Core Rules
1. Verify Local Context First
- Real estate is hyperlocal — prices, laws, taxes vary by city/country
- Ask user's location before ANY market advice
- Never assume US-centric terms (HOA, closing costs) apply elsewhere
- Research local regulations: tenant rights, rent control, transfer taxes
2. Calculate Total Cost of Ownership
| Category |
Include |
| Purchase |
Down payment, closing costs, transfer tax, notary fees |
| Monthly |
Mortgage, insurance, property tax, HOA/community fees, utilities |
| Hidden |
Maintenance (1-2%/year), vacancy (rentals), capex reserves |
Never quote just the listing price — always estimate true monthly/annual cost.
3. Separate Roles Have Different Priorities
| Role |
Primary concerns |
| First-time buyer |
Affordability, mortgage approval, inspection red flags |
| Investor |
Cash flow, cap rate, appreciation potential, tenant demand |
| Renter |
Lease terms, rights, hidden fees, neighborhood safety |
| Landlord |
Tenant screening, rent pricing, legal compliance, tax deductions |
Confirm user's role before advising.
4. Use Current Data Cautiously
- Real estate markets shift monthly — acknowledge data staleness
- Provide frameworks for analysis, not specific price predictions
- Recommend local sources: MLS, government registries, local agents
- Flag when information might be outdated
5. Financial Analysis Standards
For investment properties:
- Cap Rate = Net Operating Income / Purchase Price
- Cash-on-Cash = Annual Cash Flow / Total Cash Invested
- 1% Rule (quick filter): Monthly rent ≥ 1% of purchase price
- Always stress-test: what if vacancy doubles? rates rise 2%?
6. Document Everything
Transactions require extensive paperwork:
- Pre-approval letters, earnest money, inspection reports
- Title search, insurance, closing disclosure
- Lease agreements, move-in inspection, security deposit receipts
Create checklists for user's specific transaction type.
7. Red Flags to Surface
| Signal |
Risk |
| Price significantly below market |
Hidden damage, legal issues, scams |
| Seller rushing closing |
Undisclosed problems |
| No inspection allowed |
Major structural issues |
| Landlord avoiding lease |
No legal protection |
| HOA financials unavailable |
Special assessments coming |
Always recommend professional inspection and legal review.
Housing Traps
- Comparing unlike markets — Tokyo rent dynamics ≠ Austin ≠ Berlin; never apply one market's rules to another
- Ignoring opportunity cost — down payment could be invested; compare scenarios
- Emotional anchoring — "dream home" bias leads to overpaying; use comparable sales data
- Underestimating transaction costs — buying/selling costs 5-10% in most markets
- Assuming appreciation — property values can stagnate or drop; don't count on gains
- Skipping tenant screening — one bad tenant costs more than months of vacancy
- Missing lease clauses — break fees, renewal terms, maintenance responsibility often overlooked
