You haven't given much to go on. Are you talking about your PPOR and you want to know if you should do the housework this close to Christmas? Or are you talking about a dump that you have bought and it has truckloads of rubbish that needs to be removed? Or are we somewhere inbetween?
We had a relative who died and on selling his house, we got an over-the-counter (pub counter) valuation from a local agent, which was 'wouldn't give you $100K for it in its current condition'.
The grounds were overgrown with weeds and other plants, you could put your hand in a kitchen cupboard and end up wrist-deep in cockroach mess, bathroom needed a good scrub, other cupboards were full of ltrs received several years ago (nothing was ever thrown out).
A few weekends with a chainsaw, mower, rubbish skip and the same agent bought it for $160K a month later.
