L&B I'd check how much of your bond you lose if you elect not to do an exit clean... We were with Elders when DF got deployed at 10 days notice, so we didnt want to spend those few days cleaning, we told them we wanted them to do it... they only charged us $375 for a 4 bed 2 living home..... and that was cleaning out the gutters, mowing and cleaning windows as well $500 sounds a bit OTT

On another note......... I dont clean my oven.....I line my oven top to bottom in Al-foil....... I only ever cleaned an oven once before someone pointed this out the me...... It was the little Chinese lady who used to come to do my nails.....She didnt have a great grasp on english, but after I told her why my nails were so bad she got up, found our al-foil and showed me how to tuck it in behind the brackets for the trays etc......God send! I'll love that lady forever!
Now whenever I notice the foil getting dirty I just change it....... takes about 10 mins tops!
