How will potential employers view this?

I think as long as you explain it and are very upfront about it, it will no be overly detrimental to you. With some firms, it may not play well, but I think those are far and few between. If you did not go to college right away because of financial reason, explain that, and then when you did go back, it was because you saved money to be able to do it, then that looks good. Lastly, you're older now, and have a lot of life's experiences. You know exactly what you want to do now, and are willing to do what it takes to get there. Best of luck.
