GEOGRAPHIC RESTRICTIONS • See Geographic Restrictions Matrix (Form 504) for location-specific geographic restrictions.
• If Choice Advantage, no Texas Home Equity (O/O Expanded Rate/Term, Debt Consolidation or
Cash Out).
• If Choice Advantage, maximum 80% LTV for New York properties on First Liens. (Note:
AuroraConnect does not support this eligibility item at this time. Please manually review all New
York property loans to ensure compliance with this geographic restriction.)
DOCUMENTATION • Full/Alt Doc and Reduced Documentation programs available. Reduced Documentation refers to loans
processed with income, employment and asset documentation which is more relaxed than traditional
FNMA or FHLMC Full Documentation requirements. Specific guidelines for each Reduced
Documentation type are outlined below.
• Full/Alt Documentation may be required if:
• The initial application is incomplete or missing from the submission package.
• Loan request is not commensurate with the borrower’s credit profile.
• Property is unique or otherwise has limited marketability.
• File contains documentation which suggests borrower’s income is not accurately stated on the
signed 1003 (i.e., bank statements showing payroll direct deposits with a deposit amount
significantly lower than that reported on the signed 1003).
• Files that do not have valid or usable credit scores.
• When applicable, income sources will be closely reviewed for reasonableness. If reasonableness cannot
be determined, Underwriting reserves the right to require documentation to support the reasonableness
(i.e., Underwriting may request: recent account statement to support assets available after closing to
generate stated interest income, evidence that an income-generating property is owned free and clear,
etc.).
Full/Alt Doc • Standard FNMA full or alternative documentation may be provided. Additional information can be found
in Underwriting Guidelines.
• Assets must be verified for reserves, closing costs, required down payment.
• IRS 4506 is required when tax returns are used to verify income.
• Verbal VOE required 5 days prior to closing for wage-earner income sources.
• Income, employment and assets are stated and verified.
• Liabilities are itemized and real estate owned stated.
Stated Doc • Income/Employment:
• Employment must be disclosed on the signed 1003 covering a two-year period.
• All income sources must be itemized on the signed 1003.
• Verification of income is not required.
• Income must be reasonable for employment disclosed.
• 5 days prior to closing: Verbal VOE required or if self-employed, an independent written
confirmation of self-employment is required (i.e., copy of business license, letter from CPA verifying

Negative Cash Flow
(For seasoning
requirements, see
LTV/CLTV/HCLTV
calculations below.)
The following policies apply to Mortgage Maker and High LTV Mortgage Maker only:
• Properties with negative cash are closely reviewed to ensure an overall acceptable risk.
• Cash flow for all N/O/O dwellings and O/O 3-4 unit dwellings is calculated as follows:
• Purchase transactions:
• Negative cash flow is the monthly rent minus expenses as evidenced by the FNMA 216 Form. If
expenses are outlined on Form 216 and deemed reasonable by UW due to net rent figure, do not
apply a standard 25% maintenance and vacancy factor. If unreasonable, use 25% maintenance
and vacancy factor.
• Refinance transactions:
• For properties that have been owned >12 months and where income is documented via tax
returns, cash flow will be based off of Schedule E.
• If property has not been owned for a full tax year or if income has not been documented via tax
returns, follow purchase transaction guidelines for the subject property.
• For O/O properties, the negative cash flow for purposes of the criteria listed below is calculated
assuming all units will be rentals. For DTI calculations, use only the negative cash flow or positive
cash flow associated with the actual rental units.
• If the N/O/O property or 3-4 unit O/O subject property is generating a negative cash flow, the following
restrictions apply:
• Full Doc: Eligible for maximum financing.
• Stated Doc and No Ratio:
• With at least 12 months PITI reserves, maximum financing is available. If less than 12 months PITI
reserves, financing is limited to the lesser of LTV permitted in matrix or 95% LTV/CLTV/HCLTV.
• Stated Income/Stated Assets and No Doc:
• Rate/Term and Expanded Rate/Term only (purchase, Debt Consolidation and Cash Out are not
allowed).
• Lesser of LTV permitted in matrix or 95% LTV/CLTV/HCLTV.
• Minimum 12-month history must be verified; see Credit topic, Underwriting Guidelines and Form 520
for additional information.
• Minimum ownership seasoning of 12 months.

only) loans: The score of the primary income borrower (occupant borrower who earns >50% of the
qualifying income) will be used for qualifying and pricing. If no occupant borrower earns >50% of the
qualifying income, use the lowest representative score of all borrowers. Credit of co-borrowers (but not
credit score) is expected to meet applicable requirements.
• A valid/usable credit score is one generated based on a minimum of 3 trade lines at least 2 or more years
old and accurately reflecting borrower’s credit history.
• Credit Report—3 file merged credit report or RMCR required.

Aurora) and pending transactions. In the event of a concurrent Piggyback transaction, the Piggyback and First
Lien loan will count as one loan. Maximum dollar thresholds still apply. Exceptions may be considered on a
case-by-case basis through the LPER process on Alt-A First Liens, excluding Alt-A High LTV loans.

SECTION 32 / HIGH COST
LOAN
Sellers are responsible for identifying loans that are considered high cost loans as defined by federal and/or state
laws and/or regulations. Aurora does not Purchase high cost loans as defined by federal regulations (Section 32)
and/or state regulations and, with respect to state laws and regulations, regardless of whether the lender would
be federally preempted or exempt from such laws or regulations. Upon delivery of all loans to Aurora, the Seller
represents and warrants:
• Loan is not a high cost loan as defined by Section 32 of the Federal Truth-in-Lending Act; and
• Loan is not a high cost loan as defined by applicable state laws and/or regulations; and
• Conforming loan amounts: Total points and fees may not exceed 5% of the loan amount. See Form 720 for
details regarding fees included in the 5% test; and
• Loans with original principal balance “OPB” ≥$75,000: Broker Compensation may not exceed 5% of the
OPB. Broker Compensation refers to fees paid to the Broker either by the Lender or directly by the
borrower, and often financed as part of the loan.

INTEREST-ONLY (I-O) OPTION
• The information outlined in this topic is specific to interest-only for all products except Choice
Advantage. For Choice Advantage, refer to the following Choice Advantage topics.
• Payments are interest-only for the first 10 or 5 years, as applicable, and fully amortizing for the remaining
term. No negative amortization.
• The interest-only monthly payment is calculated each month based on the current balance. If borrower
makes voluntary prepayments of principal during the Interest-Only Period, the subsequent monthly
payments will be based on the lower principal balance.
• Not available on loans with a temporary buydown.
• ARM Loans use Form 603E to amend the ARM note and 603F to amend the ARM rider to the security
instrument (See Forms TOC and Section 6 for additional details).
I-O ELIGIBILITY Period Alt-A/High LTV Alt-A, Mortgage Maker/High LTV Mortgage Maker (If applicable, see
Choice Advantage topic for I-O features)
5-year I-O Period 30-year fixed-rate only
10-year I-O Period All products with a 30-year term
CHOICE ADVANTAGE The Choice Advantage product allows for four payment options during the early years of the loan. This is
known as the Option Period. The Option Period begins on the date of settlement and remains in effect
for 60 months, or until payment of the minimum payment on the next scheduled payment date would
cause the principal balance to exceed 115% of the original loan balance, whichever is earlier. The
interest rate will not change during the Option Period.
After the Option Period, the minimum monthly payment will be interest-only based on the note rate and
current unpaid balance. The interest-only period will continue through the 10th year of the mortgage
loan.
Beginning in the 11th year of the loan, the borrower will begin making payments of principal and interest
sufficient to amortize the loan over the remaining term of the loan.
Choice Advantage During
Option Period
During the Option Period the borrower will have the option of paying one of the following monthly
payments:
• Option 1– Minimum Payment:
• A minimum payment of interest-only calculated based on the original loan amount and a rate
that is 3, 3.5 or 4 percentage points below the note rate. The result of this calculation is called
the minimum payment provided the negative amortization balance cap has not been reached.
This minimum payment will remained fixed during the Option Period.
• The required minimum payment is determined based on one of the following alternatives, with
minimum qualifying criteria listed under each. Please note: The borrower may choose (one
time choice) a higher minimum payment than that which he or she qualifies for. For example,
even if the borrower qualifies for the note rate minus 4%, he or she may choose one of the other
two payment alternatives:
• Note rate minus 3%; interest-only payment:
o This is the standard payment option; however, the following alternatives are available
based on the applicable occupancy and credit score criteria.
• Note rate minus 3.5%; interest-only payment if the borrower meets the following criteria:
o Full Doc, owner occupied, with a credit score of 700-719
o Stated Doc, owner occupied with a credit score of 720-739
• Note rate minus 4%; interest-only payment if the borrower meets the following criteria:
o Full Doc, owner occupied with a credit score of ≥720
o Stated Doc, owner occupied with a credit score of ≥740
• Option 2– Interest-Only:
• An interest-only payment calculated at the note rate based on the unpaid principal balance. This
payment may vary based on the unpaid balance each month.
• Option 3– P&I based on remaining term:
• A fully amortized payment based on the unpaid balance and the actual remaining term to
maturity. This payment may vary based on the unpaid balance each month.
• Option 4– 15-year P&I Payment:
• A fully amortized payment based on the current unpaid balance and a 15-year term to maturity.
This payment may vary based on the unpaid balance each month.
Choice Advantage After
Option Period
• Interest-Only Period
• After the Option Period, the borrower will be required to make a monthly payment sufficient to
pay the interest due on the unpaid balance. This new payment may be significantly higher than
the minimum payment required during the Option Period.
• The interest-only monthly payment is calculated each month based on the current balance. If
borrower makes voluntary prepayments of principal during the Interest-Only Period, the
subsequent monthly payments will be based on the lower principal balance.
• The Interest-only period will continue through the 10th year.
• Rate and payment may change on each Interest Rate Change Date.
• Full Amortization Period
• Beginning in the 11th year, the borrower will be required to make monthly payment sufficient to
repay the principal and interest over the remaining term of the loan.
• Rate and payment may change on each Interest Rate Change Date.
Choice Advantage
Negative Amortization
• The only program that allows negative amortization is Choice Advantage. Alt-A, High LTV Alt-A,
Mortgage Maker and High LTV and Mortgage Maker do NOT allow negative amortization.
• Choice Advantage negative amortization cap is 115%. If unpaid balance increases to 115% above
the original principal balance, the loan will be recast to an interest-only loan (see After Option Period
topic above).

PREPAYMENT PENALTY • Permitted on transactions in accordance with state-specific restrictions as outlined on Form 603A
• Form 603A includes instructions, legal documentation requirements and state restrictions.
• The prepayment penalty feature is an option, not a requirement. If prepayment penalty feature is selected,

Special Disclosure Aurora Form 480E, Choice Neg Am 5/6 Aurora Form 481E, Choice Neg Am 5/1
Due to the complex features of the Choice Advantage 5/6 and 5/1 ARMs, Aurora has developed special disclosures that
must be given to the borrower. These disclosures go beyond Regulation Z requirements by addressing payment shock,
providing a detailed explanation of negative amortization, and presenting payment examples. This disclosure or a similar
disclosure is required. If an alternative version is provided, the Client must Represent and Warrant that all product
descriptions and disclosures were given to consumers in advance of closing, containing information about the costs, terms,
features and risks of the product, including without limitation the following:
(a) Payment Shock. Consumers have been informed in writing of the potential increases in payment obligations,
including circumstances in which negative amortization reaches the contractual limit.
(b) Negative Amortization. Consumers have been informed in writing about the potential for an increasing principal
balance and decreasing home equity, as well as other potential adverse consequences of negative amortization.
(c) Option Period. Consumers have been informed in writing about the option period and when the option period ends
(60 months or when negative amortization cap is reached).
This representation and warranty will be waived on all loans closed using Aurora-specific disclosures.
Note: Clients may attach Form 485 to their disclosures to address Payment Shock, Negative Amortization and the Option
Period.
