Here's the good news: you can ask one of your folks in Burbank to just go to City Building and Safety and ask.  

If you can beat the interest rate with a margin of safety, it's probably worth looking at. 

This is causing quite a stir among the longer term hosts who rent out extra rooms within their homes and feel their safety is being compromised.Our AirBnB propety is actually on our farm but in a separate building, so we are OK with Instant Booking. 

Just out of curiosity what is the best place(s) to live in MA if you were to move there to raise a family(safety,schools,quality of life)?

That way I have a safety net if I need it but I don't have to save it up first.

If the lease is vague check your state laws and post a notice for entry with 24-28 hours (again refer to state laws) to perform a general safety inspection.....say fire and smoke detectors.  

An investor friendly CPA is very important, so kudos to you for prioritizing this.

Being new to all of this I would highly recommend going out and finding 100 vacant properties and then prioritizing them into your top 10-20 based off of free, public records.  

There's no specific requirement for carbon monoxide alarms.While we're on the topic of safety devices, the property code also requires a peephole on every exterior door and a keyless deadbolt or latch on every exterior door.

Then look past the cosmetics...look at durability, safety, foundation, construction, etc.
