For example, if you have $200k saved up, then if I could get into 10 - 100k properties (20% down on 100k is 20k x 10 = 200k). 

I am a relatively new investor that has gotten my feet wet by using my own savings to buy my first deal. 

We're in the saving phase and we're about 1/2 way to having a nest egg of 6 months of expenses.

I have been doing a very slow crawl (while I clean up past financial mistakes & save cash for future successes) to get into the investment side, but have been working to gather some priceless experience along the way.We purchased our first home in 2005 and that became our very first rental in 2009!

I can pay for the downpayment via my savings, but the property appears to need a full rehab for both units. 

I could just put it all on a credit card and try to pay it off over the next few months with my personal savings, but I could also try to either borrow or add it on to the purchase price.

Its not highly likely and will set me back 3 years worth of savings.

I then save or scan everything to an encrypted drive and shred any paper. 

I’d say sell that property before something goes wrong then go back to square one, save up for a down payment and ample cash reserves for when something inevitably goes wrong, establish 2 years solid and consistent income, build credit, find a bank to work with and start over again in a better asset class.

In my area of the country, if you can give more value for money than an absentee landlord mailing it in or a faceless management company rapaciously intent on maximizing their profit per unit, you're never going to go broke with rentals in the $700-$1100 range, good economy, bad economy, whatever.
