Paying off properties vs buying more

[Jason Schmidt]

What is your goal, and why? Apparently where I am at, property appreciates very slowly. My thinking is buy one at a time until they are 100% mine, then go to the next one, as opposed to buying 10 now and having to take on all of them at once, and worrying about multiple vacancies. At a cashflow of $800 a month on a 100k house, it would take 4 properties that are not paid off with a cashflow of 200 a month to be the same. Am I missing something?
