I don't know if the police should be involved at this stage....

@Bryce Cutler you can touch on a few issues on a high level, but it would be very inefficient to train at that stage, because we have on average probably over 20 in person applications.

So it depends on a lot of factors.Location, views, sleeping qty/ arrangements, amenities etc I would recommend a house in a non HOA neighborhood.A vacation destination would be my choice over a house on 4th st.

This is not just a product of how frequently the manager can find guests for your Airbnb, but also what price she is able to charge for the nights rented, and perhaps even more importantly, how much of that rental income ultimately flows to you as the owner.If you sign a guaranteed rental contract with the manager, this amount is set.If you use a shared success (or commission) arrangement, the calculations can be trickier.What is the vacation rental manager’s commission rate?

If I was searching online, I may bypass this house for poor photography and no staging.

It seems likes you are knowledgeable and can really help this seller out so why not come to an arrangement where everyone benefits. 

One option might be to find a licensed sub in the area that will take most of the work (wood framing, concrete etc) and try to work out an arrangement with them. 

I am looking for capital growth opportunities at this stage of my investing career.

At this stage I might entertain ordering some new doors with concealed hinges and keep the boxes, soffit and trimwork.

You do not have a business arrangement and for that reason have no control.You will need to wait a couple of years and then hope to convince him to refinance, do not bet on it though.
