Credit scores are largely a product of time.
At a 500, it means you have lots of negative credit items, like late payments, collections etc, so you want to work on removing those first.

500 to an 800 will likely take at least 3 to 4 years, maybe longer.
How long does it take to build a 700 credit score?
It will take about six months of credit activity to establish enough history for a FICO credit score, which is used in 90% of lending decisions. FICO credit scores range from 300-850, and a score over 700 is considered a good credit score.
How long does it take to go from bad credit to good credit?
And a late payment stays on your credit report for seven years, though its impact to your credit score will recede over time. Because payment history is the most significant factor in both the FICO and VantageScore models, it can take up to two years for a score to rebound after getting back on track.
How long does it take to build a 600 credit score?
It will take you six months to accumulate enough history so a FICO score can be calculated. You should be able to get a VantageScore much more quickly. You will not be able to build a credit score approaching 850 in that time period, but you may be able to break 700.
