Why Uniform Mortgage Documents Matter
When you get a mortgage, you're not just signing any contract your lender happens to have. Fannie Mae requires specific, standardized documents called Uniform Instruments for every loan they'll purchase from lenders. These forms ensure consistency across the entire mortgage market.
Your lender must use the exact Uniform Instruments designed for your state and property type. A condo in Florida requires different paperwork than a single-family home in Texas. The standardization helps lenders sell loans to Fannie Mae and keeps the mortgage market functioning smoothly.
The documents include your promissory note (your promise to repay) and the security instrument (the document that gives the lender rights to your property if you don't pay). These aren't optional forms - they're mandatory for any loan that will be sold to Fannie Mae.
Required Documents for Different Property Types
Every mortgage starts with the basic Uniform Security Instrument and Note for your state. But depending on your property type, you'll need additional rider forms attached to these base documents.
For a condominium unit, your lender must attach Condominium Rider Form 3140. This rider addresses the unique aspects of condo ownership, like homeowners association fees and shared ownership of common areas.
Planned Unit Development (PUD) properties require PUD Rider Form 3150. Investment properties and 2-4 unit primary residences both need the 1- to 4-Family Rider Form 3170. Second homes get Second Home Rider Form 3890.
Say you're buying a condo as a second home. Your loan package would include the standard state security instrument, the standard note, the Condominium Rider Form 3140, and the Second Home Rider Form 3890. Missing any of these forms means your loan doesn't meet Fannie Mae requirements.
Version Requirements and Timing
The documents must be the current versions as of your note date - the date you sign your promissory note. Lenders can't use outdated forms, even if they're only a few months old.
This creates timing challenges during your loan process. If Fannie Mae releases updated forms between your initial application and closing, your lender must use the newer versions. This can cause delays if your lender prepared documents using older forms.
Your lender should verify they have the current forms shortly before closing. Fannie Mae publishes revision dates for all Uniform Instruments in Exhibit 4A of their guidelines, so there's no excuse for using outdated paperwork.
Special Requirements for Adjustable-Rate Mortgages
ARM loans require specialized ARM notes and ARM riders instead of the standard fixed-rate documents. These forms include specific blanks that must be filled in with your loan's interest rate terms.
The ARM documents come with some features "hard-coded" into the forms themselves, like the index used to adjust your rate and whether the loan is assumable. Other features are "soft-coded," meaning your lender fills in blanks with information specific to your loan.
For example, a 5/6-month SOFR-indexed ARM uses forms with the SOFR index and 6-month adjustment frequency already printed on them. But your lender must fill in your specific initial rate, rate caps, and adjustment dates.
Some states have their own versions of ARM notes. If you're getting an ARM in Alaska, Florida, New Hampshire, Puerto Rico, Vermont, Virginia, West Virginia, or Wisconsin, your lender must use the state-specific ARM note for that state.
Document Completion Requirements
The most technical part involves completing Section 4(D) of ARM notes, which sets the limits on interest rate changes. Your lender must calculate and insert specific numbers based on your loan terms.
The first blank requires the maximum interest rate for your first adjustment, calculated as your initial rate plus your initial cap. If you start at 4% with a 2% initial cap, this blank gets filled with 6%.
The minimum rate for your first adjustment goes in the second blank. This equals your initial rate minus the initial cap, but it can't be lower than your loan's margin. If your initial rate minus the cap would be 2%, but your margin is 2.5%, the lender must use 2.5%.
Common Problems and Delays
Wrong property type riders cause frequent delays. Lenders sometimes attach a standard single-family rider to a condo loan, or forget the second home rider when the property isn't your primary residence.
Version mismatches create another common problem. A lender might prepare documents using forms that were current when you applied, but Fannie Mae updated the forms before closing. The entire document package needs to be redone with current forms.
ARM loans face additional complications when lenders incorrectly complete the interest rate calculations in Section 4(D). Mathematical errors in rate caps or adjustment dates can require document re-preparation and delay closing.
Some lenders try to use Fannie Mae ARM instruments for Freddie Mac loans or vice versa. While this is sometimes allowed, it requires careful legal review to ensure the documents work properly for the specific loan program.
Additional Documentation for Special Loan Types
Certain mortgage products require additional documents beyond the standard Uniform Instruments. Texas Section 50(a)(6) equity loans need special Texas-specific documentation per [[4301.7]].
Construction-to-permanent loans and renovation mortgages require additional paperwork detailed in Chapter 4602. Government-insured loans like FHA, VA, and USDA have their own documentation requirements covered in Chapter 4205.
Manufactured home loans need specific documentation per [[5703.4]]. Community Land Trust mortgages require additional forms per Chapter 4502.
Your lender should identify any special documentation requirements early in your loan process. Waiting until shortly before closing to discover missing required documents can cause significant delays.

Mortgage instruments for ARMs
When closing ARMs, the Uniform Instruments used must be based on the applicable ARM product. Below are the required instruments and instructions for completing them.
(i)
Required ARM Uniform Instruments
ARMs must be closed using the Uniform Instruments for the applicable ARM product, consisting of:
ARM Note and ARM rider
– The Seller must use the most current version of the ARM Note and ARM rider.
The most current version of the Uniform Instruments is the version in effect as of the Note Date of the Mortgage. See
Exhibit 4A
for the current dates of revisions of all Uniform Instruments. See
Exhibit 5A, Authorized Changes to Notes, Riders, Security Instruments and the Uniform Residential Loan Application
, for authorized changes to the Uniform Instruments.
The ARM Note and ARM rider must be completed in accordance with the terms of the applicable ARM product. See
Section 4101.2(c)(iii)
for instructions for completion of Section 4(D) of an ARM Note.
Fannie Mae/Freddie Mac Security Instrument
– The Seller must use the most current version of the State-specific Fannie Mae/Freddie Mac Single Family Security Instrument prepared for use in the jurisdiction in which the Mortgaged Premises is located and the most current version of any applicable property type riders.
For certain ARM products, State-specific versions of the ARM Note have been prepared for Alaska, Florida, New Hampshire, Puerto Rico, Vermont, Virginia, West Virginia and Wisconsin. If a State-specific version of an ARM Note has been prepared, it must be used for ARMs secured by Mortgaged Premises located in that State. The multistate version of the ARM Note, with the required changes stated in
Exhibit 5A
, must be used in all other States.
Freddie Mac makes available Uniform Instruments for use with ARM products with various features.
The Uniform Instruments have the following features embedded in the form itself (hard-coded):
Assumability
The Uniform Instruments have blanks to be completed by the Seller for the following features (soft-coded):
Maturity Date (determines the term)
First Interest Change Date (determined by the Initial Period)
Maximum interest rate at the first Interest Change Date (determined by the Initial Cap)
Maximum increase or decrease in the interest rate at each adjustment after the first Interest Change Date (Periodic Cap); the Periodic Cap is hard-coded 1% for 30-day Average SOFR Index (SOFR)-indexed Assumable Life of Loan and Assumable after Initial Period with 45-day Lookback Period
Maximum interest rate for the life of the loan (Lifetime Ceiling, determined by the Life Cap)
Minimum interest rate for the life of the loan (Lifetime Floor, which must equal the Margin stated in the Note)
In determining which Uniform Instrument to use with each ARM product, the Seller must select the form with the applicable hard-coded information and complete the soft-coded information as appropriate. Because many of the features of an ARM product are soft-coded, the same Uniform Instrument may be used for different ARM products.
The 6-Month SOFR-indexed ARM Note and rider may be used with a 3/6-Month, 5/6-Month, 7/6-Month, and 10/6-Month SOFR-indexed ARM with the same Lookback Period and assumability period.
The Uniform Instruments may be used for ARM products that do not meet the eligibility requirements for sale to Freddie Mac. Freddie Mac encourages the Seller to use Uniform Instruments, if available, for originating ARM loans even if the ARM product is not eligible for sale.
The following table describe the Uniform Instruments available for different hard-coded features for ARM products:
Uniform Instruments for 6-Month SOFR-indexed ARM products by assumability period
3141*
3441*
3142*
3442*
Lookback = 45 Days Preceding the Interest Change Date
*Hard-coded with a 1% Periodic Cap

.
(ii)
Use of Fannie Mae ARM instruments
The Seller may use Fannie Mae’s ARM instruments only in accordance with the provisions of this subparagraph. The Seller must consult its own legal counsel when using a Fannie Mae instrument for a particular Freddie Mac ARM product.
The Seller originating ARMs on Fannie Mae instruments represents and warrants that the Fannie Mae instrument, when completed, is appropriate for the applicable Freddie Mac ARM product and can be serviced in accordance with the Guide.
(iii)
Instructions for completing Section 4(D) of an ARM Note
The Seller must complete Section 4(D), Limits on Interest Rate Changes, of an ARM Note as follows:
Insert in the first blank of the first sentence, referring to the Initial Cap (the maximum interest rate on the first Interest Change Date), the interest rate that is equal to the sum of the initial Note Rate for the Mortgage, plus the applicable Initial Cap for that ARM program
Insert in the second blank of the first sentence, referring to the minimum interest rate on the first Interest Change Date, the interest rate that is equal to the initial Note Rate for the Mortgage, minus the applicable Initial Cap. If this difference is less than the Margin stated in the Note, insert the value of the Margin.
Insert in the first blank in the last sentence, referring to the Lifetime Ceiling (the maximum interest rate during the life of the Mortgage), the initial Note Rate plus the applicable Life Cap for that ARM product
In the second blank in the last sentence, referring to the Lifetime Floor (the minimum interest rate during the life of the Mortgage), insert the Margin stated in the Note
