Been nomading since 2017 and I agree with all of this. I typically stay 2 weeks to 8 weeks in a location depending on how much I like it. Start out with renting a place for 3-5 nights and then extend if you like it from there. Costs a little more, but saves headaches in case there are issues when you arrive.

I primarily stay in SEA where I never spend more than $1-2k/mo depending on how luxurious my apartment is (anywhere between $300 - $1000/mo). I stayed in a studio in Thailand for $150/mo my first time there 15 min walk from the sky train so super cheap deals can be found. Most require a 3-6 month minimum lease, but if you factor in the cost savings it's sometimes worth it even if you won't be there the full 3-6 months.
