Never rent out to students. They are noisy and will make your neighbours hate you.

Depends on developer.
Most likely between IDU and ODU dont have electrical wiring. If want to pull, pull 4 wires so inverter can be installed properly (LNE+signal). LNE 3 wire cable cannot support 4 function, normally kena modify to LN+signal without earth.

Ok maybe 1.5mm cable which is actually quite cheap, is too expensive for kiamsiap installer.
For power cable (LNE) between IDU and ODU use normal cable, so the ODU is properly earthed.
For signal even using cheap 2-wire twin flat cable (speaker wire) not even RM20 for the whole 60m roll also can jalan properly as LNE+S. Rather than sacrificing earth to run LNS without E.

If your condo is newly vped, there will be plenty of contractors around to choose from. Don't have to purposely ask for recommended contractors. Any contractor can do the job

Tenants are not always determine by individual landlords but others included. A landlord may have a preferred tenant type but because of vacancy factor, many choose the next best option.

A condo near to U will attract mainly students and is the selling point of developers or become a student lodging if a U is build later similar to those condos and terrace around Sg Long TAR U.

There are exceptions thou if landlord can wait for the right one.

Any contractors can do the job? Because my friend kena con by contracter before. The contracter receive so many booking from that property, that during his Unit the contracter do very fast and miss out a lot off details and workmanship not good.
