These are the platforms we have joined:
Before we get into details about these choices, please consider the part of the process that may take the most time. You need references to get started, so ask for these early on to give folks time to write them for you. If you have experience, certainly ask for those references. However, if you have no experience, no worries. Everybody has to start somewhere. Character references are fine at the start. Anyone who can speak to your level of maturity and responsibility can do this for you. This includes mentioning your work history, homeownership and pet ownership. I also requested references from the animal shelter where I had volunteered.
The yearly fee is $50 and we have obtained two housesits from them. I believe the general public can see all listings without joining. So again, you can just watch the listings for a while if you are just thinking about getting started. The only downside to this is that when you find an opportunity you want to apply for, you then must create your profile, upload pictures and upload references. Based in Australia, this is the longest running platform, starting in 2000.
This is a world-wide platform that charges $25 per year. We secured our amazing Tonga island sitting adventure here. We applied for another South Pacific opportunity here as well as a house sit in Botswana, Africa! The timing on the latter two turned out to not work for us, so we had to politely decline pursuing them further. There are exotic opportunities on all of the platforms, but this is where we have found the best ones for us.
This world-wide platform charges $20 per year to join. While we personally have not secured any opportunities through this site, I check it daily and see plenty of great activity.
The cost to register is $30 per year. We have not secured any house sits through this site, but interestingly we have been contacted by a number of homeowners directly. They approached us before posting on the website. I beleive all the platforms allow this option. It is nice when a homeowner asks you, instead of you competing with other housesitters. This is the only major platform I am aware of that is focused solely in the US.
