Is accelerating amortization beneficial?

[Kevin Phu]

Not sure if this would be the exact section to put this so sorry ahead of time if it isn't.

I was hoping to discuss the idea of making an additional principal only payment on my mortgage every month. I currently have a SFR that I house hack and can easily throw in another few hundred a month extra towards the principal.

How fast would this accelerate the amortization and are there any benefits to it? Should I do something else with the money?

My idea is that since my tenants are helping build that pot of equity, I should contribute to it some also so it can build bigger faster. In the event I need to pull money out, I'll have a larger pot...if that makes sense.
