I suppose it's all relative
If you after a lot of work and there are prospects of more to come you may go in lower, but if you have a good domestic round, I would be wanting a better hourly rate as that job is a strain on your body.
I have good domestic work and don't go for commercial unless I'm getting more ££££'s
There is still great commercial work out there.
Managed apartment blocks are good for me as are Upper class pubs that demand a really top class job doing.
I find the cutthroat jobs that you can splash and dash on are for those that employ and can go in Lower than us sole traders
