On top of that, one of our goals for life post FI/RE is travel, especially since we're both fortunate to be able to work remotely (one of us is an IT consultant, the other is a project manager consultant (PMP) and corporate trainer.
So, we started to look for creative and unconventional ways on how we could further cut our housing costs, travel, and have a similar quality of life. As the old saying goes... eating our cake while retaining it too!

From house sitting and RV'ing, to work exchanges, volunteering, and travel hacking and co-housing, nothing was off the table.
In 2016, after careful consideration we eventually settled on house sitting as the best 'fit' for us. In our first year of pursuing FI/RE and concurrent long-term travel, we completed 18 house sits and found that we very much enjoyed it. It allows us to travel, explore new places, live like a local, make life long friends (in some cases), and take care of pets with varying personalities that we get to play with, pet, and love.
Fast forward to the present and we’ve been on the road for three and a half years (four continents, 26 countries, and ~80 cities) all while having the pleasure of doing over 60 house sits.
The costs savings when house sitting, as we suspected, can be phenomenal (and spill over to more than just housing/lodging). For perspective our total 2019 housing/lodging costs were $293.38 and our yearly budget (all-in) was $7,000 ($3,500 each), and that includes 'living' in places like Alexandria, Philadelphia, Chicago, Atlanta, and a few months in New York City.
With that being said, it's not all rainbows and butterflies! House sitting can come with its fair share of challenges and work. Although, some will have you believe it's free lodging OMG! it’s way more involved than simply ‘a free place to sleep while traveling’ (it’s not a hotel or Airbnb after all), you need to weigh the pros, cons, amenities, etc. of every house sit and choose wisely.
We don't plan on doing this for the rest of our lives but we're curious, are others that are mindful of their fiances and pursuing FI/RE (especially the ERE flavor) applying 'extreme/unconventional' housing tactics to keep their budgets low? Any lessons learned, mistakes to avoid, or tips for your specific approach?
