Theoretically, yes, if you own enough gold bullion to use towards a house, that gold bullion can easily be liquidated at market price to use towards the purchase of a home. But do not make the mistake of thinking you can arrive at the Title company with a bunch of gold bullion in tow to close on your home sale. There may be instances in which private sellers would agree to sell their homes in exchange for gold bullion; however, neither party should seriously consider these situations. Some of the issues that could arise in that kind of transaction include: agreeing on value with fluctuating gold prices, assaying, legal and regulatory issues, potential fraud, and future tax issues.
The simplest and most legal way to use your gold bullion to purchase a home is to sell your gold for currency and then use that currency to buy the house. If you want to effectively “buy a house with gold,” you could do so indirectly by selling the gold and then using the proceeds to purchase real estate. If you’re considering such a purchase, you should consult with a financial advisor or real estate professional in your area who better understands the complexities involved.
