Hey Tex, (BE CAREFUL, PEOPLE GO MISSING or END UP DEAD same as Mexico I guess) I've been to Phuket a fair few times (10 or something + 2 to Essan/Rural Thailand) and now reside permanently in Chanthaburi Thailand - Perhaps a little off topic but if you don't like tourists it might be better to rethink your relocation/holiday program area, tweek it just a little bit although the further you get from these areas the Thai people do not speak English language as fluently or at all sometimes. I positively hate tourists, find them offensive, rude, arrogant, ignorant (the list continues) as well as generally smelly. It seems like you're a bit of a loner, comments like 'off the grid' and 'not liking tourists' & such. I cannot give you any positive information regarding accommodation there as it will be bloody expensive (like everything there) however, in any out of the tourism 'normal' areas here, there are better quality cost effective alien opportunities - Thai people aren't stupid and do well in the opportunism side of things. So getting yourself onto an island run by the Thai mafia where they can take full advantage is a place I do not wish to go, or partake in their bulls!t so lesson learned. In the 'normal' areas of Thailand you can rent out apartments reasonably. I repeat that doesn't involve the likes of Phuket or Pattaya where it's highway robbery but if you absolutely must have the seaside view maybe try Hua Hin or Jomtien, have a good look around and don't be dragged into the full blown tourism area sides of things if you don't really want to be part of it. Multi story Shop/Apartments here go for about 3,800B + services per month unfurnished with Air-Con. I was told something by a bloke and it was in hindsight completely true "it's a trap" referring to Phuket. Bar ridden sleez pit, but if you like drugs, sex and rock'n roll, and have deep pockets this may well be the place you're chasing. Your well feed Golden Lab may have differing ideas (dropping it's weight in the heat)? My Husky was born and breed here, she looks great and is very happy. Also budget for a motorbike 16,000B - 60,000B+ purchase or 200B/day rental (again sliding scale), they are a must to have any sort of real freedom. Have a bit more of a think on local, I'd also have a look at Cambodia - not putting you off Thailand but I go there every 4 months and love it equally. What to bring depends on how long you're coming for, personal nick nacks and stuff you'd use every day + good thongs my preference is Oakley for quality in size 14 (difficult), pharmaceuticals can be difficult to acquire; they changed the laws on some stuff - what else would you be needing? Have a look at the visa requirements as it's the one thing that all foreigners here have difficulty with - Immigration officers are one of my pet hates. More info required
Best of luck and a bit more homework however I hope you really enjoy yourself.
