I vote Coyote. Based on your location. Coyotes do quite well in suburbs where small mamals are plentiful. They are pretty elusive unless they have babies nearby. You shouldnt really see them during the day. If you lived further south, I would have said red wolf. They are similar in size to coyote, with a snout that looks very close to what your photo has. We are lucky enough to have some here nearby (National Forest just a few miles down the road), and they are on the way to recovery. Of course we also get bear and deer. If you have bird feeders near that brush, you are likely to see more wildlife like Mr Coyote - easy pickins. The birds eat and spill seed, small mamals come to eat the seed, and house cat comes to eat small mamals. Mr Coyote is doing what comes natural. If he gets close enough to get photos - I personally would relocate the feeders (if you have them)further out and or avoid throwing food for the birds. Enjoy him from a distance but don't encourage him.

The wood looks pretty rough. If it is just in need of a good cleaning/restaining/sealing...I would do that. Otherwise, wait and see what you decide after you have lived with it for a bit.

I need a lot more info a to scale plan of the space and is the sun room staying ?IMO it is poorly constructed and not what you want. It seems to be part of the living space so I am a bit confused Post the plan of the whole area this townhouse sits on showing where the actual townhouse sits and how the sun room relates to that . All meaurements clearly marked and show where the neighbor is that you mention. Can this "room" be removed there are always rules in townhouse properties so check those out .The fence I see seems to be in an odd place so is the area in fron of theat fence useable property or is the end of your patio the end of the property I really need a plan

Have you considered paying to have a landscape design done? If you're comfortable paying to have the landscaping work done professionally, it might be worth the investment to have a plan put together. Potentially you could have them design phases if the complete design is too expensive for your inital budget. (A friend of mine did that: paid for a professional design with multiple phases to be completed over several years.) If it were my space, I'd want a nice big patio section with some kind of sun cover if possible. Love the pergolas with sliding shades that Oly posted. I really want one myself. Think about how you'd use a patio space (dining, lounging, cooking, etc). I would want some area for my dog to run around and catch a ball and a space for her to go to the bathroom. I think grass or groundcover are nice, but decomposed granite or bark would work too. I find rocks bigger than pebbles can get to sharp for her to run around on, so I wouldn't use that in any areas you want the dogs running around. I would also consider adding layers of trees and shrubs to bring life to the yard. They can be low maintenance and add a lot of beauty. If you can pick native species, that should help them thrive. I do think tiered landscapes can be very attractive, but I would want something with stairs to access higher levels. If you can afford it, rock retaining walls can look really nice but probably cost a lot.
