Hello Drew,
I believe the best way to assess whether a property will be profitable is through location and nightly rate.
You can figure out nightly rate estimate for free on a lot of sites or even look around at Airbnb availabilities a month out and see what everyone is charging.
Location is harder to determine. Is there enough tourism and travel to the area? Is this a popular destination for business, families, ect.? Is there only 2 months of travel into the area, and other times of the year it is quite empty or is it year-round?
Is the property conveniently located from things like lakes, beaches, ect. all the popular tourist attractions?
To give you an example, I have 2 properties, 7 minutes apart from one another. One is within a popular tourist resort RIGHT on the ocean. The other is 1 block away from a very popular beach.
However, the one in the resort gets me $450+ a night while the other barely $200 a night. The demand for tourism at the property at the resort is significantly higher and even if only 7 minutes away, the location drives the nightly rate significantly.
Hope this helps!! Cheers!
