To me the value in diversification is that it helps nudge you to look for other opportunities and revenue streams where you might otherwise just be content to stay in your lane and then you'd never find anything new. 

If one tenant stops paying, there goes 25% of your revenue.

Myself I used my own internal funds to prove my model.

Neither VRBO nor Airbnb are vetting guests, either.The best you can do is have some internal controls, such as minimum number of nights.

International rentals are cheaper too to purchase. 

We can all agree rising operating costs dictate revenue needs to offset expenses.

Many of us pay hundreds a year their partner revenue is only increasing and we can't get an APP?  

If so I feel like you should be doing fine on revenue.

You spend so much money before you make a dime of booking revenue.

This allowed us to maximize revenue and occupancy more effectively.Safely Insurance: We also decided to use Safely Insurance, which provides comprehensive coverage for guest damages, liability, and protection beyond what Airbnb or Vrbo offer.
