If you're buying or refinancing an investment property, these are the two most common options. The right choice usually depends on how you qualify: based on your personal income or based on the property's rental income. For a full breakdown of all investment property loan options, read our guide.
How Each Works
Conventional: Focuses on you. Reviews personal income, employment, tax returns, DTI, credit, reserves. Your ability to pay matters most.
DSCR: Focuses on the property. Measures whether monthly rent covers the payment (DSCR = monthly rent / monthly payment). At $3,000 rent and $2,400 payment = 1.25x DSCR. Most lenders want 1.0x to 1.25x. Personal tax returns matter less. Learn more about how DSCR loans work and how to hit the DSCR ratio if your property is borderline.
Quick Comparison
| Feature | Conventional | DSCR |
|---|---|---|
| Primary qualification | Your personal income | Property rental income |
| Income documentation | Full docs (tax returns, W-2s, etc.) | Often minimal or optional |
| Interest rate | Usually lower (6.5-7.5%) | Usually higher (7.0-8.5%) |
| Down payment | Typically 15-25% | Typically 20-25% |
| Property count limit | Often capped at 4-10 financed rentals | Higher portfolio flexibility |
| Self-employed borrowers | Can be challenging | Usually much easier |
| Closing speed | 30-45 days (standard) | Often 14-30 days (faster) |
When Conventional Makes Sense
Conventional is the best fit if you have straightforward income and want the lowest-cost financing.

Choose it if:
- Strong W-2 or easily-verified self-employed income
- Comfortable debt-to-income ratio after the new payment
- First or second investment property -- portfolio limits haven't kicked in
- You want the lowest interest rate -- conventional is usually cheaper when you qualify
- The property may not have high rental income yet
For investors with clean tax returns and good DTI, conventional delivers the best value.
When DSCR Makes Sense
DSCR works best when the property is strong but your personal finances don't fit conventional boxes.
Choose it if:
- You're self-employed and take significant deductions -- tax returns understate actual cash flow
- DTI is too high -- multiple financed properties or other debts reduce conventional capacity
- You already own several financed properties -- conventional lenders have portfolio limits
- You want minimal personal documentation
- The property has strong, verifiable rental income
- You're building a portfolio rapidly -- DSCR allows more property count flexibility
DSCR is popular with experienced investors because it lets them keep buying even as portfolio size and tax complexity grow. Read our DSCR investor playbook for scaling strategies, and be aware that many DSCR loans include prepayment penalties.
Real-World Examples
Scenario A: First-time investor, strong W-2 income
$80,000 salary, clean tax returns. Property rents $2,500/month, payment $2,000/month.
Best choice: Conventional -- qualify easily, save 75 basis points vs. DSCR.
Scenario B: Self-employed investor, 5th property
Tax returns show $45,000 after deductions (actual cash flow much higher). Conventional hits portfolio limits. Target property: $3,500/month rent, $3,000/month payment (1.17x DSCR).
Best choice: DSCR -- conventional says no, DSCR approves based on property cash flow.

Smart Strategy
Use conventional early (cheaper money while you qualify easily), then DSCR later (portfolio growth flexibility as complexity increases). Working with a broker vs a bank matters here -- brokers typically have access to more DSCR programs.
What Matters Most
Figure out your own situation first:
- How many financed properties do you currently own?
- What's your realistic debt-to-income ratio?
- Do your tax returns fairly represent your cash flow?
- How fast do you want to grow?
If conventional works and rates are meaningfully lower, it's usually the better path. If conventional hits a wall due to portfolio size or income documentation, DSCR opens the door to continued growth.
