I have a property manager actually do the showings, but any issues like plumber , electrical is a phone call away.The only challenge is it's a commercial loan, which requires more down, higher rates and shorter terms. 

Properties equipped with the latest technologies and sustainable features often command higher prices and rents, enjoy lower vacancy rates, and have reduced operating costs.

When chatting with an insurance representative, inquire about policy limits, deductibles, covered events, guest screening discounts, and the claims procedure.

Does anyone know how true this is and if mortgage rates will keep going up? 

If so you definitely  need one.If you or most all of your competition doesn't have one then it's not necessary but it may help set you apart from the competition if you need to increase your occupancy or nightly rate.

The only con is the higher interest rate. 

The issue here is in order to increase rents at reasonable rates to cashflow well you need to not just do cosmetic changes they require you to do extensive plumbing and electrical to be able to increase the rents. 

If it is a normal 70/30 leveraged property, you may end up subject to tax on 70% of your returns anyways - so cost benefit, is that 30% tax free portion worth the high tax rates paid and additional filing fees to get tax free treatment on the 30%?

There's a lot of moving parts here but it sounds to me that you owe them at most the original $150k + a conservative 8-10% interest per year (well above market rate).

Please elaborate on why each is essential and how they contribute to a company's overall performance and reliability.Similarly, provide a list of red flags or negative traits that indicate a subpar or potentially problematic property management company, with explanations on how these might negatively impact my real estate operations.Create a scoring or rating system that I can use to objectively evaluate and compare each property management company based on the traits and skills identified earlier.
