....I'm not, where have I said that the goal of this model was to COMPARE the return of home ownership verse renting + investment?
You don't seem to understand the whole point of this model. Yes, I may be bearish on the whole real estate market at this time, but the model was designed to view the whole thing from an unbiased, quantative perspective.
As above again, not designed for direct comparsion!
Just treat the model as, how much money invested, how much money in return! As simple as that.
Maybe it's the biases in you that is preventing you from making a sense out of this model. And like I said, the aim of this model is NOT renting vs ownership!!!!!
This discussion is almost worth another different thread. I am not going to bother talking about how much growth renting will increase along with whatever over the long term. 3.5% inflation was a guessmate, if you think rent will increase 10% over the next 30 years, that is 6% above wage growth (assumption on 4% growth), then so be it, add it into the model.
But do you really think this is sustainable in the real term?
Remember that the model is never an accurate representation of the real world. Just look at the intellectual nerds in rating firms designing Einstein's style computer model to price/predict mortgage backed bonds. The subprime event was something they called a 7 standard deviation event, or something that should not happen in their model every billion year or so.
This model I have cannot account for black swan events such as the subprime event. Imagine what will happen to your "return" if interest rate suddenly goes up to 15% in less than one year. It happened before, why it shouldn't happen again?
1, you your self said that you have shown this model to people to point out that they will not benefit much from owning their own home,... using this model for that purpose would not give a fair result,..... It says that they are only ahead by about 1% when the true figure is closer to 10% If that is not the point of the model then give me an example of a situtation where this model could be used, I can't see a reason for such a model that includes living costs such as insurance and rent.
2, what is the point of the model then,...
3, yes rent on a certain size and style of property can sustainablly increase faser tha wages,... look back at the example I gave, it's simple what is considered an average home today is likly to be considered above average in the future,....
meaning a average home getting average rent today,.... will be larger than the average homes being built in the future,.... there fore even if the average rent only increases with inflation, because this home is know bigger and on more land than the 2 bed aparments being built which are the new average then the house which once was average will be collecting a rent alot higher than the new average.
