Payoff extra principal or save for next purchase?

[Kyle Wegener]

I just purchased a multifamily property (my first ever home purchase) as a house hack and with my disposable income I am deciding on whether I should pay extra principle on my mortgage or put more into savings for my next purchase.

I am comfortably able to double the amount I pay on my principal each month and still save a nice chunk at the same time as I want to buy another property in the next few years.

Being that my main focus is building a portfolio I feel instead I should just pay an extra $100 on principal as it will be beneficial, and then save as much as I can to build up my savings.

Is there a certain percentage to pay extra on principal each month that would be the sweet spot to get the best of both worlds?
