I just purchased my first duplex, and am following the advice of @John Casmon in renovating one of the units, moving in, then finishing it off before I put it back on the market at significantly higher rents in the next 6 months. 

If you are going to live in the property, I would just suggest that you follow the terms of your leases exactly and rather than tell tenants you are the owner, just introduce yourself as the property manager.   

From my understanding, the various phases of a wholesale deal include the following: A call is received from home owner as a result of marketing efforts Provide a range that we (wholesaler) would be willing to offerReview property and required renovations to determine selling price to market to buyers listGet contract signed by home ownerRecord contract with countyMarket property to established buyer listOnce buyer is interested complete the assignment contactReceive deposit from buyer and put in escrow with title companySet closing date with title company for double close Did I miss anything related to the process?

I'll spend some time following these leads.

From my experience, the tenants have follow the rules set forth by the housing department and the if they have complaints filed against them they can lose their voucher. 

I would send this letter this week.Let a week pass and then follow up with a call and offer a "pre-inspection" of the unit to see if they have any questions and to determine the condition of the unit for renovation work.

They can follow up with the CRA to get a copy of their report.You're in a tough spot in that you may offend the current renter but it's your job to get the best tenant(s) in your rental.

Following the topic.

I'd evaluate their management style and way they operate the park (i.e. collecting rent, following the rules and regulations, notices being sent out regularly, etc.).
