If so, you can give the notice before the end of Nov and make it effective on February 1st, 2022.I always recommend giving proper advance notice and raising the rent on the Lease anniversary every year.

Generally speaking, I would post the proper notices according to state law and then start the clock ticking until you can officially treat it as abandoned. 

I’ve read a couple books that discuss the importance of this, is there any other way you’d recommend to learn how to properly assess and value properties?

I’m pretty new, so I’d weight some of the advise from some of the others more heavily.  

Needless to say, the new lease came with a rat clause that they could move them into an aquarium as proper pets or they had to go.

Not only do you want to properly outfit the places, but you are going to want to do a thorough risk management assessment for each place to mitigate the risk of accidents.  

If the foreclosure was done properly that should wipe out the lis pendens.

And, as a business decision, you likely want those businesses to stand or fall on their own; you do not want your rental business to carry the financial weight of your fix & flip business (at least not indefinitely).

Would it be wise to continue with my original plans and run the high risk of having bad tenants in my first landlording experience or should I sell then use  what I've learned to properly analyze and purchase my second property?

@John BoychukYou are right that we still have to give the 90 days notice for someone who's been there for 2+ years (we currently have one tenant to whom we gave notice who's supposed to leave by end of february).Correct me If I'm wrong but when you have an annual lease, you can't break it mid-lease, even with proper notice unlike month to month.
