Example session with this skill installed
Analyze this rental property: $350k price, $2.1k rent, 20% down at 6.5% interest. Estimate 10% for expenses and $3k closing costs. Is this a good cash-flow deal?
- Read your context and instructions
- Compiled the real estate deal
I have analyzed the property based on your $350,000 purchase price and financing assumptions. The deal currently shows positive net cash flow, but the thin margins are highly sensitive to your estimated expense ratio and maintenance reserves.
Property Deal Analysis
1. Decision Snapshot
The deal is plausible with a 7.2% Gross Yield, but the 10% expense assumption is likely under-budgeted for a long-term hold. While cash-flow positive at $258/month, the margin for error is slim once CapEx and vacancy are fully modeled.
2. Inputs & Assumptions
| Item | Value | Status |
|---|---|---|
| Purchase Price | $350,000 | Verified |
| Closing Costs | $3,000 | Supported |
| Down Payment | $70,000 (20%) | Verified |
| Interest Rate | 6.5% | Supported |
| Monthly Rent | $2,100 | Supported |
| Operating Expenses | $210 (10%) | Hypothesis |
3. Analysis
| Dimension | Score | Evidence | Why It Matters |
|---|---|---|---|
| Gross Yield | 4/5 | $25.2k annual / $350k price | Strong top-line revenue potential. |
| NOI | 2/5 | 10% expense ratio is optimistic | Low scores reflect risk of understated costs. |
| Cash-on-Cash | 3/5 | ~4.2% return on $73k invested | Meets basic hurdle but trails index funds. |
| Break-Even | 4/5 | 82% occupancy required | Property can handle ~2 months vacancy per year. |
4. Key Risks / Gaps
- Underestimated Expenses: 10% rarely covers taxes, insurance, and management.
- CapEx Reserves: No explicit budget for major systems (roof, HVAC).
- Appraisal Gap: Low closing cost estimate ($3k) suggests potential out-of-pocket surprise.
5. Recommended Next Move
Primary Action: Obtain actual property tax records and an insurance quote to replace the 10% expense hypothesis.
Supporting Actions:
- Verify local "Section 8" or market rent comps to confirm the $2,100 target.
- Request a 2-year maintenance history from the seller.
6. Validation Plan
| Question | Evidence Needed | Cheapest Test | Pass Signal |
|---|---|---|---|
| Are expenses < 25%? | Tax/Insurance bills | Call local agent | Total < $525/mo |
| Is rent sustainable? | 3 Recent Comps | Zillow/Rentometer | Avg > $2,000/mo |
Next steps
- Update the expense ledger with actual tax and insurance data.
- Run a sensitivity test at 7.5% interest to hedge against rate changes.
- Call a local property manager to get a realistic quote for professional oversight.

About this skill
The problem
Beginner real estate investors often struggle to model property economics accurately, leading to hidden costs and poor cash flow decisions. Relying on gut feeling or incomplete spreadsheets often results in expensive mistakes and missed risks.
What it does
- Models rental property economics including acquisition costs, financing, and operating expenses.
- Calculates core metrics like Net Operating Income (NOI), Cap Rate, and Cash-on-Cash Return.
- Performs downside sensitivity analysis to test how vacancy or maintenance spikes impact the deal.
- Generates an evidence ledger to separate verified facts from hypothesis-driven assumptions.
- Scores deals across eight dimensions to identify the highest impact uncertainties.
Why this beats prompting it yourself
Generic prompts often hallucinate market data or miss critical expenses like CapEx reserves and vacancy rates. This skill enforces a structured evaluation framework that requires evidence for every claim, ensuring you never mistake an assumption for a fact.
Use cases
- Evaluating a specific rental listing to see if it is cash-flow positive.
- Comparing two different properties to determine which has a better risk-adjusted return.
- Determining the break-even occupancy rate for a high-leverage financing scenario.
- Structuring a preliminary research plan to validate local rent estimates and maintenance costs.
Known limitations
Does not provide regulated legal, tax, or investment advice. Requires manual verification of local jurisdiction property taxes and financing terms.
