If you can afford to pay for a house in full using cash, is it better to do that instead of taking a loan? Thanks?

I answered a similar question here https://seedly.sg/questions/what-would-be-a-bet...
For that, I also created a google sheet, to compare between taking a loan or paying using cash https://rplg.co/slopu

In short, If your loan interest is 2.6%, and you are able to get investments at least 2.8%, technically you will come ahead by taking a loan and using the money to invest.

You can make a copy of the google sheet and do your own calculations https://rplg.co/slopu

But after that, it's really down to your personality and objectives. Some people might find active management of the investments a hassle. Some people feel they can't even do 2.8%, and they feel that they might have a double whammy if banks want their loan back, and their investments are illiquid.
There are other intangible factors such as having liquidity just in case or seeing what is your age and all that...

There's no perfect answer, but if it was me, it would be the loan any day, every day.

Yes. That is the smarter way. (mortgage loan current rate is 1.89%)

A mortgage loan is a secured loan and hence enjoys very low returns. now the banks are fighting to offer 1.89% for first year of interest rate, and even as it increase in 2nd and 3rd year, it is still only below 2.3%

Taking the cash on hand to invest in something can easily net you more than 2.3% pa, even if you choose safer and lower returns instruments.

I personally will suggest IWDA ETF for global investing, or STI ETF for Singapore scene. If you are risk adverse, then go for those income funds, or bond funds. It is really not difficult to seek returns higher than 2.3% currently

For me, I would definitely take the loan due to low interest rates and invest the rest in equity!

If you have the following in place,

1. 3-6 months emergency fund
2. Fully funded retirement
3. Fully funded kids education

...then yes, throw everything into the house. Also, if this is a windfall, IMHO, you should clear the stuff above mentioned (including the house) before you "invest" the remainder.
