What this overview covers
If you're financing a multifamily property with Fannie Mae and have been told your loan requires a Sponsor-Initiated Affordability (SIA) Agreement, you're operating under specific compliance obligations that come with the program — and you'll need to designate an Administering Agent to monitor and report on those obligations.
This overview is for borrowers and sponsors entering an SIA arrangement who want to understand what the program requires, what an Administering Agent does, and how we can help — either as your AA, as your compliance software platform, or both.
What is the Fannie SIA program?
A Sponsor-Initiated Affordability (SIA) Agreement is a commitment made by a borrower to Fannie Mae to maintain affordable rents on a defined portion of units within a multifamily property. In exchange, the borrower may receive more favorable loan pricing and underwriting terms.
SIA Agreements are part of Fannie Mae's broader mission to support the supply of affordable housing in the United States, and the program is governed by Fannie Mae's Multifamily Selling and Servicing Guide.
Once an SIA Agreement is in place, the borrower is responsible for keeping the committed units affordable for qualifying tenants throughout the term of the agreement. Compliance is monitored and verified by a designated Administering Agent.
This is not federal LIHTC and is not a state property tax abatement — SIA is a Fannie Mae loan-related affordability commitment. A property can sometimes carry multiple affordability programs, but the rule sets don't overlap automatically.
Who is required to have an SIA?
SIA Agreements are required by Fannie Mae for certain loan types and loan structures. Whether a particular loan requires SIA depends on the deal — your Fannie Mae lender is the operative authority on whether SIA applies to you.
In practice, SIA most commonly applies to borrowers who:
- Are financing a market-rate or mixed-income multifamily property with Fannie Mae
- Are receiving loan pricing benefits in exchange for an affordability commitment
- Have been informed by their lender that an SIA Agreement is a condition of the loan
The Administering Agent role
When you enter an SIA Agreement, Fannie Mae requires that compliance be periodically verified by a designated third-party Administering Agent — a qualified outside party responsible for reviewing your property's compliance records and certifying to Fannie Mae that the property is operating within the terms of your SIA commitment.
In practice, the AA's role is narrower than many borrowers initially expect: the AA performs an annual third-party compliance audit based on the records the borrower maintains throughout the year. The AA does not perform day-to-day compliance work — tenant qualification at move-in, ongoing recertification, and recordkeeping all sit with the borrower (or with whatever software platform or property management process the borrower uses).
General compliance posture
Because the Administering Agent verifies SIA compliance once a year, the day-to-day work that produces a clean audit sits with the borrower's team. At the highest level, SIA compliance requires four ongoing operational disciplines from the borrower:
- Tenant income qualification — verifying that tenants in SIA-restricted units meet the AMI restriction defined in the SIA Agreement at move-in
- Recertification — confirming continued qualification at recertification on the cadence required by the SIA Agreement
- Rent limits — keeping rent on SIA-restricted units below the AMI-tied ceiling defined in the agreement
- Documentation — maintaining a complete written record of qualification, recertification, and rent calculation for every SIA-restricted unit, sufficient to support the annual audit
These responsibilities sit with the borrower's compliance operation throughout the year. The Administering Agent steps in once a year to verify that the records demonstrate compliance and to certify the results to Fannie Mae. More on how we can support both layers below.
How we serve as your Administering Agent
We provide Administering Agent services for Fannie Mae SIA borrowers. As your AA, our role is to perform the annual third-party SIA compliance audit and certify the results to Fannie Mae:
- Annual compliance audit — we review your property's records for the SIA-restricted units, verify that tenant qualifications, recertifications, and rent limits are documented and within the terms of your SIA Agreement
- Verification of supporting documentation — we review the income certifications, lease records, and rent calculations the property has maintained throughout the year
- Fannie Mae compliance certification — we prepare and submit the required compliance certification(s) to Fannie Mae on the schedule defined in your SIA Agreement
- Findings and remediation guidance — if our review identifies a gap, we'll flag it and help you understand what remediation is required
What this doesn't include: the day-to-day compliance work that produces the records we audit — tenant qualification at move-in, recertification, ongoing rent and documentation management. That responsibility sits with the borrower. Most of our AA clients also use our SaaS platform to handle that work — see “Beyond SIA” below.
Beyond SIA: our compliance platform
The AA performs an annual audit — but as covered above, the day-to-day compliance work (tenant qualification, recertification, recordkeeping) sits with your team. Most of our AA clients also use our compliance software platform to handle that work.
The same platform extends to other compliance programs you may operate under, most commonly a state property tax abatement (North Carolina, South Carolina, or elsewhere). State abatement programs typically have stricter requirements than Fannie SIA, so the moment your team is set up to run state-program compliance, your SIA compliance is essentially handled in the same workflow.
Our SaaS platform takes the most repetitive parts of ongoing compliance off your team's plate:
- Compliance visibility — see your property's compliance picture across all units in real time, without spreadsheets to update or status meetings to assemble it
- Streamlined income document collection — send residents a structured income intake form in one click, then see real-time status so your team knows exactly who's complete, who's outstanding, and who still needs a follow-up
- Tenant qualification — We review each tenant's submitted income documents and determine AMI qualification, so your team isn't doing the math by hand (or second-guessing whether they got it right)
- TIC workflow — send, sign, and store Tenant Income Certifications (TICs) electronically, with a complete record attached to each lease
- Lease decisions with confidence — before signing a new lease or renewal, see exactly how it will affect your compliance picture
- Audit-ready documentation — every tenant's qualification, income documentation, and signed TICs are organized and accessible whenever you need them
If you operate properties under multiple programs, the same platform handles all of them — without rebuilding processes for each one.
Fannie SIA FAQ
- Do I have to use a third-party Administering Agent, or can I self-administer?
- Fannie Mae requires that the Administering Agent be a qualified third party. Self-administration is not permitted.
- What does an Administering Agent actually do?
- The AA performs an annual third-party audit of your SIA compliance, reviews the supporting documentation your team has maintained, and submits the required compliance certification to Fannie Mae. The AA does not perform day-to-day compliance work — tenant qualification at move-in, recertification, and ongoing documentation all sit with the borrower.
- How is an Administering Agent different from a compliance consultant?
- A compliance consultant typically advises — answering questions, reviewing your processes, training your team. An Administering Agent performs a specific role defined by Fannie Mae: an annual third-party verification of your SIA compliance, with a formal certification submitted to Fannie Mae. The AA role is defined by the SIA Agreement and Fannie Mae's program requirements; consulting engagements are defined by the client.
