Agreed with your point AN however my assumption was that this person does have rainy day money. The original post said that the 400k that the person sunk into his new home was all from the sale of his previous home.
Absolutely agreed that if there is no rainy day money then no this shouldn’t be done. Again, I made that assumption based on what was written in the post. Conversely the guy could/should put the 2k that he is saving each month, away or invest it conservatively as well.
