I believe you’ll have a good chance to get 10% yield if you buy from developer (under-construction). Of course, it depends on other factors as well.
If it’s completed/in subsale market, it is fairly difficult to get 10% yield. Normally, you’ll have a better chance with smaller units i.e. studios.
Mostly, sellers will mark-up the price to make the current rental just enough to cover installment. For subsale cases, you can buy now and forecast that rental will increase over time due to huge future office/commercial projects around the area. Urban redevelopment may make an area of low rental to become high in the future. Examples of planned future redevelopment in the news are Kg Baru, Datum Jelatek, Stadium Merdeka area, Jalan Cochrane area & Tamansari.
Examples:
Melur apartment near Sentul LRT. Developer’s price is only about RM120k, but now you can get rental of min RM1000 p/m. Now, market price is about RM220k.
Putra Villa condo (near Gombak LRT) was sold at min RM170k. now can command rental of RM1500 p/m.
Casa Mutiara’s studio is only about RM100k+ when opened to public. In 2007, subsale was around RM160k. Now can get rental min RM1500 p/m.
For Maytower, it’s even lucrative. Capsquare is not even fully opened yet. Same with Amcorp studios.
Similarities from these examples are NEAR TO LRT STATIONS + HIGH-RISE BUILDINGS.
