NationStar has a policy of calling you (automated service) if they do not receive your payment by the 7th. Even if you payment is not 'late' until the 16th or 17th; their position is that your payment was due on the 1st of the month and they are calling to find out why you haven't made payment yet.
The automated service will have you call them back - I did and was informed that I would receive these calls EVERY MONTH that payment was not received by the 5th of the month. Due to privacy issues they will not leave a message so you have to call them back.
SInce it is an automated calling service - it is possible that someone without a NationStar mortgage could receive the call. When you call back you have to give them all sorts of info before they will even tell you what the call is about!!!!! So if you know that your payment will be made in a timely manner IGNORE these messages.
I did get a call from this number and it is a valid number and a valid company. Recently they purchased a number of mortgages from other mortgage providers. I called them back and informed them that the auto-call back system is not functional and they would be looking into it.
My mortgage was sold to Nationstar a few years ago and the company definitely has issues with honesty and customer relations. My mortgage is due on the 1st, I have a grace period of 10 days during which no late penalty is assessed. I have automatic pay thru my bank and due to a system glitch one time it did not get to Nstar on the first. They started calling me at home, on cell, and at work DEMANDING immediate payment for which they also wanted me to pay a $40 processing fee. I tried to explain that it would process thru my bank in the next two days and I wasn't going to pay a fee because I really had till the 10th to get it to them. This call came to me at work and the guy became very rude and said I didnt' have a grace period (that is a lie). I told him at that time that I wanted him to post that they are not allowed to call me at work. I am allowed to do this according to the regulations on collections, he then said I wasn't that I would have to send a notarized letter stating such to the corporate office for their review so they could decide if they were going to call me at work again...HUH???
At that point I was so angry I could scream. I still pay my house payment thru my bank but it will NEVER get to them till the last day of the grace period...too bad. If given the choice, never choose Nationstar!
