"Run the numbers. On a $24K property, the difference between a 58% allocation to depreciable improvements and a 75% allocation is $4000. Over the class life of the property, the difference in your allowable depreciation is about $145 (rounded) per year.
In the 25% tax bracket, a 75% allocation only reduces your annual tax liability by $36 for the property in this example. At this rate, it will take you 27.5 years to save a total of $1000 on your taxes."
You're correct...this issue is not the difference between getting rich and going broke. However, this $1000 you mention is for one property. I own 2 more with this same problem and they are higher value properties, so there's another $3000 or $4000 in depreciation I would prefer to claim. Further, I intend to buy additional properties which (following the trend) may well be a little fat in the land valuation. I simply want to take full advantage of one of the best tax advantages of owning rental property.
"At best, you just break even in this scenario if you plan to eventually sell the property. In the end, your wallet won't be any fatter or thinner regardless of whether you took the 75% allocation to improvements or the 58% allocation."
Correct, but I do not currently have plans to sell it. And with that philosophy, why depreciate property at all if you're only going to pay it back someday? It just makes sense to defer every 2013 tax dollar you can even if you have to repay it 27.5 years from now (unless you anticipate a significant reduction in tax rates between now and then).
