If so, we planned on having a discussion to work something out with the tenant and would only like to involve our lawyers if absolutely necessary.

That way a bank is not involved or only involved partially. 

They have not been involved at all.

If just getting to help you as an investor it usually isn't worth it in my opinion since you are held to a higher standard and the fees involved with getting/maintaining your license.

I can try if I can find a source to finance the entire project, including the fund to purchase the corner as well. the problem here is the discussion with the city will be very preliminary, as it is the best I can do without having the actual ownerships of all properties involved. 

All business involves risk.

Several states have laws on the books mandating the presence of an attorney or other types of involvement at real estate closings, but you can use a title company to close your transaction.I'd suggest you use an agent who knows the area well and has a good marketing plan for you property.

This is a form of rental arbitrage and is talked about here from time to time but it is usually where the renter is putting it on air b&b where the spread will be larger than with long term but there is also more work involved.  

The cost of moving mobile homes also varies by location (based upon the local rules regarding whether or not a licensed electrician/plumber have to be involved).

Once the actual eviction has been granted (through the court system) law enforcement becomes involved to make sure the process goes smoothly.Gail
