LoanReady — DSCR Calculator SaaS

Overview

LoanReady helps real estate investors calculate their Debt Service Coverage Ratio (DSCR) before meeting with lenders. Users upload bank statements and rental profit & loss statements; Claude Haiku extracts all transactions from the documents, computes the DSCR, and generates a lender-ready PDF report — in minutes.

What is DSCR?

DSCR = Net Operating Income ÷ Total Debt Service

Lenders use DSCR to assess whether a rental property generates enough income to cover its loan payments. A DSCR above 1.25 is typically required for DSCR loan approval. LoanReady lets investors know their number before they walk into a lender meeting.

How It Works

User creates an account (Clerk authentication)
Uploads bank statement or rental P&L as PDF
Claude Haiku reads the document and extracts transactions (date, description, amount, category)
System computes: Gross Rental Income → Net Operating Income → DSCR ratio
Stripe payment unlocks the full lender-ready PDF report
Report includes transaction breakdown, ratio visualization, and anomaly flags

Data Model

User — clerkId, email, linked to reports and subscription
Report — status, docType, grossRentalIncome, totalExpenses, netIncome, totalDebt, dscrRatio, paid, stripePaymentId, flags
Transaction — date, description, amount, type, category (child of Report)
Subscription — stripeCustomerId, stripePriceId, status, currentPeriodEnd

Key Design Decisions

Claude Haiku for extraction: Haiku is the fastest, most cost-efficient Claude model. PDF extraction is a structured task that doesn’t require deep reasoning — Haiku reliably pulls tabular data in a single prompt at under $0.01 per report.

Vision-based extraction: Claude reads the PDF visually, so scanned bank statements (image PDFs) work without a separate OCR layer.

Stripe gating: The DSCR computation runs for free; the lender-ready PDF download is gated behind a Stripe payment. This lets users see their number before committing.
