Security deposit = $1,600
Rent for 11 months $1,600*11 = $17,600
In November instead of paying rent to Mary Beth, Carl replaced the water heater. This water heater would have costed Mary Beth $1,100 to purchase and install, but as this was done by Carl, Carl did not pay rent ($1,600). So, for the month of November Mary Beth’s income is $1,100.
Rental income for the last year that is to be reported can be calculated as below: -
($1,600*11)+$1,100+$1,600 = $20,300
Answer: $20,300 to be reported as rental income of the last year.
