If you want your short-term rental to perform like a business, you’ve got to treat it like one — starting with how you finance it. A loan isn’t just a means to an end. It can shape your monthly cash flow, tax write-offs, and growth strategy.
Here’s how to structure a loan that maximizes profit — with sample numbers to prove it.
1. Match the Loan to the Property’s Income Profile
Buying a 3-bed beach house with 80% occupancy? It can likely support a more aggressive loan structure than a downtown condo with sporadic bookings.
Pro Tip: Use AirDNA or actuals to calculate:
- Average monthly gross income
- Total monthly expenses (mortgage, taxes, insurance, utilities, mgmt)
- Net cash flow target
Aim for at least $500–$1,000/month net cash flow after all costs.
2. Know Your Loan Options
Here’s a sample breakdown for a $600K Airbnb in St. Augustine:
Option A: DSCR Loan
- 20% down ($120K)
- Rate: 7.5% (interest-only)
- Monthly Payment: $3,000
Option B: Conventional Loan
- 15% down ($90K)
- Rate: 6.75% (P&I)
- Monthly Payment: $3,200
Option C: HELOC-funded purchase
- 100% finance (from HELOC on another property)
- HELOC Interest: 8%
- Monthly Payment: $4,000
If the property nets $6,000/month, your cash flow looks like:
- DSCR: $3,000 net
- Conventional: $2,800 net
- HELOC: $2,000 net
Each loan serves different goals — max leverage vs. best rate vs. speed/flexibility.
3. Factor in Loan Costs & Prepayment Penalties
Don’t just focus on monthly payments. Ask:
- How many points to close?
- Is there a prepayment penalty if I sell or refi?
- Can I recast if I pay down principal?
4. Always Model with Startup Costs
Include:
- Furnishing ($10–$30K)
- Repairs & upgrades
- Closing costs
- First month utilities, subs, and team setup
