AI Analysis

●●SolidSolve My ProblemSlick

Real estate math with Zillow scraping and 5-year projections, but target audience is narrow.

Strengths
  • •20+ financial metrics + deal scorecard with real-time PDF export functionality
  • •Dual AI path: free local models (LM Studio/Ollama) OR paid (Claude) with SSE streaming
  • •Clever 4-strategy Zillow scraping (JSON + Playwright fallback) solves scraper blocking headache
Weaknesses
  • •Crowded category: BiggerPockets, REI.tools, other calculators already exist and dominate search
  • •Audience is niche (real estate investors); mainstream appeal is nearly zero

Post Description

Free, open-source rental property investment calculator. FastAPI backend (~1K lines) serves a single vanilla HTML/CSS/JS file (~2.8K lines) — no frameworks, no build step.

Calculates Cash-on-Cash, Cap Rate, DSCR, NOI, GRM, Break-Even Occupancy, and more. 14-point deal scorecard grades each metric individually. 5-year total return projection breaks down Cash Flow + Appreciation + Debt Paydown + Tax Benefits. Strategy fit analysis for Cash Flow / Wealth Building / Low Risk / BRRRR.

Optional AI analysis via LM Studio (free, local, GPU), Ollama (free, local), or Anthropic Claude (paid). Streaming responses via SSE with real-time filtering of thinking-model artifacts.

Zillow scraping with 4 extraction strategies for their __NEXT_DATA__ JSON + Playwright headless fallback when httpx gets blocked.

Save/compare scenarios, export PDF + HTML. MIT license.
