Rental Income & Social Security

[David V.]

Questions for you Tax Pros out there.  Will the amount of social security benefits be reduced if an individual receives rental income of let's say 80K a year.  Assumptions:  Social security is taken before full retirement age of 67. 

Although my specific situation is a bit different than most people as I am will be a retiring federal employee at 57 and will receive a social security supplement till age of 62.  Nevertheless, this question applies to all people that receive SS benefits and have rental income.  I just want to make sure that when I retire at 57 and start to receive my SS benefit that I don't loose any my SS income cause I have rental income.  I thought I read somewhere that since rental income is deemed passive income that it will not affect the amount of SS one receives.  Is this true?  If so, can this change if one actively manages their rental properties?   

Many Thanks
