Run the Numbers Before You Structure the Deal
Most lease option deals lose money because investors skip the lease option calculator. The math looks simple — collect an option fee, charge above-market rent, pocket the spread. But miss one expense category and a "profitable" deal becomes a 2-year cash drain.
The 3 hidden costs that kill lease option profits:
- Maintenance burden. You cover the roof, HVAC, and structural repairs — averaging 1–2% of property value per year. That's $3,000–$6,000/year on a $300,000 property.
- Vacancy risk at turnover. If the tenant-buyer doesn't exercise, expect 2–3 months vacancy. That's $4,000–$9,000 in lost rent plus turnover costs.
- Legal costs. Poorly drafted agreements cost $2,000–$5,000 in attorney fees to fix.

Lease Option Math — A Real Example
Property: 3-bed single-family home, Atlanta GA, $275,000 market value.
| Component | Amount | Notes |
|---|---|---|
| Option fee (3%) | +$8,250 | Non-refundable, collected upfront |
| Monthly rent premium | +$200/mo | Market rent $1,800, charged $2,000 |
| Rent credit (25% of premium) | -$50/mo | Credited toward purchase if exercised |
| Net monthly spread | +$150/mo | $200 premium − $50 credit |
| Annual net spread | +$1,800/yr | Over 24-month option period |
| Backend profit (10% appreciation) | +$27,500 | If value rises to $302,500 |
| Maintenance reserve | -$4,125/yr | 1.5% of property value |
| Total profit (option exercised) | $35,450 | Over 24 months |
| Total profit (option not exercised) | $12,250 | Option fee + spread, minus maintenance |
Even if the tenant-buyer walks away, you keep the option fee and monthly spreads. That's the power of lease options — downside protection through upfront option consideration.
→ Compare this to subject-to deals and seller financing to find the right strategy for each property.
"I was about to structure a lease option on a property that looked like $15K profit. PIE's analysis showed the maintenance reserve and vacancy risk ate $8K of that. I renegotiated the option fee from 2% to 5% and the deal went from marginal to excellent."
