These hotels are almost all ideally located right on the strip, and loaded with amenities like room service, restaurants, bars, and casinos. 

Higher-end finishes and staging make sense for a flip but aren’t always ideal for a rental.

This would be ideal in terms of cash flow (after a few years) and equity appreciation since you'd be achieving tremendous returns on limited equity in the form of appreciation, principal paydown and tax benefits aside from only cash flow. 

I've been a long-time renter in the Portland, Oregon market and would love to purchase my first house hack next year: a duplex or triplex, ideally. 

I think my ideal investment is a fix up duplex.

If so, flipping or active investing would be ideal.

In this IDEAL situation the savings is minimal.

Ideally, you'd want closer to $40k-$50k to feel truly comfortable and have a safety net for your first investment property.
