💡 Why Numbers Matter
Here's the truth: most investors lose money on bad deals because they fell in love with the property instead of the numbers. They saw potential, got excited, and convinced themselves it would work.
Professional investors do the opposite. They start with the numbers. If the numbers don't work, they walk away—no matter how perfect the property seems.
Using "optimistic" numbers to make a deal work on paper. Always use conservative estimates. If a deal only works with best-case assumptions, it's not a deal—it's a gamble.
📊 The 5 Key Metrics for Coliving
You need to know these numbers for every deal. Our Deal Analyzer calculates all of them automatically, but understanding what they mean is crucial.
1. Gross Potential Income (GPI)
This is your maximum possible income if every room is rented every day of the year.
5-bedroom house × $750/room/month = $3,750/month
$3,750 × 12 months = $45,000 GPI annually
2. Effective Gross Income (EGI)
This is your realistic income after accounting for vacancy. Even the best coliving operators have some turnover.
| Vacancy Rate | When to Use | Why |
|---|---|---|
| 5% | Established property, high demand area | Strong demand, quick turnover |
| 10% | Most properties (default) | Conservative, accounts for turnover time |
| 15% | New property or softer market | Extra buffer for uncertainty |
$45,000 GPI × (1 - 0.10 vacancy) = $40,500 EGI annually
3. Net Operating Income (NOI)
This is your income after all operating expenses—but before the mortgage payment. It shows how much the property generates on its own.
Typical operating expenses for coliving run 35-45% of EGI. This includes utilities (since you pay them), property taxes, insurance, repairs, property management, and reserves.
Typical Expense Breakdown
| Expense Category | Monthly Estimate | Notes |
|---|---|---|
| Utilities (all) | $300-500 | Electric, gas, water, sewer, trash, internet |
| Property Taxes | Varies by location | Check county records |
| Insurance | $150-300 | Landlord policy with proper coverage |
| Repairs & Maintenance | 5-8% of rent | Higher for older homes |
| Property Management | 8-10% of rent | If using manager; $0 if self-managing |
| CapEx Reserve | 5% of rent | Roof, HVAC, appliances fund |
| Lawn/Snow | $100-200 | If not included in management |
$40,500 EGI - $16,200 expenses (40%) = $24,300 NOI annually
4. Cash-on-Cash Return (CoC)
This is the metric that matters most for investors. It tells you what percentage return you're getting on the actual cash you invested.
Cash-on-Cash Return Formula:
CoC = (Annual Cash Flow ÷ Total Cash Invested) × 100
Total Cash Invested:
- Down payment (20% of $200K): $40,000
- Closing costs: $6,000
- Renovation: $25,000
- Furnishing: $9,000
- Total: $80,000
Annual Cash Flow:
- NOI: $24,300
- Annual mortgage payments: $12,864 ($1,072/month)
- Cash Flow: $11,436
CoC Return: $11,436 ÷ $80,000 = 14.3%
Cash-on-Cash Benchmarks
Below 10%
Weak deal. Look for better opportunities.
10-15%
Acceptable. May work in high-appreciation markets.
15%+
Strong deal. This is what we target.
5. Debt Service Coverage Ratio (DSCR)
DSCR tells you how easily the property can cover its mortgage payments. Lenders use this to qualify you, and you should use it to assess risk.
DSCR Formula:
DSCR = NOI ÷ Annual Debt Service
NOI: $24,300 ÷ Annual Mortgage: $12,864 = DSCR of 1.89
This means the property generates 1.89× the income needed to cover the mortgage.
DSCR Benchmarks
| DSCR | Meaning | Lender View |
|---|---|---|
| Below 1.0 | Property loses money | Won't qualify for most loans |
| 1.0 - 1.2 | Barely covers mortgage | May qualify, but risky |
| 1.2 - 1.5 | Comfortable cushion | Most lenders happy |
| 1.5+ | Strong cash flow | Excellent qualification |
🧮 The Deal Analyzer Process
Here's the step-by-step process for analyzing any coliving deal:
Step 1: Gather Property Information
- Asking price
- Number of bedrooms (and which can be converted to rentable rooms)
- Square footage
- Year built and condition
- Current property taxes
Step 2: Research Market Rents
- Check PadSplit listings in the ZIP code
- Check Furnished Finder, Craigslist, Facebook Marketplace
- Use the lower end of the range for analysis
Search "rooms for rent [ZIP code]" and "furnished room [city]" to see what competitors charge. Look at what's actually renting, not just what's listed.
Step 3: Estimate All Costs
Acquisition Costs
- Down payment: 15-25% for investment property
- Closing costs: 2-4% of purchase price
- Inspection & appraisal: $500-1,000
Renovation Costs (if needed)
- Light refresh: $5,000-15,000 (paint, flooring, fixtures)
- Moderate renovation: $15,000-40,000 (add bathroom, kitchen update)
- Heavy renovation: $40,000+ (major systems, layout changes)
Furnishing Costs
- Per room: $1,500-3,000 (bed, dresser, desk, chair, lamp, bedding)
- Common areas: $2,000-5,000 (living room, kitchen items)
Step 4: Run the Numbers
Input everything into the Deal Analyzer and review the output:
- Is Cash-on-Cash above 15%? ✅ or ❌
- Is DSCR above 1.25? ✅ or ❌
- Is monthly cash flow positive by at least $500? ✅ or ❌
Step 5: Stress Test
What happens if things don't go perfectly?
- What if rents are 10% lower than expected?
- What if vacancy is 15% instead of 10%?
- What if renovation costs 20% more?
If the deal still works with worse assumptions, it's a solid deal. If it only works with perfect conditions, walk away.
📱 PadSplit vs. Self-Managed Analysis
The numbers look different depending on which platform approach you use.
Key Differences
- PadSplit takes ~12% of gross rent
- They handle tenant placement
- Weekly payment collection
- Lower vacancy (typically 5-8%)
- Less management time
Net income may be similar due to lower vacancy and management costs.
Key Differences
- No platform fees
- You handle tenant finding
- Monthly payment collection
- Higher vacancy risk (8-12%)
- More management time
Higher gross income but more work and risk.
Our Deal Analyzer lets you toggle between both approaches to see how the numbers compare.
🎯 Know Your "Walk Away" Numbers
Before you analyze any deal, know your minimum requirements:
Suggested Minimums for Coliving
Cash-on-Cash Return:
≥ 12%
DSCR:
≥ 1.25
Monthly Cash Flow:
≥ $400
Cash Flow per Room:
≥ $100
These are starting points. As you gain experience, you'll develop your own criteria based on your market and goals.
⚠️ Common Analysis Mistakes
