Pros:
The actual unit I lived in was nice. And the location was great. But I cannot under-emphasize that the cons substantially outweighed the pros.
Cons:
Highpoint Associates X/Mashcole Property Management/Keystone Property Management, whatever the landlords call themselves are absolute criminals. In the wintertime the heat would frequently go out in this building and it would often take as much as a week, sometimes more, to get it repaired. Communication to the landlords (who are based in California) about this, if it was addressed at all, was often met with disrespect and gave the impression that we were bothering them with trivial issues. The same was true of the hot water, which frequently went out and took at minimum several days, once as long as two weeks, to repair. The same was true of pest control - without going into detail, after numerous attempts to get the landlord to send an exterminator, and a landlord's broken promise to do so, eventually we gave up and stopped asking when the landlord stopped responding to our emails on the subject and just went AWOL for several weeks. After moving out of the building, chiefly due to our horrible experience with this landlord, the landlord did everything they could to avoid returning our security deposit, delaying for months and making arbitrary deductions when they did finally return the deposit, presumably on the too-often correct assumption that the tenants don't have the time or resources to take them to court (the same is true for all other issues with the building - I'm confident that this landlord believes that if they do nothing for long enough, tenants will simply stop asking them to fulfill their obligations in the lease and will try to find a way to handle it themselves).
The upshot: the landlord corporation (whatever they call themselves) does everything they can to exploit their tenants while simultaneously doing as little as possible to actually make the building livable, including in areas related to fundamental tenants' rights (e.g. heat and hot water).
This is not an extensive account of the cons of this building - an extensive account would take too long. Additionally, I'm omitting some significant problems that are specific to me because I'm worried about retaliation of some form or another. But I should mention two other things to be aware of, briefly stated: the elevator was frequently broken and often took a very long time to repair, and the buzzer didn't work for the entire time we lived there. The latter issue was repeatedly raised to the landlord and to my knowledge no effort was ever made to fix it.
Advice to owner:
Treat your tenants with respect. I understand that you have financial motivations to do what you do, and I'd imagine that your behavior is frequently profitable, but what you're doing is actually hurting real people and you should be deeply ashamed of yourselves.
