Hi Kyle. First, it sounds like you can't afford a property manager. You need to handle this on your own. Also, of course you have to disclose to them you are the owner. They will figure it out soon enough and feel you are dishonest if you didn't tell them up front. I would strongly advise always having an honest relationship.
Now, on your current home, add in maybe $200/month--for maintenance--making your payment $2700.
Next, think about if you were to sell the current house and rent something you could afford, what would your pricepoint be (i.e. what would you be able to afford), and what would that look like--an apartment, a 2/1 house, etc.? Can you afford maybe $1000? Can you find something comparable right now on Zillow in your neighborhood for that pricepoint? Let's use $1000 as your target personal payment.
If you can make that $1000 payment--the hypothetical rent payment--towards your current home, you need to rent the current place for a minimum of $1700. Try listing it at $1700 and be sure to list it as an apartment/duplex etc so people are prepared for the duplex situation. When they come to view it and see how big it is and the yard, they will be pleasantly surprised and more likely to jump, especially at that pricepoint.
