Side-by-Side Comparison — Rank Investment Properties on One Screen
Comparing deals in your head leads to bad choices. The side-by-side tool lines up cap rate, cash flow, cash-on-cash, and DSCR across properties so the best one is obvious.
The side-by-side comparison tool ends the guesswork. Enter two or more deals and it ranks them by the metrics that matter — cap rate, monthly cash flow, cash-on-cash return, and DSCR — on a single table.
Why Spreadsheets Fail Investors
Most deals are evaluated one at a time, in different tabs, on different days. Memory fills gaps, and the "best" deal wins by recency, not merit. A side-by-side view forces an apples-to-apples comparison at the same moment.
Metrics That Matter
| Metric | What it answers |
|---|---|
| Cap rate | Return ignoring financing |
| Cash-on-cash | Return on your cash |
| Monthly cash flow | Survives vacancies? |
| DSCR | Can it cover debt? |
No single metric decides. A high cap rate with negative cash flow (expensive loan) is different from a modest cap rate with strong cash flow.
Building the Comparison
Add each property with its price, rent, expenses, and loan. The tool computes the four metrics and highlights the best value per row. A "verdict" summarizes which deal leads and why.
Weighting by Strategy
- Cash-flow investor: rank by monthly cash flow first.
- Appreciation investor: rank by cap rate and growth market.
- Leverage-focused: rank by cash-on-cash.
- Commercial buyer: gate on DSCR ≥ 1.25.
Example Output
| Deal | Cap Rate | CoC | Mo. CF | DSCR |
|---|---|---|---|---|
| A — Dayton | 7.8% | 9.2% | +$310 | 1.6 |
| B — Columbus | 6.1% | 7.0% | +$140 | 1.4 |
| C — Coastal | 3.9% | 3.0% | −$210 | 0.9 |
Deal A wins on every return metric and clears DSCR; C fails the debt-coverage gate. The decision is now obvious.
From Comparison to Action
Send the winner to Saved Deals, then to full due diligence. Comparison narrows the field; diligence closes the deal.
Normalize Inputs Before You Compare
A side-by-side table is only honest if every deal uses the same assumptions. The most common way investors fool themselves is comparing an optimistic model of Deal A against a conservative model of Deal B. Before you rank anything, standardize the hidden inputs: use the same vacancy rate (unless the submarkets genuinely differ), the same management fee (even if you'll self-manage — your time has a cost), and the same reserve percentages for maintenance and capital expenses. Only then are you comparing the properties instead of comparing your own moods on two different days.
A Scoring Framework When No Deal Wins Everything
Real comparisons are rarely as clean as the example above, where one deal sweeps every metric. More often Deal A leads on cash flow while Deal B leads on cap rate and appreciation potential. A simple weighted score breaks the tie: assign each metric a weight that reflects your strategy (say cash flow 40%, cash-on-cash 30%, cap rate 20%, DSCR 10%), score each deal 1–5 per metric, multiply, and sum. The winner is the deal that best fits your goals — not the one that happens to top an arbitrary single column.
| Metric (weight) | Deal A | Deal B |
|---|---|---|
| Cash flow (40%) | 5 → 2.0 | 3 → 1.2 |
| Cash-on-cash (30%) | 4 → 1.2 | 4 → 1.2 |
| Cap rate (20%) | 3 → 0.6 | 5 → 1.0 |
| DSCR (10%) | 5 → 0.5 | 4 → 0.4 |
| Weighted total | 4.3 | 3.8 |
Red Flags a Comparison Reveals
- A high cap rate with negative cash flow usually means an expensive loan or a war-zone market — the yield is compensation for risk, not a bargain.
- DSCR below 1.0 on any deal means the property can't cover its own debt; it fails the lender's gate and yours.
- A deal that only wins on appreciation is a speculation, not an income property. Make sure at least one deal in your set can survive on cash flow alone.
Using the Tool Below
Add properties one by one; the table updates live. Adjust assumptions to stress-test (raise vacancy 2 points, drop rent 5%) and watch rankings shift.
