Presume that was in the UK. (also values rise in countries like NZ, Aussie, USA etc),
But sadly 99% of house prices in Thailand do not rise in value like that. Most of the time a person is lucky to sell for a small profit, as the older a house gets here, the more it deteriorates due to weather, humidity etc, and every few years they need a really good spruce up (which costs). But in some cases the land value will of course rise.
The other problem is that Thailand has valuations on land/houses for tax purposes, but no set valuations for buying/selling, meaning its really up to a seller and buyer to determine a price that's amenable to both.
Other posters will come along with their own experiences/stories, so they will be useful also.
