I will say a few things though: Pros:My experience with them improved over the 5 years each year as they added more features, services and personnelThere 10% fee (10% of nightly rates and cleaning fees) is still reasonable for what they do if you don't want to worry about setting up and managing listings, professional photos, payments, guest inquiries, calendars, etc.They basically handle everything up until check in, they then set you up with one of their 'partners' in the area for the rest or you self-manage everything after check-in (I opted for the latter)Their staff is friendly and their owner portal is a really nice feature to go in and look at your portfolio of homes with them in a single space. 

I'm excited to dive into the world of single-family home flips, with a budget of up to $150k per property.

They charge 8% if you don't. 

Is this different than a house hack (where you charge roommates rent)?

We charge a $50 late fee to motivate the tenant to pay on time.

I would never form an entity with them when I can do it online with a firm that charges a fraction of what they charge).

If they are good tenants, they don't worry about it for a single second because they expect to follow the rules, and they rest easy at night knowing their neighbors will have to do the same.VERY impressive! 

@William MillerIf you have a full-time W2 job and are single, none of what you listed is going to reduce your current taxes.

Next time just charge market rent and gift them $6,000 at the end of the year, every year, like Santa.

You can see these charges added into your payoff demand by line item.
