They will open road straight to sendayan later

Good choice for Seremban location. This place should appreciate further, even if it is on a slow pace.
You mean Persiaran Sendayan - Mambau? It already exists no? What is the point of wanting that property if you want to use this road to go to another housing area? It's like Rimbayu needing 20 mins to get to Kota Kemuning but the only thing is Rimbayu is trying to make a township with 3 major developers working on that location. There is no way OSK will build a township at Kampung Baru Mambau

beyond my loan range to stretch for Sendayan Value   

You have to remember this. Back in those days when IJM launched S2, no one was going. Everyone was still staying in their homes in Taman Rasah, Senawang, etc cause they were near to Giant, Terminal 1, and Seremban Parade. So IJM continued building and eventually invited Jusco (at that time) and that somehow boosted the sales in Seremban. Took them around 6 years to get their township "hot".

My parents bought their house in Rasah Kemayan in 2003, it was a detached house (50x90 land) for only 330k, and it is going for 2m now LMAO.
