Not sure why this is any different than refinancing to pay for your son (or son in law) to be in Kollel. I hear it is not uncommon (but don’t know of any actual cases). I do know a person who went into credit card debt (which is worse) to pay for his sons in law to stay in Kollel.
Nebech, but his daughter had her heart set on a Kollel Boy, and he could barely afford it, but she couldn’t get married without it. It was somewhat doable while the economy was running well, but now he is piling up debt, making minimum payments and can’t tell his children to get a job. Nebech.
