400K??..come on, saw some owners are asking 500-550k also..hehehehehe.

lets do a small calculation.

If you buy for 450k, you need another 30k for SNP, stamp and lawyer fees and another 20k for simple renovation which makes the total value 500k.
For 500K mortgage, monthly installment is RM 2100/-. then you have to add up another RM 400 p/m for agent fees and maintenance.
So quit rent, fire insurance and assessment fees needs to bear separately. it is another RM 100 p/m.

So total you need to cover RM 2500/- pm

Now the question is ..can you rent TS for RM 2500 range?? ( bear in mind you are expecting this rent price by only doing basic renovation of 20k, so will a tenant pay RM 2500/-  pm for a such unit ?) Even good properties of YTL (Saffron ) do not fetch RM 2500/- pm

Okay, If you rent TS for RM 1500...every month you have to pump RM 1000/- to cover the mortgage.... and where is the profit??
Ok, waiting 1year - 2 years ?? 3 years?? property is getting older and price appreciation will be on halt one day. by then tenants will move to new condominiums in town and rent start falling.
For 3 years you have to pump 36k just to cover the difference in rental to pay off the mortgage.

So be careful, subsale owner has to rent for atleast RM 2500/-  to breathe peacefully. ... in my opinion there are plenty of choices around for RM 2500 range.

Going further, after 3 years you need to sell atleast 600k for breakeven. if you sell for 700k, you have a profit of 100k after 3 years. hmm.. will it be 700per sqft in this area by then?
Reminding here, TS has more than 600 units, so lot of competition for you to sell a unit for 700k range in another 3 years. There is competition from outside and also from inside TS owners.

And........ after all doing all these doings for 3 years to earn just 100k? managing tenants for 3 years is a nightmare and earning 100k after 3 years cannot justify the efforts you put in.

So think twice before buying from sub-sales, or presurize the initial owners to sell for lower price. tell them they  brought the property for 250-300k range and cannot ask 450k-500K withing 2 yrs just becos there is a LRT next to it.
