I was watching a video that mentioned one of the mistakes we noobs make is buying illegal multis unknowingly.

I didn’t read it but listened to it on a site that people watch a lot of videos :)

I had the intent on supplementing my direct marketing by sending video text messages to prospects.

Thanks to running into some of the videos that Brandon Turner had placed on YouTube I have found this wonderful site and wealth of resources. 

Perfect , you are one good combo.Nice to know about HD vs Lowes , its fascinating how each chain operates completely differently .Great info .By the way , I just looked up window resizing and apparently , reducing the size was much easier than enlarging, there were couple of good videos on youtube

Next I will advise you to educate yourself here by listening to podcast and youtube videos made bt Biggerpockets contributors, Then I will meet up with Real estate investing group in your city; if one do not exist start one.

We have a guest requesting a copy of the front door video surveillance footage? 

I did watch this video, and it seemed like I would be financing the property mostly through traditional products. 

Please go listen to the podcasts, watch YouTube videos, & read books You will feel 100 times more comfortable then you are now 

From a legal standpoint, jurisdictions vary widely in their laws - search for the thread about NJ and audio/video cameras last month for a taste - so I won't get into the weeds whether the OP is in a "one party" or "two party" state with regards to surveillance.By her own admission, the OP is already suffering the fallout from the other tenant from her overstepping bounds and making them uncomfortable in their own home.
