@Kurt Bouma don’t listen to what everyone else is saying your advisor is correct. I worked for many years in finance and specialized in retirement accounts so I know a thing or two. Retirement accounts can only hold securities, so stocks, bonds, even reits but you can not put your house in your portfolio. My series 7 teacher used to say, “you can hold your apple stock in your ira, but grandmas house and your beanie baby collection can not go into the account.” Think of it this way, when you start take RMDs from your account, you are selling off a position to receive funds so youre selling your ownership. If your house is in the account you can’t sell a portion of your house on the secondary market. If you completely liquidated your account, you sold the ownership of your possessions which is impossible with a house because the title/deed never transferred to anyone.
I hope that made sense I’m happy to explain differently if needed.
With that said though, obviously speak to an accountant for this, but you can use funds generally from a 401k (I know you said Ira and yes they are different) as a down payment on a house and people generally confuse that aspect as owning the house as a position in your account.
