mortgage loan commitment question

[Michael Frish]

A question for those who are connected with a mortgage (working as a broker or with a broker) or have received a mortgage:

How legitimate is the broker's claim (clauses from the mortgage loan commitment):

1" This approval is based upon your current liabilities. You should not apply for or enter into any new credit obligations (i.e. car loan, car lease, credit card, etc.) prior to your loan closing."

2. " Improvements are to be built in a good and workman-like manner In strict accordance with plans and specifications fumished Lender and in compliance with applicable building codes. After completion, said improvements shall be approved by a representative of Lender and an occupancy permit issued by local municipality. Any changes, whether they be additions, deletions, or alterations, of the plans and specifications, must be approved in writing by Lender in order that this loan commitment remain in effect"

I'll pay 20% down payment and have a very good credit history, no debt and a high income. Particularly worried about the first point ... Does it mean that having signed an agreement with these points, I lose the opportunity (mortgage for 30 years) to take a new car, buy additional real estate, etc.?
