Core Rules

1. Zestimate is an Estimate, Not a Price

• ALWAYS caveat Zestimates: "Zillow's estimate, typically 5-15% off in this market"
• Check Zestimate accuracy for the specific ZIP — varies wildly by location
• Never use Zestimate as sole pricing guidance
• For sellers: compare to actual SOLD prices, not Zestimates
• For investors: Zestimate rents are even less reliable than home values

2. Calculate True Monthly Costs

For buyers, always include ALL components:

Component	Notes
Principal + Interest	Based on current rates
Property taxes	Pull actual, not Zillow estimate
Homeowners insurance	Varies by region/flood zone
PMI	If down payment < 20%
HOA fees	Check for special assessments
Mello-Roos/special districts	California especially

3. Market Context is Hyperlocal

• National trends are meaningless — real estate is ZIP-code specific
• "Days on Market" benchmarks differ: 10 DOM is slow in Phoenix, fast in NYC
• Always specify property type (SFH vs condo vs townhouse) — different markets
• Seasonal patterns vary by region: Phoenix summer ≠ Chicago summer

4. Investment Metrics Must Be Conservative

For rental property analysis, see investing.md. Key traps:

• Use 50% expense rule as MINIMUM, not ceiling
• Cap rate uses purchase price, not list price
• Factor vacancy (5-15% depending on market)
• Zestimate rent is often wrong — verify with actual rental comps

5. Zillow Data Lags

• Listings may be 1-2 days behind MLS
• Status (active/pending/sold) can be stale
• Zestimate updates monthly, not daily
• Always note data recency when citing stats

6. Role-Specific Guidance

User Type	Key Concerns
First-time buyer	FHA programs, true monthly cost, avoid overbidding
Investor	Cap rate, cash-on-cash return, expense reality
Seller	Competitive pricing, overpricing trap, market timing
Agent	Premier Agent leads, CMA comps, listing optimization

Zillow Traps

For All Users

• Zestimate ≠ market value (can be 20%+ off in unusual properties)
• Listing price ≠ sale price (especially in hot/cold markets)
• "Views" and "saves" include nosy neighbors, not just buyers
• Square footage and bed count often wrong — verify with county records

For Buyers

• Contingent/pending listings may show as available
• Don't waive inspection to "be competitive" — especially first-timers
• Pre-approval ≠ pre-qualification (huge difference for offers)
• Earnest money timing catches people off guard

For Investors

• High cap rate often means high risk (war zones, declining areas)
• Zestimate rent wildly inaccurate in many markets
• Property taxes can change dramatically after purchase
• Don't calculate returns on list price — use realistic acquisition cost

For Sellers

• Overpricing → stale listing → sells for LESS than fair price
• Price reductions signal desperation to buyers
• "For Sale By Owner" on Zillow gets less visibility than MLS
• Zillow doesn't know your renovations or deferred maintenance

Data Sources to Cross-Reference
