Sadly, the well-intentioned gifting, to adult kids, of a hundred grand to help with their down payment on a home, is actually gasoline on a fire. 

That gifting actually just pushes prices up for the whole market. At the end of the day you do not "help" your kids: You just contribute to a new higher set point for prices overall, and thus the market will simply incorporate an "expectation", an "it goes without saying" that parental funds will toss in a hundred grand towards the needed huge down payment.

It is actually poison to the economy overall, because every dollar stuck in the inflated value of a house mortgage, that's a dollar that is not buying the services and goods that employ neighbours, that yield jobs. Indeed, if we stuck 100 percent of all available dollars in house mortgages, we would buy nothing that translates into jobs for neighbours.

It is not a good direction this is taking. And overseas money flooding in is just more gasoline. Future generations will pay the price.
