I’ve used homeexchange.com for a couple of years. It gives you the option of reciprocal swaps - going to each other’s houses at the same time, or at different times. There is also a points system - like Airbnb but with points instead of money. Your property is allocated a certain number of Guest Points based on number of rooms, where it is, etc. You can adjust the number of Points up or down if you want.
I usually use Points, but last year I did a non-reciprocal swap and stayed in an amazing place in Spain for a week. The owner of that property had stayed at my place a couple of months earlier.
It’s great! I’ve just arranged a 15 day holiday split between 2 Canary Islands and my accommodation is costing me nothing! Well, there is an annual fee for Home Exchange, which is about £125. But you make massive savings.
As I live in tied accommodation for work, I swap my own home, which is classed as a second home on the site, so that does make it easier to build up Points.
I’m about to do my third swap on Lanzarote. It’s the man’s primary (own) home. While I’m there, he’ll be staying at another exchange property.
I can thoroughly recommend it - it’s a great way to see the world. If you’re interested in the website I’m a member of, drop me a message as I think I can send you an invitation which either saves money or gives you extra points to use right away.

Oh, and another way you can travel is to be a pet or house sitter. So far, I’ve not managed to find a house sit in a place I’d like to go, but I’ve used house sitters three times now to look after my cats when I’m away. Similar to Home Exchange - you pay an annual fee which let you find sitters and/or sits. This has saved me a fortune in cattery fees!
