Start out in Stockholm, and get into the Iron Goods business. It's generally not a good idea to trade only high-value items but the cash that it generates will help you get into the game.
Buy and sell a bit (also buy skins from Ladoga and sell in Stockholm, etc..), then make a workshop or two and join the guild. If you can, get a convoy and send it on an expedition to sell more iron goods. Profit.
Choose three or four towns that you will concentrate on building up, but I suggest Stettin to be one of them, as its grain and beer prices are great.
I'm suprised you didn't mention Wine from Cologne. I've made boat loads of cash that way. I've also found that doing triangle trade between Reval, Lagoda, and Novgorod pays well.
patrician 3 is great but i could do with some advice wat is the best indristry to get started with ? any 1 know tel me plese thanks 🤔
What I do is start in Lubec and build five pitch works, 4 brick works and late 5 or 6 sawmills. This gives me ample resources to build houses, wells or whatever. I also stash all of the cloth, pitch and hemp in my warehouse then when I have enough, I build a Hulk, then progress from there. I also loan money and get a lot of boats from those who fail to payback their loans. A lot of these are wrecks but can be upgraded and repaired. I arm my ships pretty well to capture and ward off pirates. I eventually wind up with five or six hulks and cogs, and sometimes a dozen or more sanakas(however you spell that,) and crayers. Of course I do use a trainer. I use Game Cheater, which is one of the best on the market as a money trainer. I can start with 999999999 and it will add everytime I spend, so I never run out of money. For those of you who are having a hard time, try this trainer and I think it will open up a whole new world for you.
