Separately from all of that - I recommend reviewing your lease up procedures to improve verification of signing tenants and their agreement and aware of terms and conditions. 

I am seeking recommendations for an app that can integrate with multiple platforms.

Pete Arterburn Hi Pete, are there any areas around or within Sherman that you would recommend? 

BiggerPockets also has a calculator to analyze deals, and I highly recommend you start this as soon as possible, even if you are not ready to buy.

Others have little/no experience and will give you bad advice that takes you down the wrong path.I recommend you focus on educating yourself while saving more money. 

I have never been shy of facing challenges and I truly believe knowledge is power (something my grandfather taught me at a young age)I really want to learn everything there is to learn about realestate and am driven and hungry.Thanks in advance for any suggestions or recommendations.

Additionally, not all transaction types support Locations, meaning you'll have to create journal entries to correct them—requiring a solid understanding of debits and credits, which can be time-consuming and error-prone.Instead, I recommend biting the bullet and upgrading to QuickBooks Online Plus for each entity.
