How do you get multiple properties rehabbed in a single year?

[Mike Brown]

Say you have enough money to buy 4 rental properties to BRRR in a single year. How do you get them all rehabbed in that single year? Do you hire a single contractor who works on all of them at the same time, or do you have to hire multiple different contractors to work on each property?

Also, how long do rehabs normally take?
