Hi,
Whatever you do please buy direct from developer and not from resale market. The property pricing of developer varies depending on construction quality.. and it really varies my fren.
The best developer, in my opinion, is Berinda. It is part of Kuok group and the build quality somewhat reminds me of the Allgreen properties in SG.. ok lah not as great but it should be the best in Johor. A double storey terrace house built-up about 2500 sft in Taman Molek (near Molek Pine) costs 488k MYR, and that's not even corner unit. They are still selling some properties near Skudai called Impian Heights... leading to a golf course. Houses are nice and big but location sucks.
UEM's East Ledang is top notch... but they are more into properties about MYR1m... you get land area 90 x 45 ft and house built up ranges from 3300 sft to 4000 sft. It is the best choice if you think it is not crazy to throw this amount of money in bolehland. However i advise against this because very few Singaporeans will invest MYR1m in Johor. You'll probably end up having Arabs and Sri Lankans as your neighbours.
As for Horizon Hills, it is a nice concept. Unfortunately the company actually developing the properties is not UEM, but the engineering company Gamuda. The are listed and have built some properties, but i am afraid i have to say the houses could be much better built. The materials used, the layout... reminds me of commercial buildings. It does not give you a homely feeling. But that can be overcome by doing up the house nicely. I think the pricing is in the region of 500k for a cluster house?
FORGET ABOUT THE OLD JOHOR ie Mount Austin, Pelangi, etc.. areas near to JB city. JB city is like Gotham city you dont want to live near there. If you are interested only in this locality then go for Taman Molek, Taman Ponderosa or Taman Redang. The shops and facilities around Taman Molek are the most "upmarket" compared to the rest of Johor. Even the Ajisen Ramen there are more authentic than the shitty ramen you get at Ajisen at Carrefour Sutera Mall.
As you might have heard, the Johor government admin centre is being moved to Kota Iskandar. This is the new Johor where all the East Ledangs, etc are. Kota Iskandar is a copycat of Putrajaya to a smaller scale. The generic term used to describe this area is Nusajaya. Unfortunately the place will take probably another 10 years before fully developed and "habitable" but this is just my opinion.
Hence the best bet at reasonable price is the locality around Bukit Indah which encompasses Horizon Hills, Nusa Idaman, Nusa Duta, and tons of Setia Indah properties. They are all accessible via exit 307 ie go from Tuas, travel for 10 minutes, turn into JB-Pasir Gudang highway, then exit 308 to Bukit Indah.
Horizon Hills is kinda large and deep and the most expensive of the lot, but it is nestled among golf course hence the best in terms of lifestyle... but mind you everything in JB is notorius for inability to keep up to the originally intended standard, i don't know 10 years down if the place will still look nice.
SP Setia seems to have properties all over Bukit Indah - they are the builder of budget homes. Well they do have more expensive ones but my opinion is, it is better they stick to what they are good at.. ie build small houses for the local Malays. They have lots of selections of double storey terraces with 4 rooms, but only 1600 - 2000 sft! The salespeople treat you as if you are buying a HDB flat, i hate them. I think they are too used to cheapo customers.
Nusa Idaman is the best bet. This is by UEM. When they started phase 2A about 3 years ago, a corner unit built-up 1895 sft (land about 2800 sft) costs just 300k. Almost ALL of them were bought by savvy Singaporeans.
I think the current phases would costs about 400k plus for something similar, but i dont like them because the car porch is very short. Still... i think you can find something decent at a reasonable price. I mean this is Johor, dont spend too much. The access to Nusa Idaman have become a lot easier with the opening of the new highway exit (the one just before Bukit Indah). I recall someone mentioned about the dark road leading up to the access point. No, dont worry at all. The road is call Jalan Ceria, it is now leading up to the entry and exit point to Pasir Gudang highway. In fact just travel a little more you will reach a big coffee shop - the food sucks but there are scantily clad singers bouncing around at night. There is also a mosque next to this coffee shop. But who cares!
If you want something more convenient then go for the property by IJM Land called Nusa Duta. It is right behind the new Giant supermarket, walkable. Cross the road and you are at Tesco. Walk a little further (haha just drive lah) you are at Jusco Bukit Indah.
That is why i recommend New Johor around this area. Quite a coup to have Jusco, Tesco and Giant within a small township.
You could even avoid getting into the ever irritating traffic along Nusa Bestari. Too many vehicles for roads with only 2 lanes each way.
Hope the info is helpful.
