Does anyone have an online link where we could all do this?  

Subscribe to the local paper online, start to follow the real estate market locally.

There is an online calculator that tells you how much interest you have to give them (no it doesn't matter if you actually made that amount of interest or not on the deposit).

I've seen a lot of bad excel templates online...

I have looked around online, but haven't had any luck yet, i have local real estate agent there, but they are not expertised on those distressed properties.  

If you know of any online forums or organizations where I can learn from others and expand my network and knowledge on wholesaling or getting my first deal, I’d really appreciate any recommendations Thanks in advance for your help!

They’re doing this across all online platforms. 

is there a way for me to create an online STR guestbook for free? 

To managed it a bit easier (when you grow to more than a dozen), it'll be better to have one online login and manage all 'child' accounts.

You should be able to search (if your county has online records) for your tenant’s name and/or all previous addresses listed on the tenant’s credit report.
