Production building costs

Are you in a neighborhood.? If you are... maybe your hoodmates can sell you th8ngs forehead 5hat you can turn around and sell for top coin. BUT- if you do have hoodmates that will do this for you, make sure to ask if there is anything you can do for them as well 😉

Don't waste products on truck orders! Usually you will make more selling in your shop than to farm visitors, trucks or Boats.

In short..... keep all of your buildings going constantly... load them with long/expensive item over night and sell in the morning. The same for crops.... tomatoes, onions, tea, lettuce etc

If you can use ernest and rose a few times they can help with stocking. Use Tommy to buy things like diamond rings then sell for full price.

First of all, welcome lillypad12hopper to JHD.  IIRC, I was around level 50 when I started to plant, harvest, and sell soybeans nonstop until I became a HD millionaire.

I'd like to suggest you also make goods nonstop and sell more than you buy.

Every 1-2 weeks, various double coin events happen. My advice is that you should take as much use of them as you can:
- if it's a truck event, send as many trucks as you can but don't forget to count whether the order gives you more coins than selling the exact same items in the roadside shop. Also, don't forget to trash the orders you're not willing to complete (e.g. dairy products and sugar, it's better to use them for production)
- the most profitable one in my opinion is the Farm Visitor double coin event. The thing is, you buy the most expensive and the most common products and plants in the newspaper. Don't hesitate to spend coins, as you'll earn way more! For your level it could be woolly chaps, blackberry muffins, purple dresses, blackberries, cherries etc. Then you make sure they are top 1-2 items of your barn and silo (ore, jewelry and expansion materials don't count, so it's not necessary to exceed them). It's also better to have at least 1 of every item (as well except those I've listed), so that the visitors wouldn't want to buy them. When the visitor buys a part of your top items, go to the newspaper again and repeat the actions. When the event is about to end or you're logging out, don't forget to sell the excess in your roadside shop. This should give a lot of coins in revenue.

Due to costs of buildings, has anyone skipped some production buildings and come back much later to purchase?

I am level 179 now but when I started out, I was planting soybeans over and over and collect eggs to sell. Soybeans sell fast and when I am not busy with other things, I check on HD about every 20 minutes so this works out well.
