The lender that only makes 6% is ok because of the safety.

Do you only accept tenants if you “think” they can pay their bills and just as an extra safety precaution you get a co-signer?

Also you will hopefully have the safety net of health insurance provided by your job.- Work, save, INVEST!

I am just letting you know, we will be extra careful going down the stairs for our own safety, but you never know when something could happen.

Just say that your insurance carrier wants you to do a safety inspection and to provide updated pics of the interior since it's been a few years. 

In need of major repairs and is not suitable for living due to some fixing that are safety issues but has potential?

@Jim GoebelThank you very much for sharing your perspective, your thoughts are very useful for me, I have a little break from managing everyday issues, so I was thinking to make some decisions on who is responsible for  working fire detectors, what company to hire to check detectors and other safety issues, I am going to sign an addendum/reminder that people would not use basements as a bedroom if there are no 2 exits. 

I'm not going to name specific markets but there are a LOT of cities throughout the US within geographic boundaries that are often very close to each other, that have extreme disparities in income, educational attainment, safety, etc. 

We couldn’t have holes in walls or floors, had to have running water, and a few other “safety and security” issues that I can’t recall right now.  

Unless there is a safety issue, I wouldn't touch the bathroom until the unit is vacant.
