After collecting fine art for a few years, i've learned a thing or two about fine art. The biggest lesson I've learned is the average persons misconception of what "fine art" exactly is. Most people assume that fine art is unattainable and is only for the rich. They believe that only artists like Warhol, Monet, Jeff Koons or Banksy work is considered fine art, because of the high prices their work is fetching at auction houses.
This is wrong. Fine art is artwork made by an established artists in the art market. Whether they're represented by a gallery, agency, auction house or sometimes self representation. An easy way to determine whether an artists work could be classified as "fine art" is to simply look into the artists resume. Go to their website or Artsy bio and read about them . Here's 5 affordable artists, I recommend to look into.

Research, research, research ... I cannot stress this enough. You aren't going to find the next Andy Warhol or Roy Lichtenstein just browsing around randomly. If you find an artist you and you like his work, but you also want to see the potential value of his artwork in the future .. get in the habit of researching said artist. What are you supposed to research you may ask?
You need to find out everything about this artist, where he/she's from, how long they've been an artist, where have they shown their work .. whats the current average value of their work. Have they had a solo show? Are collectors purchasing their work? When the artist releases new work, does it tend to go higher when being resold?
These are all questions that need to be answered when you're purchasing fine art and looking to make some a return on your purchase in the future.

I've always found myself voicing this opinion to friends when they get a new place, a home isn't completed without art or something on the walls. Unfortunately .. don't think fine artwork is attainable and they tend to hangup random artwork from IKEA or a garage sale, or some other large department store.
Sometimes this artwork is costing them the exact same price, if not more than the price of some fine art out there. Whether you're a fan of art or not, we all find ourselves purchasing art eventually when we've got our own space, so why not make it an appreciating asset as well? Art Is a Commodity after all.

A great place to find and purchase up and coming artists is 1Xrun, they've got a vast amount of artists who're either up and coming or established in the art market.
The biggest piece of advice I can share with you all is, don't purchase art with the sole intention of making money .. if the thought of making a return on your purchase is on your mind, that's fine. But make sure you enjoy the artwork you're purchasing, or else it won't sit right with you and you will have doubts on your purchase.
To my earlier point, many artist who check off some or all of these points I've mentioned, sell art for reasonable prices. Anywhere from $100 - $1000+ USD at a time, prices you'd pay for commercial made artwork. When instead, you can purchase a unique piece of artwork that has a good probability it will go for more in the future. What I'm trying to say to you is that there IS money to be made in the fine art market and you DON'T have to be rich.
This is NOT investing/financial advice, we're sharing our opinion respectfully from a speculative point of view.
