I am glad that among all the options you picked the most innovative one 😂.
Let's think of all the ways you can lure them to your apartment in the first place.
Jokes aside, definitely do not want to hold them against their will or they may teach you something wrong but maybe you can bribe them. Though I have to say even with the tutors, you end up spending most of the time studying on your own because they don't need to reach chapters to you or watch you do homework. All you need to do is cover some material, do some practice, and then they do correction, so the face to face time is perhaps 1-2 hrs per week and you can honestly probably gain it on GMAT Club just posting to see if you are on track.
P.S.
(moving this as a separate topic for a few others to perhaps benefit from this innovative approach)
