So, if Grand-L is a bit excessive for a second property, then it's B2601 or LX (if older, then used to be called Bxx50, but basically the same machine). Stay away from the B3350 if you're in the old "large frame B" - the emissions controls on them were problematic. They're mostly sorted now, but no reason to buy a problem if you're buying now.
So, that gives you:
- B2601
- LX2610, LX2620, or one of the more powerful LX machines if you want that HP to blow snow
- B2650 (the older version of the LX2610)
All are available with SSQA, and if a used one doesn't have SSQA you can add the adapter.
Between those, I own a B2601 and it's a good machine. The LX2610/B2650 have the same HP in a larger chassis. You haven't described anything that needs a larger chassis. I did this table years ago on the relative capacities of the machines, from memory the LX will do about 15% more on most metrics.
A table I had made for BX and B01 when I was looking. I've seen a few questions on differences, so thought I'd post the full table including the B50 series (and now L2501 as well), because lots of people ask about the differences. Really no question or point in the post beyond contributing...

In choosing, I'd say:
1. What's available used near you. A good machine at a good price in either size is more important than which size you buy
2. Do you want a cab. That really means B2650 or LX26x0
3. The LX2620 had some hydraulic changes that made it quieter to run. People who don't like HST whine are quite excited by that, and apparently with a cab the whine is amplified. Maybe worth going new to get that.
4. Do you want the slightly bigger machine - if a B2601 will feel too small, then obviously you need to go B2650/LX2610
5. I think the B2650/LX2610 had a digital dash that some people don't like. If that's important to you, then B2601
Hard to go wrong here, these are solid machines that will do what you want. Perhaps the decider would be finding one with a snowblower already on it? I can't recall if they both take the same snowblower, and I seem to recall the quick connect is a pricy piece of kit.
