Congrats on your new investment.
I own a condo in Princeville, Hawaii. 3bedroom/3bathroom.
I would just figure out what my break even is each month. For me that is booking 15 nights. My monthly fees are as follows (handyman inspection $125, Cleaning $270 a turn (I collect this from guest), TAT&GET (collected from guest) Property Taxes, Insurance (I highly recommend you price this out, with hazard I pay $1,200 a year), internet/cable $100, Electricity $300 a month, AOAO dues $900 (association fees are increasing minimum 5% a year). If you have a management company be sure to underwrite their fees as well. Managers can take a big cut.
I addition I would like to share a few realities with you. I am in the market for replacing my carpet and the cost for carpeting 1,100 SF is $8,000. Repairs and Maintenance are not cheap and shipping carpet/furniture/etc to Hawaii calls for huge price premium so I would be sure keep a reserve for replacements.
As for a downward shift you can always lower your rate (underwrite a worst, middle and best case scenario), Make sure your rental stands out from the crowd (easy to do in Hawaii since most owners don't reinvest in their property). Consider how your property would do as a LTR and underwrite those numbers (worst, middle and best case).
I am very happy with my investment but it has been a lot of work and many challenges managing it from California. I bought in 2013 and I plan to double down on the market when there is a shift.
