i got several calls from this number n they never answer when i call back it says all circuts are busy..

The caller ID said digital risk.  The woman was timewasting asking me for private information on a former tenant, saying she wanted to verify a rental amount.  She asked for my fax number.  I gave it to her, there was some confusion as to who she was trying to verify.  I asked who she worked for and what she needed this information for, she said it was for file verification, talking to me as though I am an idiot, which inscensed me.  I then told her to fax it and that'd I'd do my best to help her when I have time.
She then told me I don't need to be rude, to which I replied, I am a property manager for 80 units, you aren't my tenant and you are asking me for more of my time, to which I have already wasted 5 minutes.  She then called back from a private number and told me I don't know who I am talking to, that she's the wife of the president and I have been warned.  If she reads this, can I just say [***] off you scam artist time wasting [***].

Same thing happened to me.  Scammers.  The company name from the caller ID is Digital Risk, I looked up a website which looks legit, called the number and it comes up with a party line.

I know that number and it is definitely them.    They are a company who reviews closed mortgage loan files and the information for legitimacy.    The are a real company- you can google them to confirm.   The processor just needed to get the information on the prior tenant re-verified for the investor.

This number appears on your caller ID, becuase it is a number assigned for outbound calls. However, the company can be reached at their main number which is 407-215-2900.
The business is a legitimate business, their job is simply to re-verify specific data that was supplied during the initial financing.
To the Property Manager, your posting is very upsetting because you should not have been treated in this manner and just to clarify Digital Risk is limited on how much time a review can take so although it may be an inconvenience for you to get back to them quickly. They are limited on time.
And just for the records, Digital Risk reviews files for fraud, fraud could have taken place by anyone involved in the file from the borrower, lender, title, appraisal, employers, banks, and even property managers.

Hope this clears any misconception as to the legitimacy of Digital Risk
