@Donald Coleman I chose to go the online course route, but I'm an introverted self-starter, Type A, online-learning-lover and wanted to get my license faster than a traditional in-person course would allow.

From our traditional bank 1st mortgage holder we can get an option of a HELOC with a 1-year fixed rate advance with a rate of 3.235% fixed for 1-year and then a fixed rate of 5.5%.  

If you rent out one unit for $2,000 (the high side of Abel's range) that means you're out of pocket $3,000 every month, and on top of that you don't have any money for a surprise large capex item.

I tried, before the crash, to take 80% equity out to buy another unit but had zero luck at securing traditional funding through a bank.

From everything I've read in books, It talks about itemizing exactly what brand/color/etc. you want of everything.

Any traditional lender is going to require that you have capital of your own.

I'm a big proponent of very specialized 1st position Heloc that has the staying power more similar to that of a traditional mortgage.

An IRA can only be funded in one of the following methods:Regular ContributionIndividuals who have eligible compensation (generally earned income) and meet certain other requirements can make regular contributions to Traditional and Roth IRAs. 

@Joe AbughazalehI understand that the interest will be higher then traditional type of lending.

With 2 additional partners, it would need to be spelled out in the beginning as to how the breakout on sale would be and who would cover what when additional items are needed.For me, I wouldn't go after it.
