IMHO, iherng has not been a reliable source of property reviewer since he became popular. (though he likes to maintain he's not biased)
The money/sponsor is too attractive to say no.

The not so subtle promotion of his company - makeoverguy in his recent video is also putting me off.

I honestly don't think he is paid by property developers but I do agree he is intentionally skewing his views to be positive.

From a youtuber business point of view, if he is overly critical, two things will happen:

1. Developers will stop inviting him and he will lose some "early access" to certain developments and launches
2. He risks alienating a lot of his viewers. Imagine buying Lumi and thinking it's a good investment and piling your entire savings and future on that property; and then suddenly some property youtuber tells you it is shit. Whether it be true or not, the property owner won't be happy. Drives your property market value and rent down, etc.

That's just my take. Do not treat them as "reviews". They are more like walk-arounds and early impressions.

What annoys me is his recent NFT and cryptobro shit.

I really laughed at all the comments.

To be a wise buyer - be it for own stay or investment.  We should rent out first before buying.  We need to stay inside the unit for few months to know the real facts.  No point listening to others ( friends/agents/ developers or youtubers ( they always have bias comments).  Experienced it and decide ourselves with no regrets as there are many choices out there.

To rent a unit RM30k ( RM2500 monthly @ 920sq f) versus paying RM720000 to tie you down for next 5,10 or even 20 years.  I am sure you know how to weigh this out.

There is no so called early bird to catch the good worms nowadays as we must be realistic enough - to see the actual built up and justify the good worms.
