A library of skills for commercial real estate due diligence and legal review. Each skill is a standalone workflow for a specific CRE task: rent roll audit, operating expense review, Phase I ESA review, ALTA survey and title commitment review, PSA clause-by-clause analysis, loan document review, estoppel certificate tracking, lease-to-system (Yardi/TRIRIGA/IWMS) reconciliation, and more. Works inside Claude, ChatGPT, Gemini, or any model that reads a system prompt. No API keys. No dependencies.
Each skill is a self-contained folder with a SKILL.md entry point, a README.md, a CHANGELOG.md, and supporting references/ files. Drop the ones you need into your own Claude Code setup — no orchestrator, no dependencies.
Every SKILL.md conforms to the open Agent Skills format — the same spec used by Claude, Cursor, VS Code, GitHub Copilot, Gemini CLI, and ChatGPT/Codex — so these skills work anywhere that standard is supported, not just in Claude Code.

submarket-study |
Structured submarket study covering rent positioning, comparable sales, supply pipeline, demand drivers, and market cycle position |
tenant-credit-and-exposure-analyst |
Evaluates tenant creditworthiness, concentration, and lease durability; tenant quality score, watchlist, and downside vacancy case |
psa-reviewer |
Clause-by-clause purchase and sale agreement review; annotated issue list covering contingencies, reps and warranties, and closing mechanics |
title-and-survey-reviewer |
Reviews a title commitment and/or ALTA survey; classified exception list, encumbrance impact analysis, and curative items |
loan-document-reviewer |
Reviews loan documents against the term sheet; term deviation report, covenant summary, and guaranty scope assessment |

Tracks estoppel certificate collection against the PSA threshold and verifies the insurance program before closing |
lease-to-system-auditor |
Compares executed leases and amendments against a lease administration or IWMS export (Yardi, TRIRIGA, Lucernex, MRI); every disagreement cited to clause and page |
| Skill | What it does |
|---|---|
acquisition-model-builder |
Builds a 5-year acquisition pro forma and runs a 27-scenario stress test for a multifamily or mixed-use acquisition; income waterfall, OpEx schedule, debt service, CapEx overlay, and returns (cap rate, IRR, equity multiple, DSCR, cash-on-cash, debt yield) |
scenario-stress-tester |
Runs 27 scenario permutations on an existing base case model, varying rent growth, expense growth, and exit cap rate; probability-weighted returns, best/worst cases, threshold stress tests, and variable sensitivity ranking |
ic-memo-writer |
Compiles a full investment committee memorandum from completed due diligence and underwriting outputs — executive summary, market and tenant analysis, financials, scenario results, risk assessment, and recommendation |
| Skill | What it does |
|---|---|
lender-sourcing |
Qualifies a deal against every lender category (Agency, CMBS, bank, bridge/debt fund), identifies 2-3 specific lender sources per qualified category, and produces a weighted-ranked lender package with a submission checklist |
quote-comparator |
Normalizes multiple lender quotes to a common basis and scores them on a weighted matrix (rate, leverage, flexibility, execution certainty, prepayment, timeline); ranks the top three with risk assessment and cost-of-capital impact |
term-sheet-builder |
Assembles a draft term sheet and financing recommendation from a selected lender quote — full loan terms, recalculated deal metrics, sources and uses, conditions and risks, and a legal review handoff |
Each skill works with Claude Code, Claude Projects, ChatGPT Custom GPTs, Cursor, Gemini, and any LLM tool that accepts a system prompt.
Claude Code expects each skill's SKILL.md one level directly under ~/.claude/skills/<name>/. Most skills in this repo sit right under skills/, but the underwriting/ and financing/ skills are one level deeper, so a plain cp -r skills/* would nest them too deep to be discovered. This installs every skill regardless of nesting:
git clone https://github.com/cre-ai-skills/CRE-AI-Skills.git
find CRE-AI-Skills/skills -name SKILL.md -exec dirname {} \; | while read -r d; do cp -r "$d" ~/.claude/skills/; donemkdir -p .claude/skills
cp -r /path/to/CRE-AI-Skills/skills/rent-roll-auditor .claude/skills/

claude --add-dir /path/to/CRE-AI-Skills/skills/underwriting/acquisition-model-builderOpen the skill's SKILL.md file and paste its contents into your project's custom instructions, system prompt, or knowledge base. Include the matching files under references/ if the skill calls for them.
