Don't keep it on the exchange or any web-based monitoring(cloud storage, keys on excel on cloud, crypto storage online). 

@Ron Amshalom not aware of any that aren't cloud-based now.Not really sure what you're asking for?

In our company we basically use the cloud based expense reporting software that takes care of the accounts, invoicing and billing in a precised and significant manner.

I keep hearing great things about Tenant Cloud.

I had never heard of a QAT until a buyer couldn't secure a bank loan as the title was clouded and so my journey began.After giving my attorney 3k to start the process it was 6 months before I heard from him. 

The abstract also serves as a cloud on title which will prevent the tenant from selling or purchasing property (in-state), unless your judgment is satisfied.

Depending on the bookkeeper, that first acquisition or refi may recoup your annual cost and open up additional growth. 100% do recommend cloud accounting software like Quickbooks Online, 100% do not recommend hodgepodging a system together yourself.

Commonly referred to as "the cloud," data centers are hubs for computer processing power used by many companies and industries.

There isnt as much value in someone's services who is just a connector and doc-chaser, compared to someone who provides insight, guidance, experience, and negotiating power.

Recording under those circumstances would cloud the title of a property in pre-foreclosure, not a worthwhile action and very dangerous.
