Annie Jaffrey. https://www.youtube.com/user/AnnieJaffrey. I love her. She's become one of my favorite gurus she's very sweet and very genuine. She covers a lot of topics from weight loss to the usual.
You cannot deduct passive losses if you do not have any net income from your property rental for the tax year. Passive losses cannot reduce your income from wages, but you can defer the losses to future tax years or deduct any losses carried forward when selling the rental house that generated the loss.
If you are talking US, there is not a separate tax rate on rental income. Rental profits get added into your other taxable income which is subject to a graduated tax rate depending on the total of your taxable income. Rental losses are likely limited as rental income/loss is considered passive for most ordinary taxpayers.
