How to Track Mileage Between Multiple STR Properties
No credit card required
If you manage multiple STR properties, trips between them may be deductible business mileage, and the trips from home to the first property and back are a separate question: IRS Publication 527 treats travel between your home and a rental as commuting unless your home is your principal place of business. Under IRC §274(d) and Reg §1.274-5T, the rules for multi-property tracking are the same as single-property tracking, but you need a system that correctly attributes each trip to the right property and captures the full route when you visit more than one in a day.
The Legal Basis: Business-to-Business Travel
When you operate your STRs as a business, each property can be a business location. Under Rev Rul 99-7, travel between two business locations can be deductible. This means:
- Home → Property A: generally commuting, unless your home is your principal place of business
- Property A → Property B: may be deductible
- Property B → Supply Store: may be deductible
- Supply Store → Property A: may be deductible
- Property A → Home: generally commuting, unless your home is your principal place of business
The key point for multi-property hosts: once you're on a business trip, the legs between STR locations are treated differently from the legs to and from home. Decide with your CPA which of your trips qualify.
A host with three properties who makes a weekly circuit (home → Property 1 → Property 2 → Property 3 → home) covering 60 miles round trip logs 3,120 miles/year from that one routine alone. How much of that is deductible depends on how the first and last legs from home are treated, so log every leg and let your CPA decide.
How to Log Multi-Stop Property Trips
When you visit multiple STRs in one day, log each leg of the trip separately. Reg §1.274-5T requires a record for each distinct trip, and each property visit is a separate business purpose.
Example: Three-Property Day Trip
| Leg | Origin → Destination | Miles | Business Purpose |
|---|---|---|---|
| 1 | Home → Property A | 12 | Post-checkout inspection |
| 2 | Property A → Property B | 8 | Supply drop-off for arriving guests |
| 3 | Property B → Home Depot | 3 | Replacement light fixture for Property B |
| 4 | Home Depot → Property B | 3 | Install fixture while on-site |
| 5 | Property B → Home | 20 | Return from property management circuit |
Total: 46 miles logged for that single day's trip. Legs 2–4 run between business locations; legs 1 and 5 run between home and a rental, which Publication 527 generally treats as commuting unless your home is your principal place of business.

Property-Level Attribution: Why It Matters
For hosts with multiple properties, it's important to attribute each trip to a specific property. This matters for several reasons:
- Different owners or entities. If Properties A and B are owned by different LLCs, their expenses need to be tracked separately.
- Mixed STR/LTR use. If one property is a short-term rental and another is a long-term rental, they may file on different tax schedules (Schedule C vs. Schedule E) and vehicle expense treatment differs.
- Property sale basis tracking. When you sell a property, the adjusted basis calculation requires knowing which expenses were associated with that property.
- Audit clarity. A log that clearly shows which trips served which property is far more defensible than a general "rental property" entry.
Add a property identifier to each log entry: "Property A — 123 Main St" or use a nickname like "Cabin" and "Downtown Unit." If you use a mileage app, create separate trip categories for each property so you can filter and report by property at year-end.
When a Trip Serves Multiple Properties
Sometimes a supply run serves all your properties at once — you buy cleaning supplies for three units in one Costco trip. The mileage for that trip is still one business trip. For the expense allocation, divide the supplies by property, but the mileage itself is one business trip regardless of how many properties benefit from it.
Log it with a business purpose that reflects the multi-property nature: "Supply run for all three STR properties — cleaning supplies, toiletries, and paper goods."
If you're making a multi-property circuit and you stop for lunch, the meal doesn't make the trip personal. The trip remains a business trip. But if the primary purpose shifts from business to personal at some point (e.g., you end the circuit at a family member's house for a weekend visit), the return miles may not be deductible. When in doubt, document every stop and its purpose.

Frequently Asked Questions
Can I deduct mileage when driving between two STR properties?
It may be. Under Rev Rul 99-7, driving between two business locations can be deductible, so if both your STR properties are business locations, driving directly from one to the other for business may qualify — you don't need to return home between trips. The legs between home and a rental are different: IRS Publication 527 treats them as commuting unless your home is your principal place of business. Decide with your CPA which of your trips qualify.
How do I log mileage when I visit multiple STR properties in one trip?
Log each leg of the trip separately: origin to first property, first property to second property, and second property back home (or wherever you end). Each leg needs its own date, origin, destination, mileage, and business purpose entry. Legs between properties may be deductible; legs to and from home are subject to the commuting rule.
Do I need to keep separate mileage logs for each STR property?
Not necessarily, but it's strongly recommended. Keeping property-level mileage records helps you allocate costs correctly if your properties have different ownership structures, different Schedule E vs. Schedule C treatment, or if you ever sell one property and need to document expenses.
