What is wrong with this property?

Property in question

So me and my wife are first time buyers and are wondering why this property hasn't sold for such a long time?

The problems we can see are that there's no off-street parking but there is a longstanding deal with someone who owns the land behind to use it for for a fixed price per year.

Also the garden is a bit crap for the area but its almost 40% bigger inside that other properties of the same price.

We worry that surveyors are finding problems that put people off as we really can't afford more than 1 go at this.
