depend on your quality requirement 
i did notice chinese sifu (prefer uncle age 50++) will do works more proper like balancing, materials advice & more long-lasting. my house backyard has been done by chinese sifu more than 10years now, no crack, no defect. My neighbor backyard wall has been 5 years+ & now starting cracked line happen, it done by yonger chinese sifi (age around 40). Indo sifu maybe for small portion and minus works can consider, for total contract sum more then 10k then you should consider chinese sifu.

Call this guy, he's good. Hired him for my house reno, no regret. Good luck! Mr Yap 012 329 1682

Super Budget - China Tiles for Wall and non-wet areas
Budget - White Horse
Medium - Goucera
High - MML / Niro Granite

The price and quality matches. U can see the difference when you go into the shop respective showroom. The difference is the density, finishing and thickness. Hence the outcome quality is big difference. Most of the medium and high end type has many different designs that cater to your taste.

Only porch u need to get a higher loading for your vehicles worry it will crack. Other than that no issues. Just don't use super budget ones from china to put on the floor. If crack very troublesome.

No such thing. Only porch is different, others all can be the same for flooring. For wall, any material of tiles can be used. I only used 1 brand for the whole house, just different design.

Some even use the same material for all flooring including porch.

WH. U don't need to worry about the quality, all of them no issues for home use. Budget ones might have consistencies issues as they might not be equal sometimes, but cannot be seen with naked eye unless u use machine to check the inconsistencies.

u pay for what u get. my parents home uses it for more than 20 years no issues at all. tile is one of the most long lasting thing in a house.

For both new house and subsale, to me most important is cover the basics first, e.g electrical,water pipe and LEAKAGE. Test your electrical and water before doing anything. If u got water leak or electrical load is not sufficient, it is important to replace them first before doing anything to cover the walls or floors.

because once u lay ur tiles and repaint them and find out this later, u need to whack the tiles and redo, then repaint. waste of $
Don't think new house handed by developer won't have such issues. Later when u do everything only u realise got these problem is too late
