Four years ago, Ted bought two rental homes for a total of $460,000. Since then, the homes have been increasing in value at a rate of 3.1% per year. Upkeep on the homes costs Ted $1,430 per year per home, and he rents them out at a monthly rate of $820 each. Both homes have been rented out constantly since Ted bought them. Between revenue gained from renting out the homes and appreciation on the property, which aspect of Ted’s investment has increased in value more, and by how much more has it increased, to the nearest dollar?
