Our price per contract is about $4,500 but will change depending on your marketing channel and market.  

I would say the MOST important things are 1) communication with your guests and getting good reviews, along with 2) having a vetted team (handyman, cleaners, etc.). and 3) document EVERYTHING regarding issues and Air BnB will take care of you (without documentation you're out of luck).

I believe in keeping very strong communication with my tenants.  

Plus you can still communicate with them and choose who you want.  

If there is a problem, the Architect/Designer would be in communication. 

Go in with your guns a blazing, just make sure that if they aren't communicating with you and your due diligence period is nearing to pull out of the contract.

However, by staying on top of project management and maintaining clear communication with contractors, we overcame these challenges.

It is best feel out your broker/loan officer to see if their knowledgeable, experienced, and can communicate with you when needed most. 

Communicate with the lenders to let them know I'm the new Deed holder.What other considerations should I take? 

You have to make sure they do quality work and communicate well, otherwise you're held hostage.
