Automate Affordable Housing Applications and Waitlists
AI reduces applicant response time by instantly calculating income and sorting applicants into AMI buckets. This replaces manual review, cutting response from days to seconds with automated email acknowledgments.
Syntora designs and builds custom AI automation systems to reduce affordable housing applicant response times. These solutions leverage advanced APIs like Claude and FastAPI to instantly calculate income, verify compliance, and sort applicants into appropriate AMI buckets. Syntora's approach focuses on a tailored engineering engagement, not an off-the-shelf product.
The system's scope depends on your property's compliance requirements and income verification process. Integrating with RealPage for a standard LIHTC property with paystub-based income is straightforward. A portfolio with HOME-layered units, asset verification triggers, and non-traditional income sources requires more complex logic. Syntora specializes in designing custom solutions tailored to these varying complexities.
What Problem Does This Solve?
Property management systems like RealPage and AppFolio are excellent systems of record, but they are not automation engines. Their application modules are simple web forms that create a digital file. They do not automatically calculate anticipated 12-month income from an hourly wage, tips, and commissions, nor do they sort applicants into the correct AMI tier. This forces your leasing team to become manual data processors.
A leasing agent for a 500-unit LIHTC lease-up receives 2,000 applications in the first week. For each one, they must download the PDF packet from AppFolio, open multiple paystubs, manually calculate projected annual income using a spreadsheet, look up the corresponding AMI percentage from a chart, and then tag the applicant's record. This process takes 20 minutes per applicant, creating a 600+ hour backlog instantly.
This manual bottleneck means qualified applicants at the top of the waitlist wait weeks for a response. During that time, they find other housing, and you are forced to move down the list to less-qualified candidates. The delay directly causes higher denial rates and longer vacancy periods because your first-choice applicants are gone by the time you contact them.
How Would Syntora Approach This?
Syntora would approach this problem by first conducting a detailed discovery phase to understand your specific compliance needs, existing workflows, and integration points with your property management system (RealPage or AppFolio). The initial technical step involves establishing secure API connections to your chosen PMS.
Webhooks would be configured to trigger a Python script hosted on AWS Lambda the instant a new application is submitted. This microservice would securely pull the applicant's submitted data and document attachments into a Supabase database, forming the foundation for processing. Client collaboration would be crucial for providing necessary API credentials and access during this phase.
For income document analysis, the system would utilize the Claude API to parse PDFs and images of paystubs, offer letters, and benefits statements. Syntora has extensive experience building robust document processing pipelines using Claude API for highly sensitive financial documents in adjacent industries, and the same rigorous pattern-matching and data extraction methodologies would be applied here. Custom Python logic would then be developed to apply LIHTC rules, accurately anticipating the next 12 months of income, annualizing variable sources, and performing checks for student status or asset verification triggers for HOME-funded units.
The calculated income would then be compared against the latest HUD AMI tables for your specific county, which would be dynamically loaded and maintained within a Supabase table. The system would automatically assign the correct AMI bucket (e.g., 30%, 40%, 50%, 60%, 70%, 80%). These results would be written back to custom fields within RealPage or AppFolio via their APIs, enabling automatic sorting of applicants into the appropriate waitlist.
Concurrently, a FastAPI service would trigger an automated email acknowledging receipt and providing a projected qualification status to the applicant. For operational robustness and clear insights, the system would incorporate structured logging with structlog and integrate with AWS CloudWatch for real-time alerts on API failures or processing anomalies, reflecting Syntora's standard engineering practices for ensuring reliability.
Depending on the complexity of your compliance requirements and existing systems, an engagement of this nature typically involves a 6-12 week build and integration timeline. Key deliverables would include a custom-built, deployed AI automation system tailored to your needs, full source code, and comprehensive documentation for ongoing support.
What Are the Key Benefits?
From Days to Seconds, Literally
Automated income calculation means applicants get a projected status email within 15 seconds of submission, not a week later.
Fill Units Faster, Stop Losing Leases
By eliminating the sorting bottleneck, leasing teams contact qualified applicants immediately, reducing vacancy loss which can cost over $2,000 per unit per month.
You Own the Code and the Logic
We deliver the complete Python codebase in your private GitHub repository. You are not locked into a proprietary SaaS platform.
Monitored 24/7 with Proactive Alerts
We use AWS CloudWatch to monitor every step. If an API connection to AppFolio fails, we receive an immediate alert and restore service.
Works Natively Inside RealPage
The system writes all data directly to custom fields in your existing PMS. Your leasing team never has to leave the software they already use.
What Does the Process Look Like?
Week 1: System Scoping and API Access
You provide API credentials for your PMS and 10-20 anonymized application packets. We deliver a detailed system architecture diagram.
Weeks 2-3: Core Logic Development
We build the income calculation and AMI sorting engine in Python. You receive access to a staging environment to test sample documents.
Week 4: Integration and Deployment
We connect the system to your live PMS instance and deploy it on AWS Lambda. You receive a runbook detailing the full production setup.
Weeks 5-8: Monitoring and Handoff
We monitor the system's performance on live applications for 30 days, making adjustments as needed. You receive weekly performance reports.
Frequently Asked Questions
- How much does a system like this cost to build?
- Cost is determined by the number of unique income document types and compliance rules (e.g., HOME-layered units vs. standard LIHTC). A typical build takes 4-5 weeks. After a 30-minute discovery call where we review your application forms and documents, we can provide a fixed-price proposal. Book a call at cal.com/syntora/discover.
- What happens if the AI miscalculates an income?
- The system flags any document it cannot parse with high confidence for manual review. This creates a task in your PMS for a leasing agent. This 'human-in-the-loop' design ensures edge cases are handled by your team without stopping the workflow. The AI accurately processes over 95% of typical applications automatically.
- How is this different from using RealPage AI Screening?
- RealPage's tool focuses on credit, criminal, and eviction history, not income qualification for affordable programs. It does not calculate projected 12-month income from paystubs or sort applicants into specific AMI buckets required for LIHTC and HUD compliance. Syntora builds the income qualification engine that works before the screening step.
- Where is sensitive applicant data stored?
- Applicant data is only stored temporarily during processing, which takes less than 15 seconds. Data is encrypted in transit and at rest using AWS KMS. Once processed, the results are sent to your PMS and source documents are purged from our system. We only retain an anonymized processing log for 30 days for debugging.
- Do we have to manually update the AMI tables each year?
- No. The system is built to automatically pull the latest income limits from the HUD API as soon as they are published. We build a simple interface where you can review and approve the new tables before they go live, ensuring your calculations are always based on the correct compliance data for your county.
- Can this handle a portfolio of properties with different rules?
- Yes. The architecture on AWS Lambda scales automatically. We can configure unique business rules and AMI tables for different properties within the same system. The system routes applications based on the property they applied to, applying the correct logic through a central Supabase configuration table.
