Ask HN: What would be the perfect solution for Universal Basic Income (UBI)?

Following up on this post: https://news.ycombinator.com/item?id=23993259

I have gone through more than 500 comments and saw a lot of suggestions how UBI can work. A lot of people assume that this is the example how it can work:

Every person will get something like $40.000 yearly as UBI + the salary they earn. But, the biggest challenge is what happens with renting and education prices and if it will go up then.

I was thinking and summarizing that something like this can be a solution:

Every family gets a house (there are well prefabricated houses for less than $40.000) in the first year (something like an Universal Basic House) and then everybody gets something like $40.000 per year.

I would like to hear your opinions and suggestions as it is not so easy to go through 1800 comments and analyze everything.

Thanks.
