Sure. And I know a property with an excellent REAL APPRECIATION RATE (calculated by looking at appreciation rate of 50% between 1995 and 2006). Would you like to purchase it?
Scott, I don't mean to be harsh, but your post is hogwash. Your method might be okay to estimate fixed expenses, but 1) those expenses will need to be multiplied by some factor to project future expenses, in which case the accuracy is at the mercy of your factor, and 2) this ignores all variable costs (or, even worse, you assume that past variable costs are a good estimate for future variable costs... if so, I hope that sounds a little off when you actually hear it out loud).
As far as I can tell, the main beef people here have with the 50% number is that it seems too easy. Repeat after me:
There is no way to deterministically predict future costs.
All you can do is estimate, and just because your estimation method is more complicated sure doesn't mean it's more accurate. I have pointed out a couple times that the 50% number is mathematically flawed. There is no discernible dependency between gross rents (set by market) and expenses. However, there are a lot of models in economics (and statistics in general) that work even though one can't quite tease out the logic behind the numbers. (In fact, if you want to get technical, the entire scientific community is built upon these situations, with very few exceptions. But I digress...)
