Same-Store Communities
Our Same-Store Community properties, those acquired, developed, and stabilized prior to April 1, 2019 (for the quarter-to-date comparison) and January 1, 2019 (for the year-to-date comparison) and held on June 30, 2020, consisted of 39,020 and 37,910 apartment homes and provided 80.3% and 77.6% of our total NOI for the three and six months ended June 30, 2020, respectively.
Three Months Ended June 30, 2020 vs. Three Months Ended June 30, 2019
NOI for our Same-Store Community properties decreased 4.5%, or $7.9 million, for the three months ended June 30, 2020 compared to the same period in 2019. The decrease in property NOI was attributable to a 2.2%, or $5.5 million, decrease in property rental income and a 3.6%, or $2.5 million, increase in operating expenses. The decrease in property rental income was primarily driven by a $4.1 million increase in our reserve on multifamily tenant lease receivables, an increase of $1.6 million in rent concessions and a decrease of 3.4%, or $0.9 million, in reimbursement and ancillary and fee income, partially offset by a 0.8%, or $1.7 million, increase in rental rates. Physical occupancy decreased by 0.6% to 96.3% and total monthly income per occupied home decreased 4.4% to $2,247.
The increase in operating expenses was primarily driven by an 8.1%, or $2.3 million, increase in real estate taxes, which was primarily due to higher assessed valuations, and a 7.8%, or $0.8 million, increase in repair and maintenance expense due to the increased use of third party vendors, partially offset by a 6.2%, or $0.9 million, decrease in personnel expense as a result of fewer employees.
The operating margin (property net operating income divided by property rental income) was 70.5% and 72.1% for the three months ended June 30, 2020 and 2019, respectively.
