First you should get all the money necessary to pay for your home construction and pay Tom Nook without getting inside your tent after your saved for the first time.
In the next day, pay the first loan and don't get inside the house during the same day,
A day after you'll be notified about Tortimer being waiting you at the pier and now you can enter home without being interrupted.
If you want to add some stuff to your tent house and avoid Isabelle's visit, then you can open the ticket gate and Isabelle won't get inside since she is waiting for the visitors.
