Some large lenders are offering refinance deals that do not cost any money but those are not a true HARP loan, in order for you to qualify for a HARP your loan has to have been purchased by Fannie Mae or Freddie Mac prior to 5/31/2009, also no mortgage lates in the last 6 months. Where I work 99% of the time an appraisal is not needed, the customers estimate of value is input to the computer and if the system doesn't accept it it will tell you what it thinks the property is worth and you can renter that as a value and almost all of the time it then says no appraisal needed, the point of the program is for those that have lost value in their property to refinance, these are the same as any other refinance and the standard fees are charged which you can include in your new loan amount if your current loan is with Fannie Mae, if it is with Freddie Mac they only allow you 4% or $5000, whichever is less. There are lenders that offer refinancing with no fees that charge a higher rate to cover, everything would be disclosed on the good faith estimate , truth in lending and itemization of amount financed, the rates for harp should be the same as a regular refinance, if not bett, hope that helps
