Let out a property while renting myself

If my husband and I buy a property together with mortgage, then we let out the property to someone. Let say we receive 1800 pounds each month. But due to mortgage, we need to repay interest to bank, say 500 pounds a month. And we need to rent another for ourseleves to live somewhere, that we need to pay 1600 pounds a month. I wonder if I can take the 1600 pounds I pay as a tax relief? Because that fact is, I didn't not earn anything, I received 1800, but need to pay out 2100 each month. In this case, do I still need to pay tax on the rental I receive?

Hi JR 08,
Please see the guidance at: Work out your rental income when you let property   
Thank you

Not HMRC,...yes you need to pay tax on rental profits as normal, your personal circumstances do not come in to it, you must complete figures for income and expenses on the let property and advise HMRC...your own living situation isnt relevant...same applies to capital gains if/when you come to sell
