If you only plan on owning 2-4 properties, then there's really no harm in self-funding them unless you know a better, safer way to make more than the going interest rate on that money (most investment mortgages right now are about 7%, maybe effectively 5.5-6% after taxes depending on your brackets and tax structure).

It reduces the “bouncing ball” effect of tasks being passed between departments. 

How would 7% interest rates in 2025 effect the market conditions for you?
