(I work with some challenging populations and the extra effort has paid off in these situations.) 

Written policies are necessary when you add employees to aid with training or enforcement of standards.I would focus on adding doors to your management company.

We added features to our Airbnb in Lake Tahoe and surpassed Airdna's estimate within 6 months.

Adding $125 - $166 per door boosting overall property value.

I’ll admit the fear of failure and unknown holds me back regardless of goes many articles or reports I read or deals I look at.during this search hundreds and hundreds of ads come through for training/mentorship style groups.

Quote from @Mary Peale: May I ask which amenities you added that you believe contributed to a revenue boost? 

The reality is the opposite - if it's not in writing then the PMC doesn't have to provide the service or can charge extra for it!

Not to mention, you're adding an appreciating asset to your portfolio. 

It may sound nice to pay a 6% management fee but the extra fees can add up to be more than the other company that charges 10% with no additional fees.

Should I take extra steps to verify their identity and legitimacy?
