You just have to close the sale of your old property before you take title to the new properties. 

1) Research Zoning of similar property2) Do search with same zoning criteria with propertyradar or have title company give you a list.3) Possibly filter by satellite photos to eliminate undesirable topography.

(There’s no way to transfer title that can legally prohibit enforcement of due on sale, except transfer to the owners REVOCABLE trust or transfer to children upon death).  

But normally people with a title like yours are referencing low income housing which there are many options already.  

Title insurance, if paid by Buyer6. 

The specialist I recommend you have is an attorney to properly draft the documents and a title company to facilitate the deal.

Need a lender who understands that clean title will only occur on the day of closing.

I have been working with the title company who wants me to changes this to purchase the property and put my name as the manager. 

Title report, confirm utilities and zoning etc. 

As mentioned have an attorney or title company draft the note and mortgage.
