There is no way around it, you have violated the lease and his legal rights by bringing an animal into his property without his consent.

The due on sale is under the note, but sence you have no interest rate risk as a lender, I suggest you add that you have a due on sale without written consent and modification of the note and deed of trust and that consent may be denied at the sole option of the holder.This stems from the fact that a seller financed note is not the same as a cash advanced note, it is an extension of the sale transaction for the payment of equity based on an agreed sale price.

Check your laws, consult with an attorney, and make sure you have anyone you are running a check on consent to it in writing.

Paypal does this and hs caught flak, you can't terminate the account without consent and if you don't have sufficient funds, you can get overdrafts.

@White KandlezIf you have don't have ownership rights on the property, I am not sure if you can have the property listed on MLS through realtor for sale without the consent of the owner on records.

when i do the whole hog rehab I do it to make larger profit. usually i rather do rehabs that do not involved the local authorities, permits and consents. these take longer and cost more. 

Just draw up an agreement that the lease is terminated by mutual consent, that they are the only tenants living in it, that they are returning the property to you and giving up all claim to it, and that they have given you the keys and have received their security deposit back in full. 

They state that they can't do anything without the owners consent (which would be the bank, right)?

years, without the written consent of Landlord.Suggestions/ Comments welcome.

My leases always had a provision requiring my prior written consent of any guest that stayed longer than 7 days.I'm with Tevis - serve a cure or quit notice.
