Maybe they can't get a mortgage at the moment or for a good few years?!
I get the feeling you're related to one of them so I think it's very unkind to deny them moving to a new home just because you don't like the way they have spent their own savings. They are clearly able to save up a substantial amount, so will be able to do it again when they need to.
I don’t think you’ve read all the updates?
OP isn’t stopping them doing anything, hence the ridiculous splurge on the costs of the wedding.
Refusing to act as a guarantor for a property rental is extremely prudent given they only managed to save this sum because they’ve not paid a penny in rent, bills, food etc. for a few years by living for free with their parents.
OP also mentioned that the costs were spiralling because they’re keen to not look cheap and keep up with the Jones’s/ Insta mob.
Once they move into their own place and have to pay all their own bills, they’ll need to start living within a tight budget especially given their earnings will be fairly low to start with.
At what point are they going to admit to themselves that trying to maintain a champagne lifestyle on a tea budget isn’t realistic. How much debt will they accumulate before they get their ‘ah ha’ moment, if they ever do?
I don’t think OP should act as guarantor but I do think they should ask the couple to work out what their actual budget for everything will be when they move into rented accommodation on the premise that they’re thinking about it.
If the couple have never paid a penny in bills and rent, they are probably completely clueless about how much these things actually cost.
I actually feel sorry for the couple as once financial reality hits, they’re going to be very unhappy.
