If you have an agreement in principle and decide to make a full application to this lender, you must provide more detailed personal information. The lender is not required to lend you the full amount described in the AIP. Contractors must therefore be vigilant when reaching an agreement in principle. Make sure that the body issuing your certificate includes the payment structures of limited liability companies. If they don`t, stop! Your “decision” could do more harm than good to your search for a mortgage. An AIP does not guarantee your loan because it is not a mortgage offer. And if the lender finds something you haven`t mentioned yet, that has a negative impact on your ability to get a mortgage, they might change their mind about whether they`ll give you loans, how much they`d lend, and what the interest rate will be. . . .
