CY2021	us-gaap	Use Of Estimates UseOfEstimates	The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. These estimates are based on historical experience and on various assumptions about the future that are believed to be reasonable based on all available information. Our reported financial position or results of operations may be materially different under changed conditions or when using different estimates and assumptions, particularly with respect to significant accounting policies. In the event that estimates or assumptions prove to differ from actual results, adjustments are made in subsequent periods to reflect more current information.
CY2021	us-gaap	Concentration Risk Credit Risk ConcentrationRiskCreditRisk	We have a significant concentration in residential real estate and commercial loans within Kansas, Colorado, New Mexico, Texas, and Arizona. When necessary, we perform credit evaluations on our customers' financial condition and often request additional guarantees and forms of collateral from our customers. These financial evaluations require significant judgment and are based on a variety of factors including, but not limited to, current economic trends, historical payment patterns, and bad debt write-off experience. Declines in the local or statewide economies could have an adverse impact on our financial condition. Adverse developments affecting real estate values in one or more of our markets could increase our credit risk associated with our loan portfolio. Additionally, if loans are not repaid according to their terms, the collateral securing the loans, in those cases where real estate serves as the primary collateral, may not have value equal to the amounts owed under the loan.
