The cost basis includes:Purchase Price: The amount you paid for the property.Renovation Costs: Add the cost of improvements and remodels that significantly enhance the property's value.Closing Costs: Certain closing costs related to acquiring the property (like title fees) can be added to the basis.You will then allocate the total cost basis between the land (which isn't depreciable) and the building (which is depreciable over 27.5 years for residential properties).If you're unsure about how to allocate between land and building, you can use the allocation percentage from your property tax records or get an appraisal.This post does not create a CPA-Client relationship.
