So your decision is: do I borrow the money at 6% (subsidized by the tax deduction, which work out to be more like 4.5~5%) to make that investment or do I pass?  

Hi @Lotta Rozenson,In some cases, taking a Section 179 deduction can end up giving you a bigger deduction than bonus depreciation, especially with bonus depreciation being reduced to 80% for 2023, as @Sean O'Keefe mentioned previously.

some investors pushing to get more tax deductions try this to decrease their tax liability that year. 

This will ensure deductions don't slip through the cracks.

You pay it AFTER deducting all expenses related to that rental unit.

That said, for me 60 days notice does nothing for me since I won't advertise or try to show the unit until its vacant and prepped.My recommendation is to discuss with them and if you are honestly aggrieved by the lack of notice and it impacts you discuss a flat fee deduction from the security deposit.

If you buy a house in full, or get a mortgage with the intent of it being a rental investment, is that number tax deductible, and are the renovation costs?

Just to add a bit more, if you are looking for tax benefits like they have in the US ( for example where you can deduct expenses against your employment income in certain cases), unfortunately we don't have that in Canada.

We deduct flooring all at once when replaced following tenant turnover. 

One key piece of a cost segregation study is identifying the land value of your property as it helps you be compliant with the IRS and maximize your deductions and tax benefits.When you purchase a property, the purchase price includes the value of the land, buildings and the components.
