the information you provided doesn't make sense. you say rental income $7,000 real estate taxes $700. net $6,300. what about depreciation on the real estate? what about other expenses. also rental income is not earned income so you should receive $0 EITC based on that being your only income.
earned income includes wages, net earnings from self employment (schedule c, f or se income from a partnership), and limited other sources.
there should be a worksheet in your return which would show the calculation
we can not see your return.
