Seeking Advice on Collecting Outstanding Balances After Eviction

After a tenant has been evicted in Washington County, MD, and there is still an outstanding balance even after applying the tenant’s security deposit, are my only options for collection limited to small claims court and utilizing a collection agency? Are there any additional methods I may have overlooked? Additionally, what do you consider the most effective approach for collecting the owed amount? Any assistance, whether it's links, videos, or advice, would be much appreciated.
