Use all of the proceeds in the purchase or purchases ($500K)Most folks don't have cash resources to replace the loan so they take out a similar loan amount. 

They are extremely responsive, have a ton of resources, and documented/standardized processes for everything you can think of. 

I suspect Sacramento is not close to being out of Bay Area people with 20% down moving to the area and looking to optimize by buying a multi (guess how I'd know...). 

I've explored short term rental options in the palm springs area but not sure that I would want this to be my first experience in the real estate business although I do have good resources where I can hit the ground running (or so I believe).

Obviously a very rural location is not optimal.

@Mason Haley as far as finding an owner's primary address for direct mail, PropStream is probably your best resource.

The service also includes a simulation tool to backtest and optimize each portfolio.

You'll be able to have access to the MLS, a very resourceful tool in running comps against a subject property.

If there are any resources I need to go through please guide me.

Any and all experience, stories, resources help!
