Air DNA rated my area a B+ for STR and I furnished the property listed it on Air bnb and got a 1 week long reservation 2 days after listing. 1 year later and the business is thriving.

Seeing as you are traveling a lot, it might be harder to manage it yourself as you might be in the air when you need to check in.

I have learned a lot about maintaining an elevator, fire alarm system, public restrooms, boiler system, commercial air conditioners and most of all the different laws for commercial tenants vs residential tenants.

It’s a duplex in SD that would be perfect to house hack and air bnb.

I want to get a property and use it as a vacation rental/air bnb.

You don’t use “rules of thumb” or average price per sf pulled out of thin air to estimate rehab costs.

You can make minor adjustments based on the type of appliances (dishwasher, clothes washer and dryer, air conditioning, etc.) and the size of the rental.

Unless the fed cuts rates again, then the air can reinflate the phantom equity. 

Travelers will say Air BnB is responsible as you have a service agreement with them that's supposed to provide coverage for this.
