PP have pretty much covered everything...
But I will say the overall impression is of an unloved and uncared for house. If you as the owner don't care about it, why should a prospective buyer?
And as for ripping out the lawn - is the EA who recommended that the same one that did the terrible photos? Because they clearly don't have a clue about presenting and marketing a property. S/he is an idiot.
This is supposedly a family home (4 bedrooms) - the outside space is important. And it has been ruined, and leaves a huge and expensive job for the new owners to do before they can set foot in their back garden.
And honestly if your DH has been making all the renovation decisions then he's an idiot too. For ripping up the lawn, for leaving clutter in the house (a stack of pictures in one bedroom, clutter in the - horrendous- kitchen), for not weeding the drive and back garden, for accepting the awful photos - it just goes on and on.
Sorry OP but you really need to start again with this one...
