It's impossible to make any sort of accurate predictions, you really have to just experiment.
However, it is extremely unlikely you'll cause TVI to your own or your neighbors' sets if everyone is on cable or satellite. The majority of TVI problems occur when people are trying to use "off the air" broadcast signals, and if your apartment complex uses a community antenna system with distribution amplifiers, and people are connected to that, TVI is always a strong likelihood. Those systems usually stink when it comes to RF immunity. Commercial cable systems, on the other hand, are usually excellent.
Other problems that are likely: Setting off smoke detectors, and getting into neighbors' telephone lines which can interfere with not only their telephones but also computer modems, FAX machines and anything else they happen to have connected.
The best way to avoid all these things is to get your antenna(s) up, outside, and away from the building if at all possible. Two ways I accomplished that when operating from a condominium (similar to an apartment, except I happened to own the unit) in the past:
1. Installing a wire multiband inverted vee in a tree at the edge of the condominium common property, and feeding it using a nearly invisible run of black colored coaxial cable that ran behind shrubbery a long way and eventually entered my unit via the garage (under the door). In this case, I had cable loss and risked having the cable cut or damaged (although it never was), but the antenna was more than 100 feet from my unit, or where anyone lived, so RFI/TVI problems were zero, even when I ran 1500W PEP output power on the HF bands.
2. Installing a coaxial cable run through a rain downspout all the way from the roof of the condo (over 40' high) down to the ground, and then into my unit via a dryer vent; then, clandestinely installing ham antennas on the roof, accessed via a fire escape. This was tricky, since I was trying not to be caught in the process, but it all worked out perfectly and got my antennas about 45' above ground and installed in such a way that they were impossible to see from anywhere, unless you happened to be flying over in an airplane. Also, in this way, my antennas were at least 30-40 feet from any neighbors' living quarters, which again, goes a long way in reducing RFI/TVI.
