How long do I need to leave Thailand after cancelling a work permit before I can return?

I think you're a bit mixed up 😮 A work permit doesn't let you stay in thailand it lets you WORK here.

If you're on the initial 90 day entry of a Non-B visa you can stay until that 90 days runs out

Whereas if you're on an extension of stay based on employment (look at the stamp in your passport) you need to cancel the work permit, take that receipt and the termination paperwork to the immigration office that issued the extension, cancel it, then leave.

Most people cancel their extensions about a week or so before the termination date on their paperwork <- because immigrations cancels it effective the termination date and that lets you have time to coordinate getting out of the country

up to your case. too many exempt or visa run?

Following is for some who need to get TR visa.

don't do van or visa run. reckless driving, shit hotels and plus you can handle proces yourself, unless you have already got a warning by immigration.

As for getting tourist visa, pick Vientiane or Penang, up to your budget. plan ahead for scanned passport, photos, cash for "show money" etc for the process, including in and out(coming back to Thailand).

apply in Loas or Malaysia in evisa website, after you have stamped in your passport.

Have valid bookings for flight into Bangkok and hotel(not sure if showing house rental will make things easier or more difficult)

process will take 14 days at most, but usually it's 3 to 4 days.

then when coming back, be sure to have onward flight travel(either to your country or places like Vietnam. you can find cancellable ones. I will leave just at that).

5 minutes

Van run

3 seconds

You have to leave within 24 hours but can come right back after you get a new Visa

Just cross border and come back

There is no set time, just make sure you cancelled your extension too (if you had one)
