@Dan Robinson 1031 exchange is only available for properties it is your intent to hold for productive use in business trade or for investment.  

I am looking to get into to wholesale/assignment deals, house flipping, and would like to move into holding properties for cash flow. 

Do you want to buy and hold, flip, etc?  

Unfortunately, he's not in a situation to hold that mortgage and he won't be able to pay rent either, unless if your plan is to have negative cash flow.

I'm interested in SFR, Multifamily rehab and buy and hold.

I am eager and willing to  learn as much as I can about real estate especially buy and hold and multi-family unit investing.

If you invest and hold out of state, you need feet on the ground to manage.

Check out Hold by Gary Keller as well.

So, in my market it generally makes more sense to leave it a SFR, unless you are going to totally blow it out to a huge multi-family, max out the square footage on the lot, and hold a long time.

Strategy is buy and hold value add
