But wouldn't it be that even if the overall rental at the area is low, the MRT being attached to this project by a bridge would mean that Meta City would be the 1st choice of any potential renters?

The other projects in the area doesn't have this main advantage, so if there was a person looking to rent in the area and commute to work or college either in Cyberjaya or KL by public transport, the walkability to the MRT would be the biggest factor - which makes Meta City the 1st choice

I may be naive in this, but I'm considering to buy a unit here because of this - any advice from the gurus here would be appreciated

I don't think he's neutral.

The rental in the area for soho sized units is about RM1,200 for fully furnished units. I see that it can go as low as 800, 900 but if you place a premium on Meta City for the location, connectivity - I think RM1,200 for the SOHO unit is a fair price. Repayment on 90% loan + Maintenance + Sinking fund is RM1,352.18 assuming the interest rate is 4.5%. So rental income wise, the place isn't that attractive even if you get tenants - unless you really can make AirBnB successful here.

Capital apreciation, yes - it is possible but with so many unsold units around town (25% unsold in Selangor), who wants to pay half a million for a 1 bedroom SOHO in Seri Kembangan? The rule of thumb usually for property is 5% capital apreciation per year, but I wonder if it's really applicable in the current situation?
