I have 18 months before I start making payments, and when I have an abundance mindset, I can just make an extra $80k in 18 months and ay it off and be done with it. 

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.

We also plan on putting in washer and dryer hook ups for that unit and putting in a wall to give them an extra bedroom.

Interest amount you are paying out each month while refi to pull out the money & finding deals are also an extra expense. 5.

Since you're new just be extra careful.

BTW, pretty if she stays an extra day she'd only owe for one day - no court is going to rule for you on that, and you'll look like a jerk of a donkey's hind end for trying.

What @Steve Vaughan and his wife did is perfectly normal and actually streamlines things a little to shave some costs of extra work.

Plus when you move out the extra unit gets rented.

I want to do this all while ensuring my tenants' housing needs are sufficiently met.I'm considering starting with a 5% management fee (and no extra fees), giving the first 3 months of services free as a sort of trial period, and allowing owners to back-out of my services with only a 30-day notice and no extra fees.

It's a hands on learning experience where they can also earn some extra cash.
