Are there any hidden pitfalls or unexpected benefits I might have missed?

I had the same thing, but it seemed to be an accident.

Hey @Joshua SmithWhat was the unexpected issue in my first house hack?

There were a few slight distractions like figuring out financing, selling a neighboring lot (that I had also acquired via letter writing) on Craigslist, rent out my RV, rent out my house, make my first ever documentary film (a twenty minute short called Kara, Star Of The World about a woman with a traumatic brain injury from a childhood ski accident), take any photo and video work I could get, start a 360 photography company, create social media channels to hype the build, parent two small kids, do a beautiful and excruciating tandem mountain bike ride across Scotland, drive my family on RV trips to Colorado/Arizona/Utah/Nevada/California/Wisconsin/Minnesota/Michigan/Florida, attempt to write a novel and adopt a puppy.The above may read as humble brag, it is not.

The electric bill came up unexpected that month7.

Less leverage means that the greater cash flow can more easily cover unexpected expenses without di[ping into capital reserves or personal cash, hence less stress.  

60 day turn around, I put 90 just to allow for the unexpected. 30 day reno timeline as per my contractor.Help!

Actually, timelines are 99% of the time shattered by unexpected work and change orders constantly popping up.

That will bring odors and accidents.

There is nothing that ruins a business relationship quicker than poor communication and unexpected fees.Some PMs add a flat fee or a percentage on top of maintenance bills.
