Do It Yourself Landlords often pay more taxes than they have to because they miss out on important deductions.
Property Repair costs are deductible, but one must know the difference between "repairs" and "improvements" because the deductions are different.
Landlords can also deduct mileage to and from the property and can deduct all mortgage interest and interest on equipment/repair loans.
Using a property management company like Green River Property Management is a smart idea; the cost is deductible and they do all the above for you.
