Ah, yes! I bought ACNH and it's honestly what's kept me from going crazy so far.

Tips:

1. Be careful buying paintings from Redd-- sometimes they're fake! If you ask to examine the painting first, you can usually tell if it's fake. (Something will probably be misspelled or whatever.)

2. If you want until after 7 pm and get a Nook's Mile Ticket, you can sometimes get a scorpion/tarantula island. Scorpions and tarantulas sell for a lot, so if you're having trouble paying off your debt, I suggest going to one of these islands and catching a few. 

I have ACNH and I'm loving it. Here are my tips.

1. Bell vouchers are the way to go. I'm not sure when they are available but if you use the NookStop and redeem 500 for a bell voucher, you can then sell the voucher for 3,000 bells. 

2. Catching tarantulas and scorpions are really hard(I'm never caught any.) but if one of them sees you, freeze. Then try and sneak up on them with your net by holding down A. If it turns back to look at you, freeze again but don't let go of the A button. Otherwise your net will smack down at your feet and it'll attack. Again, I'm not an expert on these guys at all so other tips on them are appreciated. 

3. Fossils! Dig up fossils and have Blathers assess them. If they are not new fossils, sell them for a lot of bells! 

4. Bridges and inclines are great, but they are expensive. If you want to get them finished sooner, try setting a mininum of bells that you want to pay everyday. 

5. Celeste! On clear nights after 7pm, you'll meet Celeste, an owl who is Blather's sister wandering around the island. She will give you DIY reciepes involving star fragments. On some nights (usually Isabelle will tell you in the forecast), there will be tons of shooting stars. Look up at the sky with the R stick and press A when you see a shooting star cross the sky. The next day you will find star fragments on the beach. Use them for DIYs or sell them for a good sum of bells. 

6. Give gifts to your residents! You usually have to talk to them a lot if they're new but there will an option. If you give them gifts that they really like, they'll give a gift back or some bells. Try and pick gifts that match their personality.

7. When Nook Miles + tells you to catch fish or bugs it can be easy to just let them go if they are not new or cool. Instead sell them, its not a ton but it's better than nothing!

8. You can redeem miles for bigger pockets which is super vital. It's a lot of miles but so worth it. 

9. The drop-off box! If you're not saving up for a specific item that day at Nook's Cranny and probably aren't gonna to spend any money for the rest of the day, sell items through the drop-off box. Turnips can't be sold and hot items will not be worth twice however. The money from the drop-off box goes to your savings the next day. I find it helps me focus on my loan more because I don't directly recieve that money and I usually pay from my savings.

10. Turnips! On Sunday before noon, you can buy turnips from Daisy Mae. They are sold in packs of 10 but are not super expensive. Throughout the week try to sell them at Nook's Cranny for more than you bought them. Ask them for the turnip prices. Note: you can't sell turnips on Sundays and after a week of having them, they go rotten and are worth nothing. 

Oh boy, that was a lot of tips. Hopefully some of them were helpful.  

I don't play (Because ACNH and Switch are WAY to pricey..) but I saw a video that said if you collect a bunch of weeds you can get good money for it

This was me. I'm cringing at my attempt to use texting slang on the CB- also, auto correct thought i said leeks instead of let's lol
