If you would really like to explore the sector : why not go and message 10 to 20 operators and offer to look after their property or clean their property for a month in exchange for their knowledge and details on the numbers.

Vrbo has free price automation software.I use Excel for book keeping.I don't pay for any third party software, not really needed on 1 or 2 properties.I charge a little extra for cleaning fee than actual cleaning costs.

In 2019 my mission beach units had average revenue minus cleaning of ~$80k.  

As the owner of the tree, it’s almost always your responsibility for clean-up and debris removal.

When you first approach the homeowners about helping them out of their property, you'll want to let them know that you aren't going to save their mortgage you're just trying to give them a clean escape from having that defaulted mortgage on their credit.

If it costs $500 to fill the oil tank and the tenant leaves it empty, that's $500 less you have to cover unpaid rent, cleaning, and repairs.

@Kristin Boekhoff to add to the great input from @Jason Taken:1) To save money, you really want to clean as little as possible.

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).  

Clean it up a bit to get most bang for the buck add ons and preventative damage items like water leaks.
