key largo options

I have a newly constructed residence in central Florida. it is fully paid for. I have had it listed for sale and have had a number of prospective buyers look at it. I am approaching a milestone of the end of Year. I need to make a decision of whether to keep advertising it for sale or to hire a rental property management company to find a renter for it. I would like to have someone create an economic model for my condition that would show me the effects of renting it year after year so that the tax value of depreciating the property is clearly understood in relationship to my taxes.
