Generally when sellers say "cash" it really means they do not want to deal with contingencies,  short closing period and/or do not want to deal with needed repairs. 

@Sarah Hadassah Negrón so you get a money judgment.Now you have to turn that into a garnishment action with the courts.To do that, you typcially need to have the tenant personally served - which means finding them or hiring a skip-tracer to do so.Then, what are you going to garnish?

What do you do?  

Because if you do, they are one of the few states that will require you to pay their tax after you’ve left the state.

Happy to connect and knowledge share if you are interested.Detroit is a great "fix & flip" market if you are on the "right" street and don't "over do" the flip.

Do that for six months while you save more before making a decision on what to do, especially on doing it out-of-state.

I'm currently under contract for a piece of land with an off-grid cabin - doing as a land loan.

For these reasons i am confident you do not need an account per unit as having that requirement would be crazy complicated (the opposite if kiss).in addition, how will anyone know that you are not following the law?  

Thank you Jay 👋 Do you invest in real estate as well as act as an agent?

But do you due diligence, protect yourself and be prepared in case it happens.
