Accounting Policies [Abstract]
Basis of presentation	Basis of presentation The financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”).
Management estimates	Management estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions about the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities, at the dates of the financial statements and the reported amounts of revenues and expenses during the reported periods. Such estimates involve a significant level of uncertainty and have had or are reasonably likely to have a material impact on the company’s financial condition or results of operations. Such estimates relate principally to the determination of the allowance for credit losses (including the fair value of the collateral), and the valuation of real estate owned (“REO”) at acquisition and subsequently (RMI IX has not acquired REO since it commenced operations in 2009). Actual results could differ materially from these estimates.
Fair value estimates	Fair value estimates The fair value of real property (as to loan collateral and REO) is determined by exercise of judgment based on RMC’s management’s experience informed by appraisals (by licensed appraisers), brokers’ opinion of values, and publicly available information on in-market transactions. Appraisals of commercial real property generally present three approaches to estimating value: 1) market-comparables or sales approach; 2) cost to replace; and 3) capitalized cash flows or income approach. These approaches may or may not result in a common, single value. The market-comparables approach may yield different values depending on certain basic assumptions, including the consideration of adjustments made for any attributes specific to the real estate. Management has the requisite familiarity with the markets it lends in generally and of the properties lent on specifically to analyze sales-comparables and assess their suitability/applicability. Management is acquainted with market participants – investors, developers, brokers, and lenders – that are useful, relevant secondary sources of data and information regarding valuation and valuation variability. These secondary sources may have familiarity with and perspectives on pending transactions, successful strategies to optimize value, and the history and details of specific properties – on and off the market – that enhance the process and analysis that is particularly and principally germane to establishing value in distressed markets and/or property types. GAAP defines fair value as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact and (iv) willing to transact. Fair values of assets and liabilities are determined based on the fair-value hierarchy established in GAAP. The hierarchy is comprised of three levels of inputs to be used: • Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the company has the ability to access at the measurement date. An active market is a market in which transactions occur with sufficient frequency and volume to provide pricing information on an ongoing basis. • Level 2 inputs are inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly in active markets and quoted prices for identical assets or liabilities that are not active, and inputs other than quoted prices that are observable, or inputs derived from or corroborated by market data. • Level 3 inputs are unobservable inputs for the asset or liability. Unobservable inputs reflect the company’s own assumptions about the assumptions market participants would use in pricing the asset or liability (including assumptions about risk). Unobservable inputs are developed based on the best information available in the circumstances and may include the company’s own data.
Cash in banks	Cash in banks Certain of the company’s cash balances in banks exceed federally insured limits. The bank or banks in which funds are deposited are reviewed periodically for their general creditworthiness/investment grade credit rating.
Loans and interest income	Loans and interest income Loans are carried at amortized cost, which is generally equal to the unpaid principal balance (principal). The company may fund a specific loan net of an interest reserve (one to two years) to insure timely interest payments at the inception of the loan. Any interest reserve is amortized over the period that the amount is prepaid. In the event of an early loan payoff, any unapplied interest reserves would be first applied to any accrued but unpaid interest and then as a reduction to the principal. Payments on loans are applied in the following order: accrued interest, advances, and lastly to principal. Late fees and post-maturity/default interest are recognized in the period received, as collectability is not assured until then. Amounts are calculated based on the terms of the note. Pursuant to California regulatory requirements, borrower payments are deposited into a trust account established by RMC with an independent bank (and are presented on the balance sheet as “Loan payments in trust”). Funds are disbursed to the company’s bank account as collected, which can range from same day for wire transfers and to two weeks after deposit for checks. The company funds loans with the intent to hold until maturity. From time to time the company may sell certain loans to unaffiliated third parties. Loans are classified as held-for-sale once a decision has been made to sell loans and the loans to be held-for-sale have been identified. Loans classified as held-for-sale are carried at the lower of amortized cost or fair value. Performing loans that are maturing or have matured may be renewed at then current market rates of interest and terms for new loans. Such loan extensions are typically deemed to be modifications rather than new originations under GAAP per the manager’s evaluation of the changes to terms of the notes. Loans are placed on non-accrual status when the manager determines that the primary source of repayment will come from the acquisition by foreclosure (or acquisition by deed in lieu of foreclosure) and subsequent sale of the collateral securing the loan (e.g., a notice of sale is filed and/or when a borrower files for bankruptcy) or when the loan is no longer considered well-secured (i.e., the LTV for the loan based on the estimated net realizable value of the collateral and the total principal, advances and accrued interest (at the note rate) is at or greater than eighty percent (80%), seventy-five percent (75%) for lands outside of metropolitan areas) and the borrower has payments in arrears. When a loan is placed on non-accrual status, the accrual of interest is discontinued – beginning with the then current month – for accounting purposes only; previously recorded interest is not reversed. A loan may return to accrual status when all delinquent loan payments are cured and the loan becomes current in accordance with the terms of the loan agreement and the loan balance is considered well collateralized.
Allowance for credit losses	Allowance for credit losses The allowance for credit losses is recognized based on current expected lifetime credit losses at the time a loan is originated or acquired. For RMI IX’s loans, generally no loss is expected at origination, given the substantial protective equity (resulting from low LTVs), the predominance of first lien loans, the short duration of the loans, and the property-type and location of the collateral. The present fair values of the collateral are reassessed periodically (determined by the manager’s assessment of markets and/or property types that are deemed possibly to have changed and the time since the last valuation of the loan’s collateral) and the resultant protective equity for each loan is determined. As used herein, “protective equity” is the dollar amount by which the net realizable value (i.e., fair value less the cost to sell) of the collateral, net of any senior liens and claims, exceeds the loan balance. Loan balances (as stated on the Balance Sheets, is the sum of principal, advances and interest) are analyzed on a periodic basis for ultimate recoverability, and the allowance for credit losses is adjusted each period for changes in expected credit losses. The ultimate collectability of the amounts owed is reliant on the estimation of the present fair value of the real property collateral and the remaining time to maturity. The determination of the probability-of-loss (and, accordingly, the determination of the amount of the allowance for expected credit losses) considers current fair value of collateral and the resultant protective equity, the time to maturity, the lien position, current real estate and financial markets, as well as reasonable and supportable forecasts about future economic scenarios and – to a lesser extent – historical loss experience. The forward-looking estimates consider the likelihood that any combination of events would adversely impact economic conditions and real estate markets in California such that the substantial protective equity existing for the loans would no longer be sufficient to collect the recorded amounts of principal, advances and accrued interest due on the loan. Expected credit losses are determined on a collective (pool) basis when similar risk characteristic(s) exist. When determining risk characteristics to include in its pooling assessment, the following are most determinant. - LTV: The ratio of the outstanding loan balance to the fair value of the underlying collateral, and thereby the amount of protective equity of the company’s loans, is the most determinant attribute at inception of the loan and ongoing in estimating incurred and lifetime expected credit losses. Further to reducing the risk of loss, the company’s loans are predominantly first mortgages, but second lien deeds of trust are not infrequent nor insignificant. - Term: The duration (or expected term) of loan is a determinant attribute as the duration of the company’s loans are less than those of other conventional commercial real estate lenders (e.g., institutions, such as banks, insurance companies, private equity firms), typically in the range of one to three years. The expected duration of the loans (and thereby the forecast period) is shortened further as the loans are written without a prepayment penalty. - Location and property type: The company’s loans are secured by commercial and residential real estate in coastal California metropolitan areas, typically in the Bay Area (including Silicon Valley) but also elsewhere in Northern and Southern California. Given the limited number of loans and the short terms for which the loans are written (and the potentially even shorter duration given that the loans are written without a prepayment penalty), at each reporting date the company performs a risk analysis as to real estate market conditions (by property type) in the California areas in which loan collateral is located and performs a loan-by-loan analysis to determine the current net realizable value of the real property collateral and the remaining time to maturity. Loans with similar LTVs are included in pools and the weighted average LTVs in forward periods are forecasted – by lien position – for those loans expected (on a contractual maturity basis) to be then outstanding. No expected extensions, renewals, or modifications are factored in as the company’s loans do not contain renewal options that can be unconditionally exercised by the borrowers. This methodology/analysis determines if there is any amount outstanding in any future period in the contractual lifetime of the loan(s) in which a real estate market decline in values is expected to occur that would be sufficient to put at risk – given the protective equity provided by the excess of the net realizable value of the collateral to the loan balance at origination – the collection in full of amounts owed, including accrued interest and advances, if any, secured by the deeds of trust. For loans (and/or pools of loans) for which the LTVs are such that a loss within the contractual lifetime is expected, loan by loan analyses are undertaken using the likelihood of loss and the percentage (and/or amount) of the loss to determine the expected loss. In arriving at the market determinations above, the manager consults a range of banking, industry and academic studies and forecasts. If foreclosure (or negotiation of a deed in lieu of foreclosure) is concluded to be probable, the loan is considered to be collateral-dependent and the recorded investment in the loan would be adjusted to an amount not to exceed the net realizable value of the real estate and other assets to be acquired, net of senior liens/mortgage debt plus the liabilities to be assumed. The determination of whether a loan is determined to be collateral-dependent requires judgment and considers the status of the loan (i.e., legal action is undertaken to enforce the lender’s rights to repayment) and the status of the borrower (e.g. has the borrower filed for bankruptcy protection). For a loan that is deemed collateral dependent for repayment, a provision for credit losses is recorded, if necessary, to adjust the allowance for credit losses by an amount such that the net carrying amount (the loan balance, net of foregone interest for loans in non-accrual status) would be reduced to the lower of the net realizable value of the related collateral, net of any senior liens or the loan balance. Uncollectible loans are charged off directly to the allowance for credit losses once it is determined the full amount is not collectible. Any amounts collected after a charge off is deemed a recovery.
Real estate owned (REO)	Real estate owned (“REO”) Real estate owned, or REO, is property acquired in full or partial settlement of loan obligations generally through foreclosure and is recorded at acquisition at the property’s fair value less estimated costs to sell, as are other assets acquired and liabilities assumed (or any senior debt the property is taken subject to). The fair value estimates are derived from information available in the real estate markets including similar property, and often require the experience and judgment of third parties such as commercial real estate appraisers and brokers. The estimates figure materially in calculating the value of the property at acquisition, the level of charge to the allowance for credit losses and any subsequent valuation reserves. After acquisition, costs incurred relating to the development and improvement of property are capitalized to the extent they do not cause the recorded value to exceed the net realizable value, whereas costs relating to holding and disposition of the property are expensed as incurred. REO is analyzed periodically for changes in fair values and any subsequent write down is charged to operations expenses. Any recovery in the fair value subsequent to such a write down is recorded and is not to exceed the value recorded at acquisition. Recognition of gains or losses on the sale of real estate is dependent upon the transaction meeting certain criteria related to the nature of the property and the terms of the sale including potential seller financing.
Debt issuance costs	Debt issuance costs Debt issuance costs are the fees and commissions incurred in the course of obtaining a line of credit for services from banks, law firms and other professionals and are amortized on a straight-line basis as interest expense over the term of the line of credit.
Recent accounting pronouncements not yet adopted	Recent accounting pronouncements not yet adopted In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40) which requires disclosure, in the notes to financial statements, of specified information about certain costs and expenses. The amendments in this update are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, and are expected to require little, if any, additional disclosure for the company.

GAAP defines fair value as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact and (iv) willing to transact.

Fair values of assets and liabilities are determined based on the fair-value hierarchy established in GAAP. The hierarchy is comprised of three levels of inputs to be used:

•

Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the company has the ability to access at the measurement date. An active market is a market in which transactions occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

•

Level 2 inputs are inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly in active markets and quoted prices for identical assets or liabilities that are not active, and inputs other than quoted prices that are observable, or inputs derived from or corroborated by market data.

•

Level 3 inputs are unobservable inputs for the asset or liability. Unobservable inputs reflect the company’s own assumptions about the assumptions market participants would use in pricing the asset or liability (including assumptions about risk). Unobservable inputs are developed based on the best information available in the circumstances and may include the company’s own data.

Cash in banks

REO is analyzed periodically for changes in fair values and any subsequent write down is charged to operations expenses. Any recovery in the fair value subsequent to such a write down is recorded and is not to exceed the value recorded at acquisition. Recognition of gains or losses on the sale of real estate is dependent upon the transaction meeting certain criteria related to the nature of the property and the terms of the sale including potential seller financing.

Debt issuance costs

Debt issuance costs are the fees and commissions incurred in the course of obtaining a line of credit for services from banks, law firms and other professionals and are amortized on a straight-line basis as interest expense over the term of the line of credit.

Recent accounting pronouncements not yet adopted

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40) which requires disclosure, in the notes to financial statements, of specified information about certain costs and expenses. The amendments in this update are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, and are expected to require little, if any, additional disclosure for the company.
