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.

I should add, while that's CAN be nice to take losses/deductions, its better to actually be positive and make money.If you flip, you are considered dealing in inventory, not an investment property. 

The IRS says to keep records for your business tax deductions indicating:What you boughtWhen you bought itHow much you spentIt doesn't mention requiring paper receipts at all.

You are going to need to research local law on mortgage/deed of trust foreclosures vs. sheriff sales (levies to satisfy judgments).

I offer to pay them a 2.5% commission on the purchase price, deducting it from my assignment fee.Best of luck!

You can deduct as a rental expense 10% of any expense that must be divided between rental use and personal use.
