What are some high yield dividend stocks to get, that will last for a long time?

If you don't want to DIY, I think you can consider the roboadvisor, Syfe's 100% REITs portfolio and get into dividend investing easily. The portfolio tracks the SGX’s iEdge S-REIT Leaders index which has 20 top S-REITs (to my knowledge). Dividends paid out quarterly.

SG banks & branded Reits(mapletree, capitaland) sounds like good pick for you.

MAS just realised circular asking bank to cap dividend to 60% of last year's.

Nothing is permanent, do constantly reflect whether those companies can keep survive well.
