Just like VG Jason said, do your own due diligence, trust but verify and run your own business.

I'd offer an easy online solution if they don't want to use their own provider.If a tenant can't afford renters insurance can they afford to replace their clothes, furniture, electronics, stay in a hotel, etc.?

Would it be under the business tax id number which would be brand new (so no history yet) or would it be through me personally through my own credit report/history?

When we owned SF rentals they required $500K of liability on each rent property.I never had to have a general liability policy. 

There are going to be things that come up along the way while owning real estate that sometimes you don't predict.

You can qualify for this by:Having tenants for 7 days or less at a time.Materially participate, typically with the test: You participated in the activity for more than 100 hours during the tax year, and you participated at least as much as any other individual (including individuals who didn’t own any interest in the activity) for the year.If you materially participate, you can offset your non-passive income even if you have W-2 income.

The person then gets called and qualed and so it begins.I am reasonably tech savvy but not as much in this realm (not yet I guess) and nobody end to end owns the process.  

 :) My fiancé owns a home and is moving into my home ... she has owned her home for about 5 years ... should she/does she have to notify her mortgage company that she/we will be renting it?

I own and operate 4 Str and expanding into a few more this year.

That doesn't only mean that you have to be able to close on your own (if you can't find a cash buyer within, let's say, 30 days), but to avoid consistently being forced to close on your own and then marketing a property to potential sellers you should be able to locate a buyer BEFORE you sign the contract with seller.
