small, and has an allocation based on fair value of real estate properties as determined by our NAV calculation of 23.0% office, 33.6% retail which is primarily grocery-anchored, 29.4% industrial, and 14.0% residential.
We believe that our cash on-hand, anticipated net offering proceeds, proceeds from our line of credit, and other financing and disposition activities should be sufficient to meet our anticipated future acquisition, operating, debt service, distribution and redemption requirements.
Cash Flows. The following table summarizes our cash flows for the following periods:
| | | | | | | | | | |
| | For the Nine Months Ended September 30, | | | | |
(in thousands) | | 2021 | | 2020 | | $ Change | |
Total cash provided by (used in): | | | | | | | | | | |
Operating activities | | $ | 38,750 | | $ | 28,847 | | $ | 9,903 | |
Investing activities | | | (226,175) | | | (236,786) | | | 10,611 | |
Financing activities | | | 188,687 | | | 126,597 | | | 62,090 | |
Net increase (decrease) in cash, cash equivalents and restricted cash | | $ | 1,262 | | $ | (81,342) | | $ | 82,604 | |
Net cash provided by operating activities increased by approximately $9.9 million for the nine months ended September 30, 2021, compared to the same period in 2020, primarily due to net acquisition activity, which was partially offset by an increase in interest expense due to our increasing rent obligations resulting from our DST Program and an increase in performance-based fees paid to the Advisor in 2021.
Net cash used in investing activities decreased by approximately $10.6 million for the nine months ended September 30, 2021, compared to the same period in 2020, primarily due to (i) an increase in net disposition proceeds of $138.6 million received in 2021 related to the sale of one retail property, one industrial property, and two office properties, as compared to the sale of one retail outparcel during the corresponding period in 2020; (ii) cash paid to acquire a debt-related investment during 2020 of $45.5 million; and (iii) $5.9 million of lower capital expenditure activity. These drivers were partially offset by a $184.4 million increase in acquisition activity during the nine months ended September 30, 2021, as compared to the same period in 2020.
Net cash provided by financing activities increased by approximately $62.1 million for the nine months ended September 30, 2021, compared to the same period in 2020, primarily due to an increase in net offering activity from our DST Program and public offering of $66.9 million and a decrease of redemptions of $38.7 million. These drivers were partially offset by a $45.0 million net increase in repayments of the line of credit and mortgage notes during the nine months ended September 30, 2021, compared to the same period in 2020.
Capital Resources and Uses of Liquidity
In addition to our cash and cash equivalents balances available, our capital resources and uses of liquidity are as follows:
Line of Credit and Term Loans.

As of that date, we had: (i) $85.0 million outstanding under our line of credit; and (ii) $525.0 million outstanding under our term loans. The weighted-average effective interest rate across all of our unsecured borrowings is 3.02%, which includes the effect of the interest rate swap agreements related to $500.0 million in borrowings under our term loans.
The unused and available portions under our line of credit were $365.0 million and $252.6 million, respectively. Our $450.0 million line of credit matures in January 2023, and may be extended pursuant to two six-month extension options, subject to certain conditions, including the payment of extension fees. Our $325.0 million term loan matures in January 2024, with no extension option available. Our $200.0 million term loan matures in February 2022, and may be extended pursuant to two one-year extension options, subject to certain conditions, including the payment of an extension fee. Our line of credit borrowings are available for general corporate purposes, including but not limited to the refinancing of other debt, payment of redemptions, acquisition and operation of permitted investments.

As a result, the Federal Reserve Board and the Federal Reserve Bank of New York organized the Alternative Reference Rates Committee (“ARRC”), which identified the Secured Overnight Financing Rate (“SOFR”)
