Not sure what to do

I am in the process of putting my house on the market (Scotland) after having tenants in it for the past year. However, it is in a rural area and could take ages to sell. I have no mortgage on it but really need to take some of the equity out of it as I am now retired on a low income. If it doesn't sell would I be able to remortgage in some way, to allow me to take some of the equity, and rent it out again? Thanks for any advice.
