They don't care about your property, won't suggest the improvements, and just live of you.I self manage AirBnb in Seattle and hired a remote PM in another property and should admit that if the PM is not local I could do the work and take care of the property much better than a hired PM.

Even if you don't need that rental income, make sure you are using a lender that allows it to be used.And if you dump thousands of dollars into a property to improve the value....but that lender isn't using the ARV...then why even use them?  

Always gotta be studying the market, studying your competitors, and improving your homes to exceed the rapidly increasing competition.
