different approach to
        value NBH give the similarity of the activities
        between the two entities.  Please tell us whether
        you have already received or plan to obtain an
        updated appraisal for this investment.  Please
        clarify why you did not utilize the updated raw
        land from the Central Platte appraisal considering
        the similarity and close proximity of the
        properties.  We note that you recorded a $1.1
        million impairment charge during the fourth quarter
        of 2010.  Please revise to disclose whether this
        was the result of an updated appraisal.  If not,
        please revise to disclose what assumptions changed
        in your valuation during that period that caused
        the large impairment.

Responses:

a.  The guidance within ASC 820-10-35-51-24 states that,
    "If multiple valuation techniques are used to measure
    fair value, the results (respective indications of fair
    value) shall be evaluated and weighted, as appropriate,
    considering the reasonableness of the range indicated
    by those results.  A fair value measurement is the
    point within that range that is most representative of
    fair value in the circumstances."

    As noted in our letter dated January 3, 2011, we
    measured impairment of our investment in Central Platte
    Holdings, LLC ("Central Platte" or "CPH") using four
    different valuation methods that incorporate third-
    party appraisals and a discounting of estimated future
    cash flows.  Method 1 presumes that the value for our
    interest in the entire property is derived from its
    total appraised value.  Method 2 uses the net present
    value of estimated future cash flows from:  a) the sale
    of the fully-developed lots, b) the development and
    sale of partially-developed lots, c) the operation of
    the Home Owners Association ("HOA") and maintenance of
    amenities, and d) the value of remaining raw ground as
    derived from a real estate appraisal.  This method
    presumes that our investment is first recovered from
    the future cash flows from lot sales and maintenance of
    amenities, then from the appraised value of the
    remaining raw ground.  Since the amenities have already
    been built in the subdivision, their valuation presumes
    a discounted cash flow for that which a wholesale buyer
    of the property would not otherwise be required to
    expend for such amenities, at a later date.  Method 3
    employs the same components, quantitative measures, and
    qualitative inputs as Method 2, but differs in the
    presumed timing of which portion of the property will
    provide cash flows first.  Specifically, it presumes
    that our investment will first be recovered from the
    portion of the property that is raw ground, and then
    from the net present value of estimated future cash
    flows from sales of the fully-developed and partially-
    developed lots, along with the operation of the HOA and
    maintenance of amenities over that time.  As with
    Method 2, the value of existing amenities is derived by
    discounting the estimated future cash flows that a
    buyer would not have to otherwise spend to add the
    amenities at a later date.  Method 4 uses a net present
    value of estimated future cash flows resulting from the
    sale of fully and partially developed lots, the
    operation of the HOA and related maintenance expense,
    plus estimated costs and income from the future land
    development and sale of lots from the portion that is
    currently raw land.

    Management continues to perform all four methods of
    valuation each quarter; however, because the estimated
    timeframe to "build-out" the entire subdivision in
    Method 4 exceeds 18 years, we believe the cash flow
    estimates for years 5 and beyond are too far into the
    future for their estimated values to be reliable.
    Therefore, Method 4 has been given zero weight in the
    final impairment calculation.  We have given valuation
    Methods 1, 2, and 3 equal weighting because we believe
    that one is not more plausible than the other.  It is
    our opinion that none of Methods 1, 2, or 3 are
    preferable, or more likely to occur, than the others.

    Although the results from all methods differ
    significantly, management believes this multi-faceted
    approach is reasonable given the highly subjective
    nature of the assumptions and the differences in
    valuation techniques that are utilized within each
    approach (e.g., order of distribution of assets upon
    potential liquidation).  In addition, given the fact
    that it is the intent of the members to continue to
    develop the partially developed and raw land owned by
    Central Platte, it is our opinion that a discounted
    cash flow method provides a more realistic estimate of
    value than merely an as-is appraised value.  However,
    given the high degree of uncertainty as to the timing
    of such cash flows, we believe that it is appropriate
    (and conservative) to weight the valuation method that
    utilizes only appraised value equal to the discounted
    cash flow methods.  The results from all four methods
    and our final analysis of value are provided below:

    It should be noted that the change in our final
    estimate of fair value from September 30, 2009, to
    December 31, 2009, was only a $1.17 million decrease,
    or 6.6%.  This decrease was primarily the result of a
    $900 per acre decrease in raw land values, which was
    supported by retroactively applying the "timing" factor
    utilized to adjust comparable sales in the third-party
    appraisal obtained in March 2010.  As with most
    appraisals, comparable land sale prices were adjusted
    either upward or downward, depending on various factors
    (i.e., timing, conditions of property, size, etc.)  As
    the appraisal was as of March 31, 2010, we evaluated
    the "timing" factor utilized to determine what the raw
    land value would be as of September 30, 2009.
    Retrospectively applying the monthly discount, used in
    the March 31, 2010, appraisal, back to September 30,
    2009, time period, resulted in an upward adjustment of
    approximately $900 per acre.  In addition, we increased
    the discount rate in Methods 2, 3, and 4 from 15% at
    September 30, 2009 to 18% at December 31, 2009.  This
    was commensurate with discount rates utilized by
    appraisers in our market during those time frames, and
    consistent with the discount rate utilized internally
    in evaluation of similar projects.

b.  The values presented in the appraisal obtained in March
    2010 for the Central Platte property were "as-is."

c.  The Investment in LLCs footnote in the Form 10-Q for
    the period ended December 31, 2010, was revised, to
    provide additional detail regarding our impairment
    analysis of Central Platte, as follows:

    The Company's investment in Central Platte consists of
    a 50% ownership interest in an entity that develops
    land for residential real estate sales.  Sales of lots
    had not met previous expectations and, as a result, the
    Company evaluated its investment for impairment, in
    accordance with ASC 323-10-35-32, which provides
    guidance related to a loss in value of an equity method
    investment.  The Company utilizes a multi-faceted
    approach to measure the potential impairment.  The
    internal model utilizes the following valuation
    methods; 1) liquidation or appraised values determined
    by an independent third party appraisal: 2) an on-going
    business, or discounted cash flows method wherein the
    cash flows are derived from the sale of fully-developed
    lots, the development and sale of partially-developed
    lots, the operation of the homeowner's association, and
    the value of raw land obtained from an independent
    third party appraiser; and 3) another on-going business
    method, which utilizes the same inputs as method 2, but
    presumes that cash flows will first be generated from
    the sale of raw ground and then from the sale of fully-
    developed and partially-developed lots and the
    operation of the homeowner's association.  The internal
    model also includes an on-going business method wherein
    the cash flows are derived from the sale of fully-
    developed lots, the development and sale of partially-
    developed lots, the operation of the homeowner's
    association, and the development and sale of lots from
    the property that is currently raw land.  However,
    management does not feel the results from this method
    provide a reliable indication of value because the time
    to "build-out" the development exceeds 18 years.
    Because of this unreliability, the results from this
    method are given a zero weighting in the final
    impairment analysis.  The significant inputs include
    raw land values, absorption rates of lot sales, and a
    market discount rate.  Management believes this multi-
    faceted approach is reasonable given the highly
    subjective nature of the assumptions and the
    differences in valuation techniques that are utilized
    within each approach (e.g., order of distribution of
    assets upon potential liquidation).  It is management's
    opinion that no one valuation method within the model
    is preferable to the other and that no one method is
    more likely to occur than the other.  Therefore, the
    final estimate of value is determined by assigning an
    equal weight to the values derived from each of the
    first three methods described above.

    As a result of this analysis, the Company determined
    that its investment in Central Platte was materially
    impaired and recorded an impairment charge of $2.0
    million ($1.2 million, net of tax) during the year
    ended September 30, 2010.

    The following table displays the results derived from
    the Company's internal valuation model and the carrying
    value of its investment in Central Platte at December
    31, 2010.  Dollar amounts are expressed in thousands.


    Method 1                                 $ 17,064
    Method 2                                   16,493
    Method 3                                   18,621

    Average of Methods 1, 2, and 3           $ 17,393
                                             =========

    Carrying value of investment in
      Central Platte Holdings, LLC           $ 16,405
                                             =========

    (It should be noted that we acknowledge the SEC's
    request to revise the Company's Form 10-K for the year
    ended September 30, 2010.  We received the comment
    letter on January 24, 2011, and our Form 10-Q for the
    period ended December 31, 2010, was filed on February
    9, 2011.  Based upon this timing, we made the decision
    to include this revision in the Form 10-Q in an effort
    to provide this information to investors in a more
    timely manner.)

d.  NASB does not have the right to compel Central Platte's
    managing partner to sell undeveloped land.  However, we
    do have the ability to exert significant influence
    given our 50% membership interest in the entity and
    that fact that NASB has funded all development costs to
    date.  There are no contractual, legal, or other
    restrictions that would hinder the sale of partially
    developed or undeveloped land owned by Central Platte.

e.  Although the NBH, LLC ("NBH") property is located
    within close proximity of the Central Platte property,
    the characteristics of the two properties and the
    activities of the entities are very dissimilar.  The
    approximately 1,200 acres owned by Central Platte is
    zoned for residential development, and CPH has been
    actively developing the first four phases of the multi-
    phase development since 2004.  The NBH property
    consists of 86 acres of raw ground zoned agricultural
    which fronts a major highway.  The highest and best use
    of this property will ultimately be for commercial use.
    This property is being held for future bulk-sale and is
    not generating an ongoing stream of cash flows.
    Therefore, an estimate of appraised value is the only
    valuation method used to measure impairment of this
    property.  The $1.1 million impairment charge recorded
    during the fourth quarter of fiscal 2010 was the result
    of independent third party appraisal performed as of
    that date.

    The following disclosure regarding the company's
    investment in NBH was provided in the Form 10-Q for the
    period ended December 31, 2010:

    The Company's investment in NBH consists of a 50%
    ownership interest in an entity that holds raw land,
    which is currently zoned as agricultural.  The general
    managers intend to rezone this property for commercial
    and/or residential development.  The raw land was
    purchased in 2002.  The Company accounts for its
    investment in NBH under the equity method.  Due to the
    overall economic conditions surrounding real estate,
    the Company evaluated its investment for impairment in
    accordance with ASC 323-10-35-32, which provides
    guidance related to a loss in value of an equity method
    investment.  Potential impairment was measured based on
    liquidation or appraised values determined by an
    independent third party appraisal.  As a result of this
    analysis, the Company determined that its investment in
    NBH was materially impaired and recorded an impairment
    charge of $1.1 million ($693,000, net of tax) during
    the year ended September 30, 2010.  No events have
    occurred during the three months ended December 31,
    2010, that would indicate any additional impairment of
    the Company's investment in NBH.  The carrying value of
    the Company's investment in NBH was $1.4 million at
    December 31, 2010.
