Consult an STR expert and hire an inspector for confidence.

FWIW Hostaway doesn't.This felt sketchy to me, but I actually hired someone who had first hand experience with most of the platforms (works in the industry but does some moonlighting) and he supported us giving Hostaway a try.

Literally gave a breath of fresh air.

I would say air on the side of caution.  

Typically what I advise clients is to self manage your first 2-10 units hire your management for 10-100 units and then have the management company scale with you when you get to 100-200 units.

We were desperate to get the house cleaned and ready for tenants and hired our PM with hopes that this would be resolved much quicker.

We just bought an easement from the City Of Rochester and they hired an appraiser to give a third party valuation. 

Hire a PM to manage the current primary once it becomes a rental. 

It seems if you are far away from this property then it might be a good idea to consider hiring the services of an experienced property manager who really could provide ongoing communication during the whole stay.  

I paid him 15k AFTER paying another architect , just because the town insisted I hire him.
