I'm in AZ, also a community property state, so I have some experience on the subject (learned the hard way).
First thing you have to understand is the difference between ownership and marital interest.
As long as the house is in your name it will always be owned as your sole and separate property.
However, from the moment you are married your new wife will accrue a marital interest in the equity from the date of the marriage onward if certain conditions are met.
Those conditions include paying the mortgage, insurance and property tax from your own income, because once you are married your income is community income just as her income is.
There are two ways to avoid a marital interest accruing to your new wife.
1 - A prenuptial agreement.
2 - Don't use any of your income to support the house. In other words, you will need to have accumulated enough money as your sole and separate money prior to getting married to support the house without using any of that money or its earnings for any marital expenses and not using any money earned during the marriage.
Even your separate bank accounts will not be sole and separate property if you put your earnings into them.
That's overly simplified of course, and you would be wise to consult an attorney for chapter and verse as to how you prevent your sole and separate property from becoming marital property.
Consulting a lawyer now will cost you a pittance compared to what it will cost you later if you don't get it right.
