It also sometimes comes into play when I am acquiring an MLS property.

My town is land locked with not a lot of options for building, but the area continues to grow. 

I'm not in it for the "get rich quick" schtick, this is a long term play, hence starting young at 22.

You could argue the the activity is not regular and continuous enough in order to be considered a trade or business, so it would be a capital gain.

Selling this house will be difficult in the future, so continue on as a rental.

For example, if you are going to focus on Google Adwords, you have ads and are continually running optimization tests, you have all keywords setup (including negative keywords!) 

The market rent has increased over $100/month but we raise our continued tenants less than that but the value adds have had rent increase so substantial that overall our rents are up over $100/month per unit for each of the last 5 years. 

I have inherited tenant which I will continue untill lease expires.

There is a wealth of knowledge to be gained and connections to be made on the BP forums stay engage and continue learning.

Feel free to ask questions and continue educating yourself while working on your BRRR strategy.Good luck!
