Disclaimer: I'm not an attorney, so it is possible that my understanding is not legally accurate.

You would also layout whether each of you would require the consent of the other to sell your share to a third party {or whether that would be permitted at all}; whether each party has first rights if the other decided to sell; and the terms under which one "partner" could sell to the other.  

Is this legal in Baltimore county?  

When you are in escrow on the deal you will want to hire a 3rd party inspector to check things out before closing.As for a handyman, contractor & lawyer your Property Management company should already have that all in place so none of that will be necessary for you.

I would also seek legal counsel in the same area where your property is to find out how you can minimize your fines.

I'm still pretty new to the party so I couldn't compare it to other markets.

However, as a licensed agent, I legally can only do the deal as myself, an individual, not acting as an agent to anyone; self-representing.  

In either case for what I'm doing, I need an architect for the site plan for the change of use and a land use attorney for the legal aspects and complying with the notifications to the surrounding property owners. 

You would usually just flip the contract to another party for a fee.All you would need in terms of documentation is the agreement of sale that would to contain the words "and/or assigns" which would go after your name (since you're putting it under contract).When you find this person to flip it to, you'd add an addendum stating who the new buyer is.
