@Houston Pitts GREAT QUESTION!
As a hard money lender - I have people blindly send me all of their personal information without even having a conversation first - it blows me away. Our company has been lending for 8 years and are very well known in our area, but it doesn't excuse how reckless people are with their information. I have closed a lot of loans without even meeting the borrower. So you are right to ask the questions.
I would provide the information they require on a PFS or application - without providing SSN or taxes until you have a deal and approval that feels right
Ask for referrals of other clients
Try to work with lenders in your area - not someone 6 states away
Ask around BP or local meetings about lenders
I would rather pay a little more for the money and know the lender is legit than to look likea fool at the closing table
Not only is it important to know your information is safe, but you also want to know the money will be there when you need it. There is a lot to navigate, but you absolutely thinking about it the right way.
