To protect myself I don't want tenants knowing my personal address etc. 

Exterior work involved repairing the roof, painting, replacing rotten wood, and installing new light fixtures.Multiple contractors were engaged for the project, with licensed professionals handling electrical, plumbing, and HVAC upgrades.I have compared the comps in this area on Zillow and it’s in the range of 115k to 130k. all else checks out, except that I do not have boots on the ground to verify in-person.  

Have you ever used your real estate or mortgage license for your personal transactions?

The guy messaging me says he will be the primary person of contact and be paying with a credit card for payments.

But you've already paid a truck load of taxes by getting so much for the option.It is possible to sell the property without the deed transferring. 

You must first re-file your taxes for the years you paid via section G, and must re-file using section F.

if you buy a property at market price in a good neighborhood - you will break even or lose money.and in general, if you're serious about this, i'd recommend going to your chosen market in person, probably multiple times, to set up your team. 

spend time there in person.
