I also may be overestimating what I could sell it for but l, as always, these are just educated (hopefully) guesses. 

A tenant in one of my townhouses - which are all connected in a condo style within the community - advised my property manager of a leak which is coming from the roof.These are 3 floor units and on the highest floor, there is water leaking through the bathroom light, above the shower, whenever it rains.It barely ever rains in Las Vegas, but lately - with my luck - it's been raining here at least once per week.The HOA is responsible for maintaining the roofs.I quickly advised them of the issue, as did my property manager.They sent a work order to a roofer.

I was thinking SFH buy & hold in our backyard of Las Vegas, rent by room to travel nurse/professionals or potentially Airbnb in Henderson (Airbnb potentially becoming legal in Clark County in July 2022)Thanks in advance!

I manage properties in Las Vegas and Henderson NV. 

Hwy 160 is the main thorougfare from people going to and from Las Vegas and Reno.

It seems everyone that willingly offers to "mentor" here in Las Vegas, charge a going rate of $5,000 cold hard cash, up front.

How do units in luxury las vegas condos on the Strip look like in terms of a real estate investment for a buy and hold investor (as a rental)?

I am a Realtor in Las Vegas and my practice is almost exclusively remote investors.

Don't plant a garden in the common area without permission (and then cry that the contractor drove on it.) 

I have a set of property manager interview questions which I use (I am a Realtor in Las Vegas and my practice is almost exclusively remote investors and I occasionally have to move my clients to a different property manager when the current one starts to go bad.), and I will be happy to send to you.
