Get your taxes done using TurboTax

Thanks I have two of follow-up questions regarding the business use of home .

As I understand part of the mortgage interest depending on the time and space used can be deducted as expense towards in home child care. 

The first follow-up question is, how about property taxes? Can I deduct property taxes also as an expense towards in home child care business ? 

And second follow-up question is,

If this is a primary residence which is also used for in home childcare, Can I deduct mortgage interest paid towards regular taxable income calculation and also as an expense towards in home child care business? or only one is allowed ?
