I think many of us have been in your position (money, space....mostly lack thereof LOL). The other thing for you to be aware of is tooling. The lathe purchase is one chunk, but your intended work will dictate some other necessary hardware. These purchases can be spread out over time but still add up. And to a certain degree, this can be lathe specific. Spend some 'catalog time' spot checking how much chucks cost (3-jaw, 4-jaw, collet) & vs. maybe comes packaged with the lathe. They can be anywhere from a couple hundred bucks to much more. The lathe you are looking at may be a screw on spindle or specific back plate adapter. Nothing wrong with that, but you may or may not be able to utilize that stuff if you upgrade one day.
Next is toolpost & cutting tools. Again, nothing wrong with old school lantern or tool blocks, but some old school HSS shanks are actually hard to get and/or more money (like the lathe in your picture). You will be grinding bits (need a grinder) & just bit more fiddly to set up. The reality is there is SO much Asian insert tooling out there now at very reasonable prices, its actually more cost effective IMO. Again, do some internet research to see what guys are running on a specific machine of interest. The tailpost comes into play with whatever MT taper & therefore arbor/chuck size, but not a biggy.
If medium/small/lightweight lathe is just what you have to do, then so be it. back in the 60's & 70's when Myfords were all the rage in England & maybe similar sized Emco's in Germanic countries, hobbyists made incredible works of art because they were resourceful & found a way. The problem is, that era is gone. Even the guys that own the machines have given up on parts because donor machines are clapped out & replacement parts are unobtanium to expensive. The 'new norm' is Asian machines. Unfortunately the quality varies so you have to evaluate carefully. Look carefully into threading & speed changing capability. This is #1 & #2 source of buyers regret, but it all depends on what kind of work. If you haven't visited Stefans YouTube channel already do so. he has done some upgrades over the years but has also done some nice work in stock mode on a lathe this size.

I would also venture an opinion that milling attachments (on lathes) are do-able but are a PITA, moreso on small lathes. You are better off getting a tabletop mini mill. (I know, more money). If you're patient, used deals come along. Someone has likely bought the exact same package you are considering but when the dust settles, probably selling for 60 cents on the dollar if it hasn't been abused. The more that comes packaged, the less you have to spend. Also be aware of 'apartment machining'. A buddy of mine experienced some (essentially eviction) issues with the vibration transmitting through the floors & lights dimming on start & background humming noise etc.
Hope this helps
