Also, you can't legally sign a new lease agreement without the Tenant's consent.

The Ohio Division of Real Estate recently published some yearly reports that detailed all of the fines, punishments, license suspensions and license revocations they've issued to people for illegal activity.Below you'll see wholesalers who were fined for illegally brokering real estate as well as an Agent who was fined and had his license suspended for working with wholesalers. 

The seller can place the property into an inter vivos revocable trust, and then at closing change the beneficial interest of the trust. 

As for your situation, just go for the non revocable trust.

I agree they should not have touched the plumbing without written consent from you.

A judicial foreclosure in those Canadian provinces which use it, the lender must file a Statement of Claim before the Court of Queen's Bench to obtain consent to proceed with the foreclosure.

or should I also have an affidavit signed and notarized stating he or she can not sell to anyone else without my consent?

I was never informed of this until recently and I don't know how he could have sold my property without my consent but it may have been another scam he could have planned on the potential buyer.Ironically, I got the news of McNutt's arrest from another management company I hired after McNutt and terminated also within a short period of time because they were going out of business without telling me ahead of time.  

@Trent Egenlauf The first thing you will want to do to run background checks on potential renters, have them fill out and sign a rental application giving you consent as well as their personal information to run the check on them.
