those tamans behind Sentral Residence (SR) were developed >20yrs back. not sure the how high the rental being fetched at the moment.
'bout the u-turn, there have been numerous outcries to force SILK to build a bypass tunnel across the highway (directly to Kajang Utama). now, ppl need to go to Kajang Utama had to make the long u-turn (
before the toll). then suddenly the plan got scraped/KIVed (??)
and yes, if heading to cyberjaya/puchong via sg ramal, need to pay the other RM1 toll. in fact, this toll is worth it. prior to SILK, most southern Kajang ppl need to go thru Bangi to exit the kajang town. now, pay RM1 toll, immediately exit to PLUS highway or to cyberjaya/putrajaya -> puchong/subang or SKVE.
'bout distance to future MRT/KTM, about <1KM is correct. however, you'll be walking under the sun, using side road of Jalan Bukit heading Kajang town. not sure how is the parking system for future MRT, but for KTM, it's not huge. most ppl parked roadside outside of the KTM fence. ermrmm mind you, i got a neighbor who got his myvi stolen just being parked outside and go to colleage at KL.
