If you are thinking to join trusted house sitters to get one, very specific sit that you have seen, honestly, your chances are very, very slim.
However, don’t despair, there are always literally thousands of sitting opportunities listed to tempt you. Be warned - trawling through them to find sits you fancy can become addictive
Hand on heart, as a single man it is slightly more difficult to get started but once you have a couple of decent reviews to add to your profile it will get much easier.
To get those all-important first few reviews look out for the not-so-popular sits - they will be clearly marked ‘low applicants’ - preferably any that are not too far from you to save on your travel costs.
For inspiration, click on ‘looking for a sitter’ - look out for any with a picture of a single male and then check out their reviews. The lovely @toml is a great example!!
You are not the first to have had the same concern, here is a thread from a while ago that you may find interesting reading.
Go for it! - Good Luck!
