@David S.Very limited info, but here are my thoughts...You're right about how much supply is coming online in Nashville.

First, I need to learn how to protect myself and my current tenant against some of the issues I've seen online where renters will stay past the date they're supposed to leave.

Do not use a program for your computer when you can use an online rental manager for nothing.

The way it's portrayed online brings too many unethical people into the business, giving the good ones a bad reputation.

Needless to say, I explored further by pulling up & printing all information and pics online pertaining to this property & even got in touch with the real estate agent who sold my friend this house to find out some info about the Granny unit I live in & if it was truly built without a permit.

I have found them online but you might have to search as they're usually accessible only to realtors.

Go to Etsy and search for "rental property tracker," and you will find hundreds of nice spreadsheets to track 10-20 rentals, usually for under $10.Software has extremely helpful features like online payments, marketing syndication (click a button, and your property is advertised on multiple sites), electronic document review/signing, maintenance tracking, and owner reports.

Eventually, and regretfully, I signed up for QuickBooks Online.

The lock won’t show online for remote lock or the Schlage app 

Look the employer up online, then call the public number.
