In connection with certain of our Securitizations (as defined in Note 7), we have retained and purchased certificates totaling $86,617, net of unamortized discounts of $1,320 as of September 30, 2023. These investments in debt securities are classified as held to maturity investments. As of September 30, 2023, we have not recognized any credit losses with respect to these investments in debt securities, and our retained certificates are scheduled to mature over the next three months to four years.

We lease our properties to residents pursuant to leases that generally have an initial contractual term of at least 12 months, provide for monthly payments, and are cancelable by the resident and us under certain conditions specified in the related lease agreements. Rental revenues and other property income and the corresponding rent and other receivables are recorded net of any concessions and bad debt (including actual write-offs, credit reserves, and uncollectible amounts) for all periods presented.

Variable lease payments consist of resident reimbursements for utilities, and various other fees, including late fees and lease termination fees, among others. Variable lease payments are charged based on the terms and conditions included in the resident leases. For the three months ended September 30, 2023 and 2022, rental revenues and other property income includes $41,301 and $35,834 of variable lease payments, respectively. For the nine months ended September 30, 2023 and 2022, rental revenues and other property income includes $113,875 and $102,960 of variable lease payments, respectively.

Future minimum rental revenues and other property income under leases on our single-family residential properties in place as of September 30, 2023 are as follows:

We hold investments in equity securities both with and without a readily determinable fair value. Investments with a readily determinable fair value are measured at fair value, and those without a readily determinable fair value are measured at cost, less any impairment, plus or minus changes resulting from observable price changes for identical or similar investments in the same issuer. As of September 30, 2023 and December 31, 2022, the values of our investments in equity securities are as follows:


	September 30, 2023		December 31, 2022
Investments without a readily determinable fair value	$	54,068	$	21,500
Investments with a readily determinable fair value	1,068		913

In connection with the amended and restated Revolving Facility (see Note 7), we incurred $11,846 of financing costs, which have been deferred as other assets, net on our condensed consolidated balance sheets. We amortize deferred financing costs as interest expense on a straight-line basis over the term of the Revolving Facility and accelerate amortization if debt is retired before the maturity date. As of September 30, 2023 and December 31, 2022, the unamortized balances of these deferred financing costs are $3,702 and $5,850, respectively.
