Account Closed , careful.

I do have to tell you to be careful of certain meet-ups as they can be solely used for attracting new investors who aren't entirely knowledgeable about investing and they can get taken advantage of (I know multiple individuals that have).

You may not care about selling them, which is fine, but just know that going in. 

Apparently the seller had to replace the floors a few years ago due to issues with the joists but didn’t take care of the bedroom.

It's hard to find deals right now, but if you're the bank (cash purchase) or you don't care if your returns top 7 or 8% (institutional buyers) then you're going to clean up nicely because competition has greatly slowed.  

We received a small note like this: -Paint and small repairs: $ 900-Other supplies: $300-Rent ; $100 We really took care of the apartment, removing all the shelves, plug all the holes and did the cleaning myself.

Ultimately it may be in your best interest to take care of it and may be required by law depending on the state.Rats don't squeeze in under a door, not a normal door at least, so I would first make sure that all outside cracks, crevices and holes are filled up, especially in a crawl space to prevent anymore from getting in.Then, again it really depends on the state laws, but after my due diligence is done sealing up the up the outside and inside of any places a rat could get in I would think about telling the tenant that they can buy rat traps or whatever they want to use to get rid of what's is inside and I will reimburse them the cost with a recipe, I would only do this if I felt comfortable with local laws otherwise I would just hire a pest control person to take care of it.

Who is doing lawn care/snow removal?

You can try to screen more carefully, but you will still have tenant who cause you grief.

You might feel that they deserve some interest on the loan but you might not be able to deduct it.If you do not care about it's ability to make money or an increase in value over any time.
