Big companies are moving and developing here like Intel, Meta, Google, Amazon, etc. and population and jobs are growing.

My thought is I buy a multi-fam (off market preferably) and house hack for 2 years then move south.

(They have the deferred maintenance you'd expect after a fixed income senior lived in them for several years, plus smokers, pets)So how do I turn 5 straggling houses into a proper real estate portfolio and well-managed rental business? 

It works the exact same way and it's the same exact lease with one difference - they specify that they are renting a bedroom and not the whole house. 

I have a house, I plan to sell this spring.

Despite this, continued population and job growth, along with limited new development beyond 2025, suggests potential for renewed rent growth in the medium term.The market's long-term outlook remains positive, with Las Vegas's continued growth driving demand for townhomes and condos, making it a viable investment area for both short-term gains and long-term stability.

I closed on the house already.

The specific location ( 4' * 6' long) is underneath a guest bedroom window in the front of the house. 

Currently listed 2 houses 1.5m each and the market is dead.

This has taken years of work and effort to develop these connections.
