Air Conditioning - one central air unit.The basement has one baseboard heater as well.Thanks @Daniel Rosa and @Jaydon H.

I'm in the Air Force and will be stationed in Enid, OK for the next 3+ years.

As well as agreeing with those folk who say $11k closing cost seems way too high, I suggest that the main issue you have (as with any Investor who can get cash out of thin air) is holding out until you find the right bargain (rather than only relying on future value increases which may or may not continue). 

Winter months mean higher prices because of the higher demand, but summer vacationers can be great too (except for John Candy).Rather than chasing potentially profitable deals, figure out who your target market is (an overworked Air Traffic Controller from Atlanta), figure out what they want/need, supply that, then market the property in Atlanta.When you find the property that meets those needs, the ability to rent it for less than 30 days is a bonus.

I was wondering what you think about purchasing a land to build an air bnb investment property in Joshua Tree, CA.

You may not know the difference of the great area but look at the photos, and try to stick with: kitchen is modern, has heat and air conditioning.More time consuming but also free: call a couple property managers in given city; US census detailsPaying: rentometer; rentguide; insurify; 

I currently house hack in Denver, renting out the basement of my house as an Air Bnb, and typically cashflow between $500 and $1,000 per month after expenses.

You said you travel a lot, is that by air (I assume?)

Otherwise, tell them what the rate is for them to stay as a long term Air BNB guest! 

However, if a prior phase II indicates that the indoor air quality violates carcinogenic risk standards, there is no need to perform another phase II before exercising your right to terminate the contract.
