Typical on the Internet though.

Please educate yourself, and not just from an internet forum. 

An entity that operates hundreds or thousands of apartment units has far less concentration risk than an owner of a few rental homes, whose tenants may all be impacted by COVID-19.Do you think Portland’s ten-year trend of positive economic growth for landlords will continue, or will it flatten out, possibly even declining in the wake of COVID-19?

To gain investor confidence, ensure the investment property numbers are real, use the most common contract forms in your state (versus a 2 or 3-page) internet/guru contract form) with appropriate addenda, or an attorney-drafted form and attorney-drafted assignment agreement.

Best bet is likely (not absolute - everyone's situation is different) is to look at a national lender or broker that has options in lots of states - its a great development versus 20 odd years ago, with technology, internet, places like this - can have access to many more options than before (local broker or lender thats it)

My acknowledgement of investors seeming happy was based on internet discovery. 

Also do not take documents off the internet, get an attorney to draft documents for you and also always close with a title company. 

Can any of you make some recommendations on how we can install cameras without possibly having to use an internet network?

There are a lot of shiny internet companies touting their HELOC, but you will do better with a local bank every time.

In February 2020, the tenants in a unit on a lot she lives on vacated per a 60-day notice, after my mom discovered they've been subletting the house to internet strangers without her consent, violating the lease agreement.
