I'm just speaking from a new host standpoint with the interface offered from both platforms, options & booking results, AirBNB is much superior in my opinion. 

These platforms typically have billing policies where you pay a per unit fee per month to the software and you get regular updates and support each month.There are a number of low-cost platforms available that are able to offer you a lower price by passing along some of the costs to your tenants (payment processing fees, applications, tenant screening, etc).

Follow new listings closely and be definitive in scheduling tours and making offers.

That has nothing to do with us but we still offered to help you.

Offer to help with lead generation, driving for dollars, cold calling, or even administrative tasks.

Rentals generate passive income, so an S-Corp offers no added tax benefit.

Look at their finishes and what they offer guests, use that as your baseline, then improve upon it.

Offering a rent-free period helps the seller stabilize, but what happens if they still can't afford rent when the time comes?

The builder offerred $15,000 credit to be applied, however you wished EXCEPT can not be used for price reduction. 

@Johnny Lynum we did offer them an aggressive cash for keys amount to get them out as soon as possible.
