There are so many benefits to house hacking, one of which being that it is a great intro to real estate investing that will help prepare you for other types of investing.

But I do need to be prepared with interviewing backup cleaners if things don't work out.

When doing a cash flow analysis for a multi-family, what does a free cash multiplier entail?

Forced PCS’s 2x and now preparing for separation like you.  

I have recently thought about doing this myself for a few reasons, but I can say that 2 years ago, while the general RE market was so hot that flipping was a cash machine, it just wasn't a time in my journey that I would have been prepared to take it on.Other than that, just keep doing what you have had them start.

What are some other ways I can prepare myself?

Yes to both...best to be at or above competition in terms of finishes or sell to someone that will properly prepare the house. 

I have bought many pre foreclosures, I focus on underwriting and preparation.

Either way you will be treated with respect...prepare a list of questions to ask when they call,and ask for an appointment.

I only use leases prepared by my attorneys in the 2 states we have rentals...the attorneys will be defending them in an eviction, and you want to make sure the terms are legal and up to date.
