The Mortgage Insurance Loan Activity Report (MILAR) is the primary datacollection tool used by the Federal Housing Finance Agency (FHFA) and the Department of Housing and Urban Development (HUD) to monitor the performance of federallyinsured mortgage loans. The 32 designation refers to the standardized electronic format that lenders must use when submitting loanlevel activity for a given reporting period. By adopting a consistent template, agencies can aggregate, compare, and analyze millions of loan records, while lenders benefit from a clear, repeatable reporting process.
Key objectives of the MILAR32 Template include:
Because the template is mandatory for all lenders that originate or service federallyinsured mortgages, a thorough understanding of its structure is essential for both compliance officers and datamanagement teams.
The template is divided into logical groups that reflect the lifecycle of a mortgage loan. Below is a highlevel overview of each group and the most important fields within them.
| Field | Description |
|---|---|
| Loan Identifier (Loan ID) | Unique alphanumeric code assigned by the originating institution. |
| Origination Date | Date the loan was initially funded (MM/DD/YYYY). |
| Mortgage Insurance Certificate Number | Reference number of the insurance policy covering the loan. |
| Field | Description |
|---|---|
| Race/Ethnicity | Standardized code (e.g., 1White, 2Black, 3Asian, 4Hispanic, 5Other). |
| Sex | M for male, F for female, X for unknown. |
| Income Level | Annual household income bracket (e.g., 0$30k, $30k$60k, etc.). |
| Age at Origination | Borrowers age in years on the origination date. |
| Field | Description |
|---|---|
| Property Type | Singlefamily, multifamily (24 units), condominium, manufactured home, etc. |
| Occupancy Status | Primary residence, second home, or investment property. |
| Location | County and state of the subject property, using FIPS codes. |
| Appraised Value | Value determined by a licensed appraiser at closing. |
| Field | Description |
|---|---|
| Original Loan Amount | Principal balance at funding. |
| Interest Rate | Annual percentage rate (APR) expressed to four decimal places. |
| Loan Product | Fixedrate, adjustablerate, interestonly, etc. |
| Amortization Period | Number of months over which the loan is amortized. |
| LoantoValue (LTV) | Original LTV ratio, calculated as loan amount appraised value. |
| Field | Description |
|---|---|
| Insurance Premium | Total premium paid by the borrower, expressed in dollars. |
| Premium Funding Method | Paidupfront, financed, or split. |
| Coverage Amount | Maximum loss the insurer will cover, generally a percentage of the loan balance. |
| Insurer Identifier | Unique code assigned to the mortgage insurer (e.g., FHA, VA, Private). |
| Field | Description |
|---|---|
| Current Balance | Outstanding principal as of the reporting date. |
| Delinquency Status | 30, 60, 90day delinquency flag (Y/N). |
| Foreclosure Status | Indicates whether the loan is in foreclosure, REO, or normal. |
| Loss Mitigation Action | Details of any modification, repayment plan, or short sale. |
Before submitting a MILAR 32 file, verify each of the following items:
Failure to meet any of these criteria can trigger a submission rejection, leading to delayed reporting and potential regulatory penalties.
Adopting the MILAR 32 Template involves both technical and procedural changes. Below is a practical roadmap.
Identify source systems (loan origination, servicing, underwriting) and map each required field to the corresponding column in the template. Document any transformations (e.g., converting Yes/No to Y/N).
Build or configure a validation engine that runs the compliance checklist automatically. Most lenders embed this logic in an ETL (ExtractTransformLoad) workflow using tools such as SQL Server Integration Services (SSIS), Informatica, or Python scripts.
Generate a sample file for a single reporting period and submit it to the FHFA test environment. Review the validation report for errors and correct mappings accordingly.
Schedule the fullscale extraction after the quarter ends, run the validation engine, and produce the final pipedelimited file. Conduct a final checksum verification before upload.
Monitor changes to FHFA code sets and reporting dates each year. Update the datamapping documentation and validation rules promptly to avoid future rejections.
When lenders consistently deliver clean MILAR 32 data, the ecosystem gains several advantages:
Even experienced lenders encounter recurring issues. Recognizing them early can save time and money.
