I am far from an expert in this area, but since I recently purchased a new home and I am still trying to sell my old home I might be able to add something. The best advice is probably to spend as little as you can on your landscape. Spending $200 to spruce up your yard might be worthwhile, but $1,000+ is a waste. Somebody will purchase your home because of its location, the number of bedrooms, the layout, the number of baths, the neighborhood, and similar features. They will not purchase your home for the landscape. So why spend any money on your landscape? The reason is that potential buyers want the impression that they are purchasing a house that has been loved and maintained. If they notice a dozen problems before they even get to the front door, then they will look for other problems. Another reason is the real estate buzz word "curb appeal". The front of your house will be the fist thing shoppers see when they drive by or search on the Internet. Looking at the pictures, I agree that you should make some improvements to your landscape (provided that the inside of the house is in good shape). I would likely not remove anything that was not dead or in real bad shape. Prune back the overgrown shrubs, get some grass in there, get rid of the weeds, spread some mulch and straighten up. Removing the lower limbs from the spruce would open up the front of your house. You are not going to be able to create a dream landscape on a tight budget in just a few weeks, so do not try. - Brent

Landscaping is about how a house fits into a setting. In this picture nothing at all can be told about the setting. You need a picture that is square on from the street. Pan the camera from left to right capturing the scene in slightly overlapping shots ... all from the same, central point of view. Post the individual pictures that make up the scene, not a computer generated panorama.

Some very drought tolerant plants I’m familiar with here might do well there, caryopteris, Gaura, baby’s breath and gaillardia. Oh and I just thought of statice, ratibida, salvia, Oenothera and penstemon too, I’m sure you must have some local natives too.

Would move the agave beneath the window to the right side of the window, hopefully maintaining some sense of symmetry. Then center whatever decorative feature you add in front of the window. Consider an inexpensive basic DIY bench the same width as the window -- one ttat could be used for sitting or could be used for setting potted plants atop it. https://www.google.com/search?q=basic+DIY+porch+bench&tbm=isch&ved=2ahUKEwj2gu7O2aDpAhUDM1MKHQa1DbQQ2-cCegQIABAA&oq=basic+DIY+porch+bench&gs_lcp=CgNpbWcQDDoECAAQQzoCCAA6BggAEAcQHjoICAAQBxAFEB46CAgAEAgQBxAeULm5AliT3AJguuoCaABwAHgAgAFjiAHcBpIBAjEwmAEAoAEBqgELZ3dzLXdpei1pbWc&sclient=img&ei=tnGzXvbPEIPmzAKG6ragCw&bih=648&biw=1358&client=firefox-b-1-d With the same wood as your bench, you could create an arbor over your window at fascia h eight and you could attach a few hanging baskets to it that could help shade your window, along with any plants you set atop the bench. Or you create a bench or swing within an arbor. For your yard, consider a plain concrete bird bath that could be seen from your bench or from within the house via the window. They can be painted. https://www.google.com/search?q=plain+concrete+bird+bath&client=firefox-b-1-d&source=lnms&tbm=isch&sa=X&ved=2ahUKEwjI_uy92KDpAhUmnOAKHfxHAcwQ_AUoAnoECA4QBA&biw=1358&bih=648#imgrc=dsz70E8M3SUeNM&imgdii=iZqdglX3zjCO3M
