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

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).

A couple options… 1) Coast as is until March for better selling season, more buyers, higher price. 2) Raise the rent at least half way to market.

There are several options for skip tracing to find phone numbers and email addresses.

Explain to him what is happening and your options in whatever you are dealing with.

Is there any surrounding area specifically that you think could be the best option ?

I don't feel like I weighed all my options before purchasing because I was on a tight timeline - so for my next deal this is my question for you: If you're just getting started on your first flip and you had ANY funding source available to you - what would be your recommendations of top 4 funding sources in order of your preference? 

But consult professionals for clarity.I was going to suggest placing the rental property in an LLC, but, I see that is not an option you would consider.
