Would you ever choose to be homeless or live in an RV to avoid the high cost of rent and mortgages

Big political issue in some places these days.
Certainly in the UK.

The government wants to charge rv users rates (taxes) and landowners the 'commercial' rate for business tax.

RV owners need a consistent electricity supply....more expense, either to the landowners or the rv owners (one will no doubt pass any charge on down to the next) so it's not the free lifestyle it used to be.

Gas supply is usually via bottle, which the fire service hate heaven forbid a fire should break out.

And by all accounts it's harder to live like that the older you get because you're more susceptible to cold and illness.

Kudos to anyone trying to make it work.
But yes. I'd consider living that way rather than be homeless.

Id like to build my own house someday .. *sigh* we are sorta living in a shed/house right now 😅 but i like stone buildings

You could rent a room or live with family to save money.. if you can stand that.. mortgage rates are at an all time high these days, it’s the worst .. otherwise buying a house is a good option long term sometimes even less expensive than rent

I'd consider it, as it seems really cool in theory, but I really don't think I'm built for it. I'm not hardy stock, so to speak
