For $700 a month, you can find a nice condominium with good amenities in a pleasant neighborhood. However, there are cheaper options available. We managed to secure a two-bedroom unit for $800, excluding utilities, so $700 seems reasonable. Keep in mind that you'll need to provide a two-month deposit along with the first month's rent.
Also, just a heads up: $2k-$3k in Thailand might not stretch as far as it used to. Everything's getting pricier, especially for foreigners. Luckily, you don't have school age kids, or you'd be totally broke. Lol.
During the first few weeks, it's advisable to avoid street food to prevent food poisoning, which could lead to a hospital visit so good health insurance is a plus. Enjoy your new place and good luck!
Visa rules can change frequently, so it's best to check the latest info from official sources. In Thailand, you can apply for an education visa if your child attends an international school. If you have a remote job, a Digital Nomad Visa (DTV) might be an option. Always verify the current requirements before applying
