Ice check for the big items that cost a bomb- white ants, structural issues, asbestos (only an issue if its damaged or you want to move it/renos).
Check that the doors and windows all open and close, otherwise you may be looking at restumping needed (do the floors slope down or are uneven).
Water damage on ceilings, lifting or cracked tiles in the kitchen and bathroom.
Evidence of new paint work or patching on the walls, especially on walls adjacent to taps or sinks in another room (if that makes sense).
Anything that looks like flood or storm damage.
Does it look like someone has looked after it? Or does it look like an unloved rental?
Oh, and depending on where you live (hello, Sydney)- cockroaches in plague proportions?
I should've read through the thread further! Im a numpty!
