Again, the BiggerPockets store has some books on this topic, or you can learn about it by watching podcasts, reading blogs, and interacting on the forum.

You just have to handle cleaners and maintenance items. 

Or repair if they renew lease.2) You are NOT required to remove & store them if a tenant has their own appliances. - Just be careful with this one as we once had a tenant store stove/fridge outside in the yard - during the winter -- so they were ruined.

Upgraded kitchens, bathrooms, and other items that hadn't been touched for years What was the outcome?

We use Avail.co to do the background checks, prepare and store leases, and to offer the required renter's insurance policy.Stessa.com does a good enough job acting as a free substitute for Quickbooks.AirBnB and Furnishedfinder.com for listing the space (though I will be trying MiniStays soon). 

For the most part its just health and safety items, which are items we should have remedied anyways.As someone else mentioned, biggest thing to avoid is having the house tagged as vacant which the city will do if it sits empty for too long (handful of months, grass not cut, etc).

The 25K would go towards a rate buy down.As far as accounting for cap ex and maintenance for newly replaced/updated items, I'd still recommend doing it.

Whatever is stored on the shelves will mostly cover it.If it's no longer used, you could remove it completely.

I have one in NE FLorida, he used to own 300 doors, I call him and run my deals by him, I am hoping to get smarter about deals and have him point out items to me SO THAT he can manage them for me, he manages 20 doors now instead of owning.

If I were you (and you meet the items listed above), I would definitely still move forward with licensing since you already have the property.
