You will act professionally, politely, and respectfully, even when a tenant doesn't.

I worked alongside professionals as a "helper" With pretty much no construction experience, they put me on the dirty grunt work, cleaning rat poop, removing the old toilets, scrubbing down baseboards, etc. but as I was doing that, I was watching every single thing they did, and pestered them with tons of questions on how to do things and different techniques.

There are certain issues to consider like the due on sale clause which you can learn more about in the forums on Bigger Pockets but from what I gather is not something to loose sleep over. 

I tried to overcome that objection by explaining that, unlike a LTR, STR's are professionally cleaned almost weekly and during that time they are inspected for damage and if any, repairs are made immediately.

You can use your money however you like, but it will still be taxable.Highly recommend sitting down with a tax professional and figuring out your exact situation.

You did not say if you are going to hire professional installers or do it yourself. 

Its hard to just see a home as a business transaction, but really, it's just a box people sleep in.

An important quality I look for when working with Title Companies is their ability to problem solve, be dependable and responsive and have a polite and professional demeanor when interacting with me or anyone else involved in the transaction.  

You can find local professionals through this site, by going to the "Network" tab and searching "Members."
