As @Christopher Brainard has expressed above, Las Vegas is a extremely competitive market for wholesaling.

In some states there is a multiplier in between, and some states express the rate as a percentage and others as a mil rate which is a number of dollars of tax per thousand dollars of property value. 

The tenants has expressed a frustration with the parking situation because there are 16 units and 16 parking spaces in the rear of the building which means each unit is entitled to a spot which currently is free.

From hotpads at least you'll get a lot of emails with the persons email and phone number expressing interest, call them back ASAP.

I don't sell any investments and don't have anything to gain and simply expressing my opinion. 

I can't express how important it is to make sure that your agent or broker is well-versed in the facet of real estate you are getting involved in.  

This is a great place to learn which is essential and you can ask questions to those who have done what you expressed you want to do.  

I attended the Express Homebuyers Meetup in Springfield a couple months ago.  

I'm waiting for them to return the letters expressing their intent along with copies of the new lease. 

This situation seems too risky and doesn't align with your father's risk tolerance, considering he expressed interest in taking a withdrawal to pay down his mortgage and live "stress free."
