Confirmation of financing sub-100K properties

[Kevin Tran]

I've read Brandon's book on land lording and now reading The Book on Rental Property Investing. In chapter 3 he gives four sample plan on buying property. Plan 1 talks about buying a $100,000 4-plex at 80% and financing that amount. How realistic is it to find and finance a 4-plex with those terms? I'm a Realtor and receive emails for non-MLS property sales but they are always for cash or hard money. The plan falls apart if one has to buy properties with all cash. You all are the pros so I'm hoping to get confirmation that while the example dealt with ideal situation and round numbers, if the scenario is more than a far-fetched fair tale. Thanks in advance.
