I plan to pick up 4 more properties  in the near term to buy and hold and raise capital.

If you have any money left Fema will raise your flood rates higher because you are a landlord and not owner occupied.

Like @Jeff Graves said, Facebook ads would likely also do well, and that gives you a chance to inexpensively test your messaging & audiences.

Finding new tenants every year, dealing with room mate issues, damages, having to include all utilities and even TV and internet (many student landlords do this) all raise costs.

Will the time I put into the fix & flip projects be relevant experience to count towards the 4500 hours required to test for my PMP (assuming I'm not using a GC)?

On a scale of 1-10 for level of difficulty I give the test a 7.

Is there enough equity in the property in which you can sell a portion to a private money investor or an investor partner to raise the down payment? 

Again, no education or training involved with this process.There are no tests, no certifications, and nothing else to stop your average, uninformed, real estate agent from making offers on HUD properties.  

At least 40 raised their hands.  

Raising capital for EMD and GAP amount needed to close loan is what I need to know?
