The first thing we needed was a quick way to streamline applications/onboarding new tenants.

The first neighborhood I would look at is anything next to infrastructure - if it has grocery stores, malls, gas stations.

TAYour ADU application will likely need to be signed by the tenants occupying the property so having a conversation with them is important.

If so, make sure to visit/know of the grocery stores, restaurants, things to do, etc around the area even if just driving by.

Tenant shall be responsible for any property damage caused by failing to maintain utilities or report utility problems in a timely manner.Tenant Utilities: ______________________________________________________________Pass-through Utilities: _________________________________________________________Utilities included with rent: ____________________________________________________Propane: If applicable, Tenant shall return the propane tank level to at least _______% upon termination.

BTW, buying a note from anyone, you can take on all the past liabilities associated with that note from it's application and origination.

What about character references from your tenants application? 

I just subscribed to Pro, but I seem to have 2 different accounts: one for this part of the site and another for the store.

Perform the same task in each app to ensure a fair comparison.Load a property with pictures and details.Market that property.See what your marketing looks like from the public's perspective.Submit a fake application to see how easy the process is.Run a credit/screening report on yourself.Enter a maintenance request, assign a vendor, and attach a fake invoice.Enter charges to the tenant's ledger.Enter recurring charges and automatic late fees.Sign documents electronically.Run owner reports.After testing a few apps, one should clearly stand out.

Again, the BiggerPockets store has some books on this topic, or you can learn about it by watching podcasts, reading blogs, and interacting on the forum.
