No, the contract buyer may not simply have you assume that contract, not without written consent of the holder of that installment agreement. :)  

I would ask your attorney if you can without their consent.

Just make sure all original renters are on the lease.Here is a clause in someone else's contract that addresses the sublet part [that I think is good]:  SUBLEASING:  Tenant agrees not to sub-let the premises nor assigns this lease agreement without the express consent of this Owner.  

I want them to sign something stating how many pets they have and that they cannot add any more pets into their home without my written consent)Also, if they have pets, can I require them to have all shots up to date, etc?

I spoke with my attorney and basically he can demand all he wants, but nothing in our agreement states he is to be reimbursed for this work.Now my issue is I fear that he could actually sell the house without my consent, due to the LLC being on title in which either member could sign legal documents, and run off with the money.

Hello, I am the Leasholder on a three bedroom house in Hawaii. i have an agreement with my landlord in writing that i am allowed to sublease to two other people in the house. the landlord has to approve each one, but i am ultimately held responsible for condition of the home and rent paid in full each month. i have signed sub-lease agreements with each of the current tenants. the lease is the same as the one i signed with my landlord, stating that if rent is not paid by the 5th of the month, there will be a $100 late fee. it also states that if rent is not paid, the lease can be terminated early. this is a month to month lease agreement. the exact words are: "tenant's rental agreement may be ended earlier if tenant does not pay the rent and/or comply with this rental agreement. if, after this rental agreement is terminated, tenant stays in the unit without Landlord's written consent, tenant may be a holdover tenant, liable for double the rent and other penalties."

First, under the License Act (and probably MLS rules), you must have the written consent of the owner to advertise the property for sale.

Thanks @Stephen Bell, I just amended my lease to include a maximum allocation of one vehicle per bedroom per unit unless with prior written consent by Landlord.
