If that's the case in your state, you could just write a simple renewal paragraph on the original lease and get signatures. 

The Secretary shall prescribe regulations with respect to the circumstances under which use of the unit for repairs and annual maintenance will not constitute personal use under this paragraph, except that if the taxpayer is engaged in repair and maintenance on a substantially full time basis for any day, such authority shall not allow the Secretary to treat a dwelling unit as being used for personal use by the taxpayer on such day merely because other individuals who are on the premises on such day are not so engaged."

I tried to do the same thing but could not find developed lots to do it  if you got good bead on some developed lots where you don't have to have hand gun permit to survive, then you got good deal. ignore the next paragraph in that event When renting is your business model, you can pioneer a lot more.
