Currently, we manage approximately 40 short- and mid-term rentals, in addition to a few long-term properties.

In 2019, I launched my own revenue management agency to help Airbnb owners boost their income and achieve greater returns on their short-term rental properties.

The closing kept being delayed and delayed and to make a long story short, after it was suppose to close and I could get no answers from Blue Gate or this agent.  

I am guessing that the tenant may be short on funds to pay twice for Jan, until reimbursed by the old owner, so would first make your case to the old owner who has the funds you are owed and certainly hope once reminded of that will refund them. 

Even legal immigrants are not reliable numbers because they will/may be short-term residents and also do not have the same benefits or detriments of US citizens.

If it's on the higher side you may want to consider it for mid-term or long term rental, but if most stays are below 30 it can be viable for short-term! 

I recommend you read "Long-Distance Real Estate Investing" by David Greene.

I'm looking to build a Casita/poolhouse for use as a short term rental in Summerlin.

I’m also based here and have experience with short-term rentals, property management, and work with investors like yourself.

Moving the house only a short distance on the same lot should be MUCH cheaper than moving it somewhere more distant.
