Thank you, Ken. For the third quarter of 2020, we reported total revenues of approximately $13.8 million, compared to $14.9 million for Q3 2019. Net loss per Beneficial Unit Certificate, or BUC, basic and diluted, was $0.03 per BUC, compared to a net income of $0.07 per BUC in Q3 2019. And our cash available for distribution, or CAD, was $0.06 per BUC for the current quarter, compared to $0.20 per BUC in Q3 2020.
The net loss for Q3 2020 is due to a $3.5 million impairment of the Live 929 Apartments mortgage revenue bond and an $811,000 loan loss allowance for a Live 929 Apartments property loan. As Ken mentioned, we're considering forbearance requests related to that property due to continued covenant forbearance and a decline in debt service coverage that has been exacerbated by the impacts of COVID-19. Consistent with our CAD policy, such noncash impairments are added back in the calculation of CAD, as management will work to recover such impairments through future management of the assets.
On a year-to-date basis, we reported total revenues of $42.1 million in 2020, compared to $46.9 million for 2019. Net income per BUC, basic and diluted, was $0.07 per BUC, compared to $0.26 per BUC in 2019. And CAD of $0.20 per BUC in 2020 compared to $0.39 per BUC in 2019.
In terms of our investments, ATAX reported over $1.17 billion in total assets as of September 30, 2020. Our assets are primarily comprised of our 3 main investment classes: the first being our net spread portfolio; the second, our Vantage investments; and third, our MF Properties investments.
Our net spread portfolio is primarily comprised of our mortgage revenue bonds, or MRBs, and governmental issuer loan investments. As of September 30, 2020, our mortgage revenue bonds totaled approximately $796 million, or 68% of total assets. This number represents 77 individual mortgage revenue bonds across 13 states. We hold significant amounts of MRBs related to properties located in Texas, at 43% of our total MRBs; California, at 17%; and South Carolina, at 17%.
As Ken mentioned, we acquired one MRB in the third quarter related to a 75-unit affordable multifamily property in Brawley, California, and we have provided a forward commitment to provide permanent financing to a 45-unit seniors multifamily property in San Diego, California.
As of September 30, 2020, we had investments in 3 governmental issuer loans to finance the construction, lease-up and stabilization of affordable multifamily properties in Midland, Texas; Roseville, Minnesota; and Centennial, Colorado. The governmental issuer loans are functionally equivalent to our MRBs, in that they are nonrecourse obligations issued by governmental authorities secured by a mortgage on the property of an affordable multifamily project and we expect and believe the interest earned on governmental issuer loans to be exempt from federal income tax.
At September 30, the 3 governmental issuer loans had a total carrying value of approximately $62 million, and we had outstanding commitments to fund additional proceeds of approximately $45 million during the remainder of construction.
All of our MRBs and governmental issuer loans were current on contractual principal and interest payments through October 2020. As Ken mentioned, to date we have received no forbearance requests of principal and interest related to MRBs and governmental issuer loans associated with multifamily properties. However, we have received forbearance requests related to the student housing MRB of Live 929 Apartments and a forbearance request related to our sole commercial property MRB, called Pro Nova, which is a proton therapy cancer center in Knoxville, Tennessee.
As of September 30, 2020, we had investments in unconsolidated entities, commonly referred to as our Vantage investments, related to 10 market-rate multifamily projects. Our carrying value of these investments was approximately $99.2 million. These projects represent in the aggregate almost 2,900 rental units, with the 10 current projects being 5 in Texas, 2 in Nebraska, 2 in Tennessee, and 1 in South Carolina.
As of September 30, 6 projects were completed and in lease-up, and 4 were under construction. All projects in lease-up have achieved increasing occupancy during the third quarter of 2020. For those under construction, there have been no material delays or disruptions on construction due to COVID-19.
Since our first Vantage investments in late 2015, 6 of ATAX's Vantage investments have been sold or redeemed, resulting in total gain on sale and contingent interest of approximately $27 million for the benefit of our unitholders, providing the proof of concept of the Vantage investment strategy.
As of September 30, 2020, we own 2 MF Properties, consisting of 859 units, with a total net carrying value of approximately $60 million. Both properties serve primarily college students, which, as we have previously noted, has been more significantly impacted by COVID-19 than the general multifamily housing market.
The 50/50 MF Property primarily serves students at the University of Nebraska-Lincoln, which is currently holding on-campus and in-person classes. The property is approximately 86% occupied as of September 30 and is meeting all mortgage and operating obligations with cash flow from operations.
The Suites on Paseo MF Property primarily serves students at San Diego State University, which has suspended on-campus in-person classes for the fall 2020 and spring 2021 semesters. The property is 64% occupied as of September 30 and is meeting all operating obligations with cash flows from operations. The property has no debt obligations at this time.
Moving to the liability side of our balance sheet, our debt financing associated with mortgage revenue bonds and governmental issuer loans totaled approximately $667 million as of September 30, 2020. In July 2020, we extended the maturity dates of 10 of our variable-rate TOB Trust financings that were set to mature in 2021 to July of 2023. These extensions provide us with longer-term liquidity commitments, with no change in interest rate terms.
Also in July 2020, we extended the maturity of our 2 lines of credit with Bankers Trust. One is an unsecured acquisition line of credit of $50 million which provides a short-term source of funding for our investments. The second is an unsecured operating line of credit totaling $10 million. Both lines of credit were extended to June of 2022.
Our most significant debt financing transaction during the third quarter was the issuance of approximately $103 million of secured notes to Mizuho that are secured by the cash flows from our residual interest in the TEBS financings with Freddie Mac. Our TEBS financing arrangements allocate all underlying bond principal received to senior certificates, such that they have delevered below our target leverage ratios. The secured notes transaction has allowed us to rightsize our leverage on the assets in the TEBS financings.
We entered into 2 total return swaps related to the secured notes, which essentially bifurcates our $103 million in loan proceeds into 2 tranches. The first tranche, currently at $40 million, provides unrestricted cash at 65% of the tranche total, or approximately $25 million. The remaining 35% of proceeds is posted as collateral against our total return swap obligation, which reduces our effective variable interest rate, which is currently at 4.25%.
The second tranche, currently at approximately $63 million, is essentially a 100% collateralized line that allows us to obtain additional liquidity if and when needed. The second tranche has a variable fee, currently at 1% per year.
Through March of 2022, we have the option to reallocate funds from the second tranche to the first tranche and obtain unrestricted cash at 65% of the reallocated amount. As of September 30, 2020, we have received unrestricted cash proceeds totaling approximately $25 million and can obtain additional unrestricted proceeds of approximately $41 million by exercising our reallocation options.
In total, debt financings have a total outstanding principal balance of $670 million as of September 30. Of this amount, approximately 45% is fixed rate debt and 55% is variable rate. Of our $368 million of variable-interest debt financing, approximately $62.5 million is secured by investments that also have variable interest rates, such that we are at least partially hedged against rising interest rates without the need for separate hedging instruments such as interest rate caps or swaps.
During the last few quarters, we have migrated to more variable-rate debt due to lower short-term interest rates and favorable financing terms available on a variable-rate mode through Mizuho.
We regularly monitor our exposure to increases in interest rates through our interest rate sensitivity analysis, which is included on Page 69 of our 10-Q. The analysis shows the impact of our net interest income given various scenarios of changes in market interest rates, and these scenarios assume that there is an immediate rise in interest rates and that we do nothing in response for 12 months. The analysis based on those assumptions shows that an immediate 200-basis point increase in rates that is sustained for a 12-month period will result in a decrease of approximately $3.4 million in our net interest income and CAD. This decrease is approximately $0.055 per BUC over a 12-month period.
Lastly, we regularly provide our net book value per BUC, which as of September 30 was $5.97 per BUC. This is up approximately 4% from our net book value per BUC of $5.75 as of June 30, with the increase primarily due to an increase in the value of our mortgage revenue bond portfolio due to generally lower market interest rates.
At September 30, 2020, the closing market price of our BUCs on the NASDAQ was $4.05 per BUC, which is a discount to our book value of approximately 32%.
With that, we're happy to take questions from the audience.
