Since we don’t know how much is in your trust, it’s hard to say. Just be sensible. Buying a $30m Beverly Hills mansion is going to raise alarm bells and get you audited. Plus, the more expensive the house, the more expensive they are to run and maintain. Be modest and keep it simple.
It will also depend on the area you’re looking to buy in. Manhattan prices are going to be wildly different to rural prices, for example.
