So the above, is directly in response to your question/strategy BUT, I would certainly consider NOT SELLING THE LOT NEXT DOOR... especially since you said you're seeking 'additional cash-flow' -- if you sell, it won't be recurring cash-flow instead it will be a one-time infusion of cash into your bank account and then its done AND you won't have much control on what happens next door aside from what restrictions you have placed in the deed... why not instead of selling consider... offering it as a 'ground lease' whereas, the person seeking the lot is allowed to build on the lot but then will pay you rent for the use of the land... this would be similar to some commercial agreements or even mobile homes where the tenant owns the structure but you own the land on which it sits on.. it's also quite similar to how McDonalds and some other franchise businesses operate it's how they are able to ensure that the properties being built are built and operated in accordance with their vision, if a tenant does not build it or operate it 'correctly' then the Landlord will have leverage in ensuring that it is rectfied... because after all you do still own the land and may terminate lease if the terms are violated.
