For me, they were not that bad, their customer service is inconsistent and there is no stable way to pay online unless you do it through western union.  For a financing company to not have an online portal is pretty ridiculous, but at the time my credit was in pretty bad shape so I am grateful they said yes.    All in all, as long as you pay on time, you shouldnt have any issues with them. They processed my title pretty fast once I had them paid off.

Refinancing next week after only 1/2 a year. I sent in a mortgage payment early with correct month's payment slip and July payment written on the check. They applied the funds to June (to extra principal). I called to tell them that I did the same w/my other mortgage companies and EVERYONE else applied the early payment to the correct month. Now the paperwork is a mess and I have to go through the 6 months of payments to see if they correctly applied funds. Worst of all, the woman rep. was the RUDEST person ever. I think they do this on purpose because she seemed a bit too ready with her responses. Today I got a notice in the mail stating that I owe July payment and August with over $100 in late fees.. ALL FOR PAYING EARLY AS I WAS IN EUROPE FOR # WEEKS. Punished for their inability to read and paying on time!

PennyMac is about to foreclose on my home.  I tried getting a lower payment, couldn't.  Ultimately I had to choose, medical care or home.  I chose medical care.  Now I am getting well but faced with "how to find a home, rent or otherwise, with bad credit and pets.  PennyMac did try to help me.  The laws and investers controll a lot of the actions of all lenders.  Just because they cant help you in your time of need, does not mean they did not care.  They listen, searched for options, and worked hard on my behalf.  For that I give them a 4.  I took 1 star away because they made an error on my streamline refinance that caused my house payment to increase by $900 a month and left me without options.  Their error, I paid the price.  

We have bought and sold 8 houses in 30+ years and this was the best experience we have ever had.  They were quick and efficient with the process, and kept us updated every step of the way and actually in the end saved us money on our loan and monthly payment.  We would use them again.
