The pricing of art varies and is all over the board. It is based on many factors including the material of the work such as size of the canvas, quality of paint, and other materials. The time a work takes to create must be taken into account. The artist who creates the work is as everyone knows, one of the main factors as that determines the demand and is arguably the most important factor.
My view is that you should always buy art you like. You should NOT buy solely on the advice of an advisor (who probably has an agenda other than your best interests) so you want art that you enjoy…the fact that it might increase in price over time is an added bonus! So buy what YOU will enjoy looking at everyday!
My work for example, has steadily increased in value as I have sold and become more known. This trend continues…you can be part of it. Acquire some of my works and you will not only have beautiful artwork to enjoy but you will know that the price you pay today is a bargain compared to what they will be sold for as time goes by.
