The Biggest Financial & Operational Risks in Affordable Housing

For most affordable housing properties—particularly HUD Project-Based Section 8, PRAC, and other subsidy-dependent properties—the biggest combined financial and operational risk is weak compliance execution.

“In affordable housing, a compliance problem is rarely just a compliance problem—it can quickly become a cash-flow, occupancy, audit, and asset-value problem.”

The reason is simple: compliance is directly connected to revenue. HUD itself identifies inaccurate certifications/recertifications and voucher processing as financial risks that can result in owners being overpaid, while delays in subsidy processing can create cash-flow problems. TRACS applies automated controls to tenant certifications and voucher requests specifically to protect payment accuracy and program compliance. Below are examples of how compliance issues negatively impact a property from both a financial and operational perspective:

1. Staff turnover and insufficient expertise. Affordable housing has an unusually high knowledge burden. A new or poorly trained employee can make mistakes involving certifications, EIV, vouchers, waitlists, eligibility, rent calculations, or documentation that aren’t discovered for months. HUD specifically identifies new management, changes in key staff, and poorly trained staff as risk factors. This number one issue leads to a cascade of the rest identified below.
   1. 29.2% annual turnover: A recent real-estate industry survey found turnover among onsite property-level employees reached 29.2. Voluntary onsite turnover alone was 23.4%.
   2. 26% considering leaving the industry: NAA’s 2024 affordable-housing research found 26% of affordable-housing property management respondents planned to leave for another industry, compared with 15% in conventional multifamily.
   3. 50%–200% of salary to replace an employee: SHRM research estimates direct replacement costs can reach 50%–60% of annual salary, while the total impact of turnover can reach 90%–200% of salary after productivity losses and other costs are considered.
2. Occupancy & subsidy compliance failures — #1 risk. Incorrect certifications, missed recertifications, EIV problems, undocumented income/assets, TRACS errors, incorrect rents, or weak tenant files can lead to lost HAP, repayment obligations, findings, delayed vouchers, and subsidy adjustments. In serious cases, unresolved violations can lead to HAP payments being stopped.
   1. Documentation problems translate into real dollars. HUD’s FY2024 PBRA payment testing identified an estimated $45.2 million in “unknown payments” associated with insufficient documentation in the payment tier. These are dollars that HUD will try to pull back from properties in downward adjustments off vouchers if supporting documentation and corrections cannot be made.
3. Vacancy and poor occupancy management. Every vacant unit represents lost rental revenue/subsidy while many property expenses remain fixed. HUD’s own risk-monitoring guidance specifically identifies high vacancy as a property risk factor.
   1. Vacancy can have an enormous financial impact. A June 2026 HUD OIG audit found that the public housing agencies it reviewed lost the opportunity to receive operating subsidy and rental revenue totaling nearly $80 million in 2024 and more than $106 million in 2025 because of vacant units. OIG attributed vacancy problems in part to inadequate processes, management oversight, staffing/resources, and turnover delays.
   2. The math becomes compelling at the individual-property level. For example, if a 100-unit property generates an average of $1,200 per occupied unit per month, moving from 98% to 90% occupancy represents roughly:

      8 units × $1,200 × 12 months = $115,200 in potential annual revenue exposure.

4. Failure to capture all available revenue. This is the other side of compliance. Properties can lose substantial money through unresolved TRACS errors, missed adjustments, incomplete certifications, unclaimed special claims, delayed rent increases, or poor voucher reconciliation. A property can therefore be “compliant enough” to avoid a major finding while still leaving significant revenue uncollected.
   1. Special Claims can recover substantial vacancy losses. For eligible Section 8/202-8 properties, HUD allows regular-vacancy special claims of up to 80% of contract rent for as many as 60 days. For eligible Section 202/811 PRAC properties, the limit can be 50% of operating rent for up to 60 days.
      Example: Ten qualifying vacancies at $1,500 contract rent could represent up to $24,000 in potential Section 8 vacancy claims: $1,500 × 80% × 2 months × 10 units. If the property doesn’t properly process eligible claims, that potential reimbursement can be lost.
   2. Unpaid rent and tenant damages may also be recoverable. HUD’s Special Claims program permits eligible owners to seek reimbursement for former tenants’ unpaid rent, certain other lease charges, and tenant damages.
      Example: If a 150-unit property has 15 eligible move-outs during a year averaging $1,800 of qualifying unrecovered rent/damages, that’s $27,000 of potential exposure if nobody identifies, documents and submits eligible claims.
   3. Missing a rent increase compounds year after year. HUD programs provide mechanisms for annual rent adjustments; for example, eligible RAD PBRA HAP contracts receive annual OCAF adjustments, subject to program and contract limitations.
      Illustrative example: A 100-unit property at $1,200 average monthly contract rent has $1.44 million in annual gross rent potential. A missed 3% increase represents about $43,200 in the first year alone. Because the rent base carries forward, failing to maximize allowable rents can have a multi-year effect.
   4. Small HAP errors become large portfolio problems. PBRA and Tenant-Based Rental Assistance represented more than $50 billion of HUD expenditures in FY2024. HUD OIG specifically identifies the volume of payments, decentralized processing, differing processes and supporting documentation as payment-integrity challenges.
      At the property level, imagine a 150-unit property averaging $1,000/month in HAP. That’s $1.8 million of HAP flowing through the property annually. Even a 2% revenue leakage from unresolved errors, adjustments or missing subsidy would equal $36,000 per year.

The bigger business issue: These risks usually aren’t isolated.

Staff turnover → missed process → certification/file errors → TRACS/voucher problems → delayed or lost subsidy → cash-flow pressure → deferred operations → worse property performance.

That’s why the single biggest risk to an owner is losing control of the property’s compliance and revenue cycle.
