It all started with removing some interior walls and changing the floor plan, removing a chimney, adding a bedroom and bathroom, installing patio door to the backyard, and completely renovating every other interior element What was the outcome?

Stop hanging out with your deadbeat buddies who spend all day drinking, talking sports, and otherwise wasting away.

"there are plenty of reasons why a landlord should care who is looking at their property, theft and their own personal safety being the first 2 that spring to mind, followed closely by not wanting to waste their time" These are valid reasons but depend greatly on your market and who is showing the property. 

Quote from @Jaron Walling: @Kane Spangler There's a since of pressure to build or buy RE in your post.

We couldn't help but improve the houses a ton, and part of us feels like it's a 'waste' to just have them rented, as it will put wear and tear on them until we do want to sell

I'm still figuring out how this site works, but I'll be in touch if I hit a wall!

You will be required to get a foundation inspection report on top of an appraisal and you are required to pay for both.That is why I said make sure you do your research because if you pay for an appraisal or foundation inspection report and its not within guide lines you will have just wasted anywhere from $650 to $1000.00 non refundable.  

Sometimes I'll tell them not to fix it (a punch hole in the wall) and I'm charging them for it.

Don't waste a lot of time analyzing.
