Let's assume that the Seller provides bank statements that shows the tenant is paying rent every month,  the Seller is not willing to provide the property vacant, and my goal is to buy and hold. 

Goal was to make them pay for the most expensive ones, to break him as fast as possible. 

You should discuss your goals with a professional well versed in SDIRAs.

What is your goal with this property..House hack, flip, buy and hold ????

In our current situation we are saving 4-6k a month and look to boost that to 5-7k a month in order to acquire more properties.The end goal is to be able to live off the passive income in 8 years.

Some days I feel like all the maintenance calls checks going out each month just isn't worth it, but most days I want to head towards my goal of $10,000 cash flow a month. 

You're both very young and your lives, goals, and personalities can change on a dime.

It depends on your goals @David Vargas.

You need to look at your goals and what you're willing to do to get there.

My short term goals to get started would be to get into the wholesaling side of real estate and earn capital to eventually invest in purchasing properties on my own for renting and also fixing/flipping.
