I agree with John and Bob. In retirement you want a consistent dependable income stream and security with regard to your housing. If you can take that 50K per year and start investing it in real estate backed income producing assets (rentals and notes) for an 8-12% yield, you can begin setting up and growing that income stream. That stream can then be used in the short term to pay down your mortgage more rapidly and/or buy more income producing assets. Given the rates on your loans, I would favor continued building of your passive income stream.
Your area, like mine, is not the right place to invest for income. As Bob points out, the Midwest has the opposite side of that coin, i.e., not much value appreciation but you can buy properties which will cash flow very well as rentals. Buying as turn key is a good option, but you need do some research to find the better turn-key operators. Buying rentals has a distinct advantage over notes for money which you have outside of retirement accounts. Rental property depreciation and operating expenses will generally shelter most of the income you receive from taxes. For money you have in your retirement accounts, I would recommend moving that to a self directed IRA and using it to buy real estate notes or make hard-money loans to local rehabbers. The local REIA is a great place to meet good rehabbers who need these loans.
