Expenses for your rental activities still have to all be on Schedule E, not C. An LLC doesn't make a difference in your federal taxes or what you can deduct.
What you want to do is technically possible, but there are several hurdles. To deduct the vehicle using section 179, it would need to be a qualified SUV/pickup/van over 6000 pounds. The more challenging stipulation is you would need to use it more than 50% of the time for business use (and you need to log the miles to document that).
Ok, if it's still sounding do-able, the next issue is that section 179 can't be used to create a business loss, so it would only reduce your taxes for the year if your rentals are operating as a taxable gain (but rentals are often at a tax loss thanks to depreciation).
And then the last hurdle is that driving miles between your home and your rental properties by default is considered to be like your "commute" to work, and your commute doesn't count as business miles. You can get around that issue if you have a dedicated home office space that is used for the operation of your rental business. This applies regardless of the type of deduction you choose to take for the vehicle.
If section 179 doesn't work in your situation, there is bonus depreciation, which allows for a deduction of up to about $20k of the value of the vehicle for 2024. That still has the 50% use requirement, but can be used to create a tax loss. But then we have to get into talking about the passive loss rules, which may prevent you from actually being able to claim a tax loss if the deduction is more than your rental or other passive income.
Or you can claim the actual expenses (gas, insurance, etc) for the vehicle and regular depreciation, proportioned by the percent of business use of the vehicle. And then finally, there is always the option to just claim the regular standard mileage deduction rate of $0.67/mile. That's the easiest option.
But keep in mind all these options still require logging your driving trips, and having a home office if you're claiming trips from home to the rentals. And the passive loss rules may prevent you from getting a tax benefit if your rental deductions are more than your rental income for all of these options.
