Yahoo Finance has an article talking about whether you should buy a home and include this Table.
I wonder where in the world journalists get their data. I've lived in 10 houses over the past 30 years - all of them over 90 years old. The kind of homes that you think would need major renovations (and many have). I've kept pretty good records of what I have spent and I find this data really flawed. The most expensive rehab we did was a total gut (only the original walls remained) and it cost us $60k. Over the past 30 years I have spent less than $100k on maintenance as well as major improvements. In every case that I have made improvements, the homes' value has increased by more than 100% of my cost.
Most people that own a home do most of the repair work themselves and often take on large projects as well. Is this journalist assuming that people are spending $300k to remodel their 1990's home? I suppose a few people are foolish enough to over improve a home, but I suspect that is a minority. Is he a total incompetent that he can't change a light bulb without calling an electrician or so lazy that he hires out maid service and lawn mowing. Part of home ownership is having a do-it-yourself attitude.
When journalist present flawed data, their whole story line is questionable. And today journalism has extremely low credibility with any story that deals with data (especially science).
