We bought a lot more land at higher prices through the years, up to about 150k per rai but that was some years ago... and land is always in demand near our village at going rates, if it is desirable land... in case you were implying that is a dream price, it is not... it is going rate and there are always more buyers than sellers... yes, it has proven to be a great investment -- that does happen.
And the added bonus is that the family has been making a living farming it in the meantime...
