In California, it is usually standard to have specific language regarding smoke detectors due to recent legislation requiring property owners of any rental to install, maintain and test smoke alarms.Basically, smoke detectors must be operational when a tenancy is created.

I don't discriminate, I screen the animal, require registration - which implies current vaccinations or titer testing, spay/neuter, and I get a sense for the temperament.

@Chris Steven yes, pretty intense guy but wearing out at nearly 52!

The tenant may be testing you to see what they can get away with, and it is far better to start out on solid footing, as opposed to letting things get awkward because the tenant is trying to take advantage of you.

Also, stress test the deals more than you might have a few years ago with different scenarios to see if the deal is still a deal. 

Sounds intense. 

Long story short, it was a 1 year intense project management rehab, then 2 years of churning retail tenants What was the outcome?

I run the numbers and make offers quickly to test for responses like this.

@Ryan Fox With all properties prior to purchase you do inspections and test mechanical. 

You can't really operate on this scale losing all the time - this is not Uber or Amazon, it's a cash flow intensive business.
