Linq If Statement

I am trying to run a query using Linq, but before the where clause I wanted to specify the If condition but I am not getting proper syntax(may be) or is it not possible?
I have searched a lot but they use if and else before query, but I want If within query.
Is it possible like:

var q = (from mortgageapplication in context.MortgageApplications
         if(mortgageapplication.purpose of loan==7)
         {
              where mortgageapplication.MortgageActive == true && mortgageapplication.MortgageCoordinator==ID
         }

I am just trying but let me know if we can place if before where?

Answer 1

This query would be logically equivalent:

var loanPurpose = 7;
var coordinatorId = ...;
var query =
    from app in context.MortgageApplications
    where app.PurposeOfLoan != loanPurpose
        || (app.MortgageActive && app.MortgageCoordinator == coordinatorId)
    select application;

The logic goes as follows, you only want to check if it is active and by the given coordinator. Otherwise get any application.
