yellow Letters right.. his was the only podcast I have ever listened to and well maybe 15 minutes of it.. but I thought now that guy is a closer !!

Scammers may even go as far as creating fake W-2s or other tax documents or advertise fake tax credits to lure in taxpayers to share their sensitive information.Text, Mail and Phone Schemes: Scammers are targeting tax professionals and taxpayers through phone calls, text messages, and even fake AI generated IRS letters.

Caught the flag on the first sentence "given the loan terms verbally" - Pretty much all the "reputable" DSCR Lenders will give out a detailed term sheet / pre-approval letter / LOI (many different names but same thing) outlining terms and approvals early on in the process - the good news is that if you haven't closed yet you can still switch lenders and see if you can secure your original terms - also good news is that the appraisal, while likely ordered by the lender or broker is in your name and your property, so you can likely transfer it to the new lender

What sites do you use and recommend to skiptrace the returned letters to the NTC list?

I would probably try to speak with them face-to-face or on the phone and finish the conversation by telling them you will send them a formal letter shortly with the exact date after you talk with your contractor/partner, etc. 

Therefore, I would recommend sticking with a marketing channel that allows you to reach more people and convert more efficiently.I believed that direct mail could be a good marketing channel for rural areas, where people would appreciate a letter approach more, as they are not bombarded with SMS and calls.Feel free to reach out with any questions!

And get a detailed report on their letter-head. 

I’m in the process of signing an offer letter for a home in the Lake Carolina area of Columbia, SC, listed at $399K.

I would then follow that up with a lease violation letter aka notice to correct.
