I looked through some paper work and saw that the first real estate loan they received was for about 105k.

Essentially, the bank will give you a mortgage for $80,000 on the property you paid $50,000 for. 

These are essentially business credit cards.

I don't know about a general percentage but we had a loan through family and essentially paid cash for our house.

Get your paperwork in order and get Supra access ASAP. 

So how do I start the paperwork process with an attorney ( who I must pay) without charging any processing fees?

It is essential to be able to communicate very clearly and receive very itemized estimates for any work contracted out!

My trip is essentially a vacation, but other than enjoying the unique touristy things each city has to offer, I really want to use the bulk of my time to explore markets and dip my toe in the water of investing, exploring different neighborhoods, looking at properties, talking to agents, investors, and whomever else can provide valuable insight on what I'd be venturing into when I'm eventually ready to buy.My intention with this post isn't really to turn this into a sort of journal with periodic updates, but mostly I was hoping that this post, and perhaps others in the future, could help me connect with some of you more experienced folks out there who may be willing to lend a helpful hand in anything at all real estate related. 

My knee-jerk answer is to tell you to sell, especially considering you will be essentially making nothing (and actually losing money when you factor in vacancy, maintenance, etc), but you should really talk with some other Washington investors:@Steve Vaughan is a good place to start. 

His team can offer services at $500/mo to manage bookkeeping for essentially 4 businesses.
