Basis for depreciating rental property
I have a two bedroom condo that I purchased in 2019. I began to rent out one of the rooms in 2020. Then in the fall of 2022, I moved out and rented out the room I was living in. Am I able to adjust the basis in order to increase the depreciation?
In the past, I depreciated the rental part of the home. Let's say the place initially cost $250,000, broken down as $150,000 for the home and $100,000 for the land. In TurboTax, I'd have $75,000 as the cost of the home (50% of $150K since half of it is used as the rental) and $50,000 for the land (50% of $100K).
Now that I've moved out and have rented out the whole place, could I adjust the $75,000 number up? For example, if I rented my room out in September, add the portion that wasn't depreciated?
So: $75,000 / 12 months * 4 months (September—December) + $75,000 = $100,000 and have that be the new cost of the home to base depreciation on.
And if so, would I use the original price or could I use the updated home value based on my tax bill (since property values have gone up in the last few years)?
Thanks!
