Syntora designs and builds AI-powered systems for income verification in affordable housing. These systems leverage tools like the Claude API and FastAPI to parse documents and apply complex regulatory rules. Syntora offers engineering engagements to customize these solutions for specific property management workflows.

Syntora would design and build such a system specifically for affordable housing operators managing LIHTC, HOME, and HUD properties. This approach addresses complex income sources like hourly wages, tips, and commissions, calculating the required next 12-month projection. It also manages student status checks and asset verification triggers required for specific funding layers like HOME. The specific scope, including integrations and rule sets, would be determined through an initial discovery phase.

What Problem Does This Solve?

Manual income verification is the primary bottleneck in affordable housing leasing. A leasing agent opens dozens of PDFs per applicant, finds the pay rate, calculates an annual total from variable hours, and then manually tags the applicant in the property management system. This process is slow, inconsistent, and prone to calculation errors that lead to compliance issues and high denial rates after full file processing.

Property management platforms like RealPage and AppFolio are great systems of record, but their built-in tools do not automate the document-to-data workflow. They can receive an online application with attached paystubs, but an agent still has to open each file and perform the calculations. Their workflow tools lack the logic to anticipate 12-month income from non-traditional sources or automatically sort applicants into granular AMI tiers (30%, 40%, 50%) without manual tagging.

Consider a 500-unit new construction lease-up. The first wave of 100 units receives 1,500 applications. The RealPage portal collects them, but the team now has a queue of 1,500 folders to review. This creates a three-week backlog before they can even start contacting qualified applicants, causing good leads to drop out and delaying occupancy.

How Would Syntora Approach This?

Syntora would approach income verification automation by first conducting a detailed discovery of your existing workflows, specific compliance requirements, and desired property management software integrations (e.g., RealPage or AppFolio). This initial phase would define the precise data points needed, the specific LIHTC/HUD rules to implement, and the expected throughput.

The core technical architecture would involve a dedicated income verification engine. When a new application is submitted to your property management system, a webhook would trigger an AWS Lambda function. This function would retrieve the application data and associated documents, such as paystubs, bank statements, and offer letters. This method ensures direct data flow without manual exports.

We would use the Claude API to parse unstructured PDF and image files, extracting key data points like employer, pay rate, hours worked, YTD totals, tips, and commission structures. Syntora has built document processing pipelines using Claude API for financial documents, and the same pattern applies to these affordable housing documents. A Python script would then standardize this extracted data, for instance, converting a bi-weekly pay amount into an annualized figure based on established industry standards.

A Python calculation engine, hosted via FastAPI, would apply the defined LIHTC or HUD rules to anticipate the next 12 months of income. This includes annualizing hourly wages using the 2080-hour standard and projecting variable income based on historical data within the provided documents. The calculated total would then be checked against your property's AMI levels, which would be managed in a Supabase table. The system would then write the correct AMI bucket (e.g., '60% AMI') back to a custom field on the applicant's record in your property management software.

For operational visibility, the system would use structlog for structured logging. CloudWatch alerts would be configured to flag any document that the Claude API identifies with lower confidence, routing it for a quick manual review by your team.

A typical engagement for a system of this complexity involves a build timeline of 8-12 weeks, following an initial discovery phase of 2-3 weeks. The client would need to provide access to their property management software API, detailed compliance rules, and sample application documents for training and testing. Deliverables would include the deployed income verification system, comprehensive documentation, and knowledge transfer to your team.

What Are the Key Benefits?

  • Go From Application to Waitlist in 2 Minutes

    Eliminate the 40+ hour per week manual review bottleneck. The system processes and sorts a complete application in under 120 seconds, letting your team focus on leasing.

  • Pay Once for a System, Not Per User Forever

    This is a one-time build engagement with a minimal monthly hosting cost on AWS, typically under $50. No recurring per-seat SaaS fees that penalize you for growing your team.

  • You Own The Code and The System

    We deliver the complete Python codebase in your private GitHub repository. You are not locked into a proprietary platform and can have any developer extend it in the future.

  • Proactive Monitoring for 99.5% Accuracy

    We build in CloudWatch monitoring that alerts on parsing failures. Any document that cannot be processed automatically is flagged for manual review, ensuring high data quality.

  • Integrates Natively with RealPage and AppFolio

    The system uses official APIs to read application data and write back qualification status. Your team works within the software they already know, with no new dashboards to learn.

What Does the Process Look Like?

  1. Scoping & API Access (Week 1)

    You provide read/write API credentials for RealPage or AppFolio and your specific income calculation rules. We deliver a technical spec outlining the exact data flow and logic.

  2. Engine Development (Weeks 2-3)

    We build the core FastAPI application, Claude parsing module, and calculation logic. You receive a staging environment to test with sample applicant documents.

  3. Integration & Deployment (Week 4)

    We connect the engine to your live property management software and deploy the system on AWS Lambda. You get a deployment summary and access credentials.

  4. Monitoring & Handoff (Weeks 5-8)

    We monitor system performance and accuracy for 30 days, tuning as needed. You receive the full codebase, technical documentation, and a runbook for long-term maintenance.

Frequently Asked Questions

How much does a custom income verification system cost?
Pricing is based on the number of properties and the complexity of your income verification rules (e.g., handling HOME layers, student exemptions). A typical engagement is a fixed, one-time project fee with no recurring license costs. After a discovery call to review your specific requirements, we provide a detailed proposal with a firm price and timeline.
What happens if an applicant's paystub is a blurry photo?
The Claude API can handle many low-quality scans, but if it cannot extract data with high confidence, the system is designed to fail gracefully. It will halt processing for that specific applicant, flag their profile in RealPage or AppFolio for 'Manual Review', and send an alert to the leasing team. This prevents bad data from entering your system.
How is this better than using RealPage's document management features?
RealPage is an excellent document repository, but it requires your team to manually open each file and key in the data. Syntora builds the layer that reads the documents for you. It turns a passive storage system into an active processing engine, eliminating the manual data entry that creates bottlenecks and errors.
How do you ensure the privacy of applicant PII?
We build the system within your own AWS account, so you control the data. Applicant documents are processed in-memory and are not stored by the system after the data is extracted and sent to your property management software. All data in transit is encrypted using TLS 1.2, and we follow AWS best practices for IAM roles and permissions.
Who actually builds this system?
Syntora is a one-person consultancy. The founder, a senior engineer, is the person on your discovery call, the person who writes every line of code, and your direct contact for support. There are no project managers or offshore teams. This ensures deep technical ownership and clear communication throughout the build.
What if HUD or our state agency changes the income calculation rules?
The calculation logic is isolated in a specific Python module. When rules change, we update that single module, test it, and redeploy it. This typically takes a few days, not weeks. The architecture is designed for maintainability, so you are not stuck with a rigid system that cannot adapt to regulatory changes.
