Rent vs Buy Decision Engine
Stop guessing on rent vs buy. Get your data-driven decision in 10 minutes.
What You Can Do
This skill runs rigorous financial analysis on your specific situation, calculating break-even points, NPV, IRR, and long-term wealth impact while factoring in behavioral and lifestyle considerations that pure math misses. You get a clear recommendation backed by numbers, scenario comparisons showing what happens if markets shift, and a detailed breakdown of when buying becomes better than renting.
Features
Calculate exactly when buying pays off compared to renting, accounting for down payment, closing costs, property appreciation, and rental inflation.
See the net present value of buying vs renting over 5, 10, and 30-year horizons, plus internal rate of return on your equity investment.
Test what happens if home prices rise 2% annually instead of 3%, if rates fall, or if you stay only 3 years instead of 10. See how sensitive your decision is to market changes.
Account for life stability, risk tolerance, flexibility needs, and lifestyle preferences that pure financial analysis ignores but actually matter to your happiness.
Compare rent-to-price ratios and affordability across neighborhoods or cities to identify the best markets for your timeline and budget.
Factor in mortgage interest deductions, property tax benefits, capital gains implications, and state-specific tax advantages automatically.
Get a clear recommendation (Rent Now, Buy Soon, or Buy Now) with confidence level and specific go/no-go triggers based on your inputs.
Visualize your projected net worth by age 65 under both scenarios, showing cumulative impact of your rent vs buy choice over your lifetime.
Example Output
Example 1: First-Time Buyer in Austin, TX
Input: Salary $95K, $80K saved, considering 3-bed house at $425K vs renting similar for $1,800/mo
Output:
- Break-even point: 5 years, 4 months
- 10-year NPV of buying: +$127,400 (buying wins by $127K)
- IRR on equity: 8.2% annual return
- Recommendation: Buy Now (Confidence: 92%)
- Market volatility: Even if prices drop 15%, you still break even in 6.8 years
- Wealth at 65: Buying gains $340K more than renting
Example 2: Corporate Relocatee with 2-Year Horizon
Input: Considering $650K home, 4% down, staying 2 years, then relocating
Output:
- 2-year break-even: NOT MET (buying costs $48K more)
- Recommendation: Rent Now (Confidence: 88%)
- Why: Closing costs, realtor fees, and market appreciation insufficient for short hold
- Go/No-Go Trigger: If you decided to stay 4+ years, recommendation flips to Buy
Example 3: Investment Property in Denver
Input: $500K property, 25% down, rent projects $2,400/mo (5% yield)
Output:
- 10-year IRR: 7.8% (beats S&P 500 average)
- Cash-on-cash return Year 1: 6.2%
- Break-even on appreciation: 3.2 years
- Tax-adjusted NPV: +$94,200 after depreciation benefits
- Recommendation: Buy as Investment (Confidence: 85%)

You can conduct comprehensive security audits of Solidity smart contracts by submitting code for systematic analysis across vulnerability categories, gas optimization, and best practice compliance. Claude identifies critical issues like reentrancy attacks, integer overflow/underflow, improper access controls, and unoptimized patterns—providing actionable findings with severity levels and remediation guidance. This skill works best as a pre-audit screening tool to catch issues before engaging professional auditors.

You can conduct comprehensive security audits of DeFi protocols by analyzing smart contract code for technical vulnerabilities (reentrancy, integer overflow, authorization flaws), simulating economic attacks (flash loan exploits, sandwich attacks, liquidation cascades), and identifying second-order composability risks that could lead to protocol failure. Claude acts as your interactive analysis partner, pattern-matching known vulnerabilities and helping you model attack scenarios before external audits or mainnet deployment.

You can conduct comprehensive security assessments of smart contracts by feeding Claude modular contract code with explicit vulnerability analysis frameworks. Claude traces execution paths, identifies state management issues, evaluates cryptographic implementations, and spots economic model exploits. This structured approach catches interdependencies and subtle design flaws that surface-level reviews miss, making it ideal for pre-deployment audits and incident investigations.
