Cashing out in this seller's market...what to do with the Ca$h?

[Eliza Alexa]

I "try" investing with the knowledge I get from BiggerPockets.   I bought a Vegas townhome cash  in the middle of the RE crash during the GFC of 2008-just as you guys taught.  The Property increased by 147k .  (SIDE NOTE: I lived there & had income using it as a room househack  at first & then a full rental after another RE purchase- just as you guys taught) 

Numbers & market say sell the home however, the property is literally 3 blocks from strip, to airport & UNLV-location, location, location-therefore confused on sell/don't sell. 

If the answer is to sell then what to do with the money?  I want to go to the next level- I just don't know how.  I would like to know what the Professional Investors are doing & maybe I do the same.
