Hi Susan
According to your profile you have over four years experience as host so I am sure will be quite familiar with managing your listing so I will focus on demand and pricing.
What market research did you do around supply and demand before starting up your STR business with two listings, to understand what the STR market is like and whether it was likely to be profitable for you. @Susan3725
As you know many areas are suffering from over saturated markets coupled with falling demand due to the recession.
How many days do you estimate you will be booked per year ? at what day rate.
If you plug your likely income figures into a profit and loss account with your one off and ongoing costs you can see how profitable you are likely to be and therefore whether it is worth doing STR.
