Hi, my parents have a terrace house in KV that is worth around 600k. They like to plant things and have their own garden so I looked around and found that there are a few areas in Seremban where they sell bungalow lots for people to build their own houses. There are also some double story semi-ds that cost around 400k to 500k. The residential land costs around 200k - 300k.

I'm wondering if it is better to buy a semi-D with around 3500 sqft of land that already has a house built and just spend 50k on basic renovations or buy a 5600 sqft land and build a single story bungalow. The main reason I'm asking this is because I'm not really sure how much it would cost to build a house in Seremban. I heard people say you can build a single story bungalow for 100k, and some say you need 300k.

If they sell their house in KV, they will probably have about 550k left.

Which of the 2 do you guys think is the better option?
