I own a few rentals near the Memphis international airport.

JBF Financial Services LLC DBA Finance International Group is a boutique mortgage brokerage that only does business in Florida.

I’m currently exploring real estate investment opportunities in Canada as an international investor.

If the software is not simplifying your life or making you more accurate, you shouldn't use it.Software does have 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.

As with any electronic item they can fail, so I keep an extra new lock on site at each property for maintenance to install if needed. 

If the electronic lock fails, you provide the tenant with the code so they can access the key.

Nice to meet you (electronically).Currently renting a single-family home in a very expensive coastal Southern California city.

As real estate professionals, we know that international transactions come with unique challenges-different laws, cultural expectations, financing hurdles, and currency exchange factors.

However, you forgot/didn't mention the Costa del Sol, which, from an international real estate point of view (the topic here), is what matters.

There is also the International Property Maintenance Code.
