Total revenue increased $9.6 million compared with last year's second quarter resulting primarily from a $9.5 million increase in rental revenue, which was due to a $17.7 million write-off in last year's second quarter related to Senior Lifestyle straight-line rent and lease incentive balances.
The increase in revenue was partially offset by reduced rent from senior lifestyle net of rent received from releasing 11 properties in the portfolio defaulted Senior Care lease obligations, abated and deferred rent and a decrease in property tax revenue.
Interest income increased $113000 from the prior year due to the funding of expansion and renovation projects offset by scheduled principal pay downs.
Interest expense decreased by $686000 due to scheduled principal paydowns on our senior unsecured notes lower interest rates and a lower outstanding balance under our line of credit partially offset by lower capitalized interest in 2021.
Property tax expense decreased $311000 compared with last year's second quarter as a result of the timing of certain operators property tax escrow receipts and the payment of related taxes partially offset by completed development projects.
G&A was $757,000 greater than last year due to the timing of accrual for incentive compensation salary increases and restricted stock vesting.

The lease has a five-year term and provides a purchase option for $5.5 million, which is exercisable after the first year of the lease.
Cash rents starting in the second year of the lease is $150,000 increasing to $300,000 in the third year and escalating 2% annually thereafter.
