Selling to tenants: commission ethics?

[Jack T.]

I have a rental property that is professionally managed that I was thinking of trying to sell to the current tenants. I have no relationship with them but thought I would contact them and see if they would be interested in acquiring the property. I bought the property only two years ago, but my realtor steered me badly on the expected property tax ($4,500 on a property for which I paid $162,000), making this a poor cashflow property. However, the property his now worth about $220,000, (but no correlating market rent increase) so I thought maybe an easy way out would be to offer it to the current tenants, possibly offering seller financing. Would I be unethically bypassing my realtor or property managers (also a realtor)?
