I am itching to get started with wholesaling however I have noticed a lot of the REI clubs I look up on Meetup.com do not meet until the end the of the month.

I notice the company now offers a Pro version that monitors your business mileage and can be linked with various apps (such as Concur, Expensify, FreshBooks, SherpaShare, and Xero).To make this work, you'll need to nurture your inner geek (https://www.howtogeek.com/304155/how-to-make-your-car-smarter-with-an-obd-ii-adapter/).

Notice the key words. 

Tenant paid for the entire month, told me yesterday they were moving out today so that’s 18 day notice.

30 day notice to vacate, 5 day eviction notice for nonpayment or 10 day eviction notice for lease violation?

I'd need an agreement with her prior to closing technically and a notice to vacate.The rent is currently under market by about $300 with minor updates.

Keep in mind that this will be factored in when considering your offer.If the tenants are on month to month leases in RI, the seller can terminate their lease with 30 days notice. 

The case was being dragged on in court, all the while we were receiving harassing notices stating service would be terminated and a lien would be placed on our property.

I’ve noticed that from searching on almost every platform I could think of (Zillow, trulia, Craigslist, Redfin, realtor).

With Residential properties you can get conventional Freddie/Fannie financing amortization over 30 years.
