If you take that same time and energy to setup showings, list it for sale, have friends and family spend their time coming out and masking up to cough and act interested, the man hours add up.

There's nothing wrong with that, it's just another layer of information to navigate. 

Get a decent property manager that handles the maintenance/tenants etc... as a separate layer of protection against lawsuits.Stephanie

You have a factor of cap rate compression and increasing income that adds layers to the cash on cash metric.Apartments will vary based on location for larger buildings.

If you're a single owner, and you are about to buy your first property, I find an LLC to be a layer that just isn't necessary. 

Of course, Anderson will be glad to sell you another LLC when you get a property; with a Series-LLC, you just issue an internal document and you have a new child Series-LLC to use.I think Wyoming LLC has an additional layer of anonymity/privacy - Wyoming does not require the manager nor the members of a Wyoming LLC to be listed on a public database.

All need to be evaluated at least 3 layers deep each. 

Many states will allow up to 2 layers only per roof. 

This is a country (I've been there) that has a perpetual 365 day smog layer that makes LA's look like a bad cauliflower fart.

The outermost layer is an umbrella policy, followed by using an entity, followed by landlord policies etc.
