I've just begun hosting but have been involved with rental properties for many years here in the US. One of the first things I wanted to understand was the daily rate I would have to net in order to reach a profit. I looked at the site and around the community but I don't see a spreadsheet - especially one you can personalize. So I put together a spreadsheet that you can personalize if you like, as I did. For instance, in Los Angeles, there is a Transient Occupancy Tax (TOT) of 14% in the city (incorporated) and 12% in unincorporated areas outside the city. The Nut I refer to is a complete breakdown of that unit's mortgage, taxes, gardener, rent stabilization fee, gas, electric, water and sewer and a contingency.
Have a look, use it, let me know how you think it can be better.
