Macookie:
I believe your bias is showing through.
If we are talking about a say 700K home as more or less average for a single detached in a reasonable neighbourhood; 3% is $21000/year.
My experience: I am in a home worth somewhat more than the $700K. I have been in it for 25 years.
Costs:
Roof I did at 18 years: Cost $6000
Windows I did at 20 years (2/3) One side of the house with less sun gets better duration and also internal wainscotting could not be matched so some not replaced. Cost $9000 (Approximately $1000/window opening on average).
Doors for cosmetic reasons $4000.
Painting every 3 years outside trim: Inside about every 5 years: cost: $4000
Carpeting replaced fully at 20 years: $10,000.
Flooring (upgraded not necessary) $20,000.
New Kitchen (at 22 years cosmetically) Total redo $65000(note no rental will do this except a very high end).
New Deck: (done in stone at 2 years; still good... ) cost was $25000
Driveway: interlock...done once: cost $10000. Spraying and maintaining...perhaps $1000 every 3 years.
Eavestroughs...no need to replace.
Landscaping: $1000/year...this is generous though we had $10K for the initial planting, flower beds etc.
The point: $200,000 total. Let's assume another $50,000 miscellaneous for a total of $250,000 Some of this is capital improvement and adds value to the home but still. This works out to $12000/year based on a 700K home is.
Still; over 25 years that I have been in my home.... this is 1.7% and in fact my home is worth more than 700K.
Perhaps for a $500K home this would be closer to the 3% mark but I suspect that also one would not be spending the additional dollars that a larger more expensive home such as mine would command so I concur 3% is high.
That said, it is important to maintain houses or they deteriorate. Also, condos can be more expensive and sometimes one has to do repairs when one is not financially equipped to do it....in other words, you do not get to choose the timing.
Yes, renting makes more sense than owning at present prices. On that we agree. However, as MadMax pointed out, money in real estate is money not available to invest with "financial planners" or the investment industry.
