If I were in your position I wouldn't go out and buy those things, 3 year interest-free loan or not. It's still a debt that would have to be paid later. In particular, I'd skip the appliances, especially if you haven't yet confirmed where you will be renting for the first couple of years. Most
condo apartments come with a fridge freezer of some kind and many have a washing machine too. If not (or if the existing items are grotty), you can ask for new units as part of the negotiation. If you were to buy and bring your own appliances, but then find an (otherwise ideal) apartment that already has them, you may find the landlord reluctant to take them away - they'd have to store them somewhere, so the usual response is that
you have to store them in the maid's room or somewhere else. Hence unnecessary clutter.
Also, there's the wear and tear aspect - we bought a dishwasher a few years ago and it didn't take long before rust started appearing on some of the out-of-the-way areas. With the humidity here, everything deteriorates faster than it would in a temperate climate. You already mentioned about international warranties, but even if your overseas-purchased appliances are theoretically eligible for warranty service here, you may find the local service centres reluctant to fix them if they go wrong.
As regards furniture, I guess to some extent it depends on whether you are paying the removal fees - if so, you'd need to weigh up whether the additional costs for bringing new furniture were worth it. If you were to purchase expensive furniture, consider also the potential for damage in transit (hot sea container, etc.). Sure, you would (presumably) have insurance, but think of the hassle of claiming and getting repairs done after you've moved here. Plus the other issue already mentioned above - what happens if your 'perfect' apartment already has a dining room table, decent sofa, etc.?
If you need to buy furniture here, my advice would be to not go for expensive stuff (at least not at the beginning). Some people look down their noses at Ikea, but IMO they are a good source of reasonable furniture at reasonable cost that should last for a few years at least while you get established. Other good sources are classified ads (see above on this site - there are often interesting items there), or do a search for 'expat auctions'. In short, finding furniture here is not a problem and you can get stuff to meet most any budget.
When we moved here, although we had a 20ft container (could have had a 40ft one if we'd wanted it) and the removal costs were paid by my employer, we just brought our beds and a few other items of furniture that were 'special' to the kids, etc., and left the rest in the UK, either in our
property there (which we rented out), or given away to family and friends. My advice would be - if in doubt - leave it out; that will give you the widest set of options when you get here.
This is just my perspective of course; as you say, others may have differing views. Good luck with the move.
