Hello & welcome.
Most of the info you need regarding costs can be found on the site. Yes, rent is expensive with a 2 bed apqrtment costing around AED 140k per annum, payable as one cheque in advance.
Many property sales jobs are commission dependent and I know of too many instances where promised commission was not forthcoming. My advice would be to ensure that your role has a decent basic salary. What type of role are you looking at. Many end up being a job where you man a stall in a shopping mall, rather then actual sales.
For information of the ME property market have a look at our sister site

Plenty of young families in Dubai and it is a good place for children as it is relatively safe with little of the yob culture that you see elsewhere. School fees are expensive.
