Expected increase in credit score after removal of collections account

Folks 

 

 My credit scores are  681 761 and 703  EQ/ EX and TU.    I had a collections on my report.  The insurance company didn’t pay a  medical bill until 

approximately 1 year had passed (2007)

 

  I called the collections company and they said they would remove it from EQ and TU.

 

Can anyone estimate how much my scores will improve?  I am applying for a mortgage and I think a credit score of 760 + will get me the best rate.

 

Thanks
