Keep that up till about 25k gold then find a companion with good trade stats and have them create an enhanced caravan. That money should roll your party unti clan tier 3. When you get more flush, start buying up tje most expensive javelins in town. Get to 50 smithing and choose the "learn more from smelting" perk and then smelt the javelins.
Arenas in Mount and Blade 2 Bannerlord give you great opportunity to practice combat and win some gold. In each fight you get a random weapon - this solution allows you to test different weapons. The more opponents you defeat, the more gold you will get (from a few to a few dozen gold coins). Before you can start a kingdom in Bannerlord, get your clan to tier 2. Choose a well-located fief. (A castle is best) Ally yourself with a kingdom that fights your current faction. Example: Assuming you are part of Battania. If they go to war with the empire, you join the empire.Even having 5 mules in the early game will allow you to perform larger trades, collect more items from looters and bandits, and ultimately make more money. Each mule expands your carry capacity by 100, which is massive in comparison to the paltry 20 you get from a single horse (which is the same amount you get from troops).
The easiest way to earn money fast in the early game is to go fight in the tournaments, and gamble on you winning. Tournaments are great for three reasosns. First; tournaments are easy to win (except for swadia and their damn jousts -_-). Second, by gambling you can end up earning over 10,000 gold in every tournament.Mount & Blade II: Bannerlord.
