• Deduction of tds

I have a taxable income. I have an additional house property which I have not rented/leased.It will give a rent of about Rs. 60000/- per annum if rented.Now will this be added to my income and taxed at the relevant rate? Should I deduct an extra T D S for this amount apart from my regular salary tds and later claim a refund while finalising my tax returns? I want to deduct it during my regular salary tax deductions. Is there any upper limit for deduction of tds? My office accountant says I cannot have a tds more than approx . 10 % of salary.
