What is the profile of buyers here? More Investment or own stayers? Hopefully more own stayers. Good luck to successful buyers.

Be it investor or own stayer, all are given 1 minute to make decision.
This doesn't means that investor can make faster decision, they are forced to do so.

Trust me, astute investors will also considered the points that highlighted by u. Because they need to estimate what their subsales buyers think. The subsales buyers are own stay buyers, investor who know what needed by own stay buyers then only can success.
Astute investors also need the same time as own stay buyers do. The only different is in general, investors are "more experience" and becoz of that it takes lesser time for them to make decision.

Like in retail/trading business, u need to sell what the end users want, not what u want.

nowadays with the usage of LED lighting, we don't need higher ceiling to compensate for the use of plaster ceiling to accommodate the downlights anymore..

let me go home and check the SPA, there's some dimension on the height of the building..

yes if calculate rental yield over historical purchase price is only for owner's own analysis and feel good factor.. overall rental yield must be calculated based on the current market value..

generally, prime landed assets have very low yield, due to the fact that they are very secure properties, hence low risk, hence low return. this is the same scenario for prime commercial shop lots, a lot of them are getting only 3 - 4% yield.

the upside for a low rental yield is that you can either "grow" your rental to achieve a target yield, or there's upside to capital gain / appreciation. therefore a lot of investors relate low yield asset with high capital gain, and vice versa.

another way to look at this is to use this so called yield play to identify below market value properties, for example, a condo in Mont Kiara is achieving a rental yield of 6.5%, but i know that specific area should only command a yield of 5%, therefore it's a good buy because there's potential for capital growth to reflect back the yield to 5%.

yield = rental / market value

always remember to deduct expenses to calculate net yield. no point looking at gross yields (except for quick comparisons).
