Another option would be to consider Starlink. 

There's just so many options out there but the first step is getting that first deal. 

You have 2 solid options!

Metal frame and solid wood.$59.95 Instant Vortex Plus 4qt Air Fryer - https://www.amazon.com/dp/B08R6KMBQT?

Credit unions can also be a good option.

If you can get someone to do this I agree this is a great option. 

So I’m trying to see if I take that equity off the table and re-invest the sale proceeds in another market across more doors where we’ll see better appreciation, OR if we continue keeping it as a rental and work on principal pay down even though the rental price has been coming down and the home is not the easiest to fill because of the above average price for the C- to B neighborhood.Ultimately, my stated goal has been to build appreciation (over cash flow) by acquiring 1-4 doors per year for the next 10 years to allow my wife to retire (or be work optional) by the time she's 50.

Another option you might want to consider is a cash-out refinance on the condo, especially since it's owned free and clear.

What are my options, or do you have any input or suggestions? 

Many of the short-term rentals in Las Vegas were sold during COVID because they were vacant most of the time.Another option to consider is mid-term rentals (MTRs).
