Expense Example Narrative [Text Block] oef_ExpenseExampleNarrativeTextBlock
This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover [Text Block] oef_PortfolioTurnoverTextBlock
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 16% of the average value of its portfolio.

Strategy [Heading] oef_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock
Davis Selected Advisers, L.P. (“Davis Advisors” or the “Adviser”), the Fund’s investment adviser, uses the Davis Investment Discipline to invest, under normal market conditions, at least 80% of the Fund’s net assets, plus any borrowing for investment purposes, in securities issued by companies principally engaged in the real estate industry. The Fund invests principally in common stocks of domestic companies and may invest in foreign companies (including indirect holdings of a foreign issuer’s common stock through Depositary Receipts (as defined below)).
A company is principally engaged in the real estate industry if it owns real estate or real estate-related assets that constitute at least 50% of the value of all of its assets, or if it derives at least 50% of its revenues or net profits from owning, financing, developing, managing or selling real estate, or from offering products or services that are related to real estate. Issuers of real estate securities include real estate investment trusts (“REITs”), brokers, developers, lenders and companies with substantial real estate holdings, such as paper, lumber, hotel and entertainment companies. Most of the Fund’s real estate securities are, and will likely continue to be, interests in publicly traded REITs. REITs pool investors’ funds to make real estate-related investments, such as buying interests in income-producing property or making loans to real estate developers.
Davis Investment Discipline. Davis Advisors manages equity funds using the Davis Investment Discipline. Davis Advisors conducts extensive research to try to identify businesses that possess characteristics that Davis Advisors believes foster the creation of long-term value, such as proven management, a durable franchise and business model, and sustainable competitive advantages. Davis Advisors aims to invest in such businesses when they are trading at discounts to their intrinsic worth. Davis Advisors emphasizes individual stock selection and believes that the ability to evaluate management is critical. Davis Advisors routinely visits managers at their places of business in order to gain insight into the relative value of different businesses. Such research, however rigorous, involves predictions and forecasts that are inherently uncertain. After determining which companies Davis Advisors believes the Fund should own, Davis Advisors then turns its analysis to determining the intrinsic value of those companies’ equity securities. Davis Advisors seeks companies whose equity securities can be purchased at a discount from Davis Advisors’ estimate of the company’s intrinsic value based upon fundamental analysis of cash flows, assets
and liabilities, and other criteria that Davis Advisors deems to be material on a company-by-company basis. Davis Advisors’ goal is to invest in companies for the long term (ideally, five years or longer, although this goal may not be met). Davis Advisors considers selling a company’s equity securities if the securities’ market price exceeds Davis Advisors’ estimates of intrinsic value, if the ratio of the risks and rewards of continuing to own the company’s equity securities is no longer attractive, to raise cash to purchase a more attractive investment opportunity, to satisfy net redemptions, or for other purposes.

Risk [Text Block] oef_RiskTextBlock
Common Stock Risk. Common stock represents an ownership position in a company. An adverse event may have a negative impact on a company and could result in a decline in the price of its common stock. Common stock is generally subordinate to an issuer’s other securities, including preferred, convertible, and debt securities.

Risk [Text Block] oef_RiskTextBlock
Real Estate Risk. Real estate securities are susceptible to the many risks associated with the direct ownership of real estate, including declines in property values, increases in property taxes, operating expenses, interest rates or competition, overbuilding, changes in zoning laws, or losses from casualty or condemnation.

Risk [Text Block] oef_RiskTextBlock
Headline Risk. The Fund may invest in a company when the company becomes the center of controversy after receiving adverse media attention concerning its operations, long-term prospects, management, or for other reasons. While Davis Advisors researches companies subject to such contingencies, it cannot be correct every time, and the company’s stock may never recover or may become worthless.
Davis Real Estate Portfolio | Davis Variable Account Fund | Large-Capitalization Companies Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Large-Capitalization Companies Risk. Companies with $10 billion or more in market capitalization are considered by the Adviser to be large-capitalization companies. Large-capitalization companies generally experience slower rates of growth in earnings per share than do mid- and small-capitalization companies.

Risk [Text Block] oef_RiskTextBlock
Manager Risk. Poor security selection or focus on securities in a particular sector, category, or group of companies may cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective. Even if the Adviser implements the intended investment strategies, the implementation of the strategies may be unsuccessful in achieving the Fund’s investment objective.
Davis Real Estate Portfolio | Davis Variable Account Fund | Fees and Expenses Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Fees and Expenses Risk. The Fund may not earn enough through income and capital appreciation to offset the operating expenses of the Fund. All mutual funds incur operating fees and expenses. Fees and expenses reduce the return that a shareholder may earn by investing in a fund, even when a fund has favorable performance. A low-return environment, or a bear market, increases the risk that a shareholder may lose money.
Davis Real Estate Portfolio | Davis Variable Account Fund | Mid- and Small-Capitalization Companies Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Mid- and Small-Capitalization Companies Risk. Companies with less than $10 billion in market capitalization are considered by the Adviser to be mid- or small-capitalization companies. Mid- and small-capitalization companies typically have more limited product lines, markets, and financial resources than larger companies and their securities may trade less frequently and in more limited volume than those of larger, more mature companies.
