I also modeled out what the investment might look like if the exit cap rate increased compared to the purchase cap rate.2.

Where I invest, there is quarterly garbage fees LL pays, which get billed back to tenant.Sounds like this model would work for you too.

with the subscription model, i pay less for VRBO bookings than Airbnb.

It’s a terrible thing to do to people and unfortunately I feel the virtual model is a lot to blame for this.

That's a solid model and quite frankly, it is needed in a lot of markets.

That typically happens when the agent gets a lead that's either outside his area of expertise or outside of his geographical coverage area.A mortgage broker can only pay you a referral fee is you sent him a real estate buyer or seller and that mortgage broker, working under his real estate (not mortgage) license completes a purchase or sale with that client. 

And although it may be very nice of you to want to help traveling nurses, that may be a misguided model for your business.

I have had several of my short-term owners go to a self-insure model (i.e. they only get liability insurance on paid for properties) in recent years.

For this topic it is outside of my realm of expertise.

Most people don't, that is not my expertise, I count on my broker to be the expert and to give me what I need that is reasonable.
