Some people dont even intend to get that many however if you are trying to maximize 10 from each partner/person then you'd try to qualify and hold title separate for your own 10 prperties (10 + 10 = 20 total properties).You can also look at credit aspects as well but typically lenders will use the lowest of the 2 middle scores (3 scores per person but will use the middle score).So the most important aspects are the income to qualify for the loans in the case of full documentation loans.
