Barring market specific factors, I am very confident in the MF market. 

I'm an investor from Portland OR, doing mainly fix and flips and the occasional lease option over there.

There are a lot of factors to consider.

I've had a few discussions about the best way to create a plan in order to "snow ball" your way to owning many REI properties (buy and hold for rent).After Googling around and even reading blogs on this site, I've thought about doing something like the following:Buy my first rental property (SFH) with cash (around $60-70k) where I'd expect about $500 cashflow per monthCurrently I have about $105-110k available (after taking out an emergency fund)Then shortly after, buy my second rental property (SFH) but take out a mortgage and put down around 25% on a $60-70k houseThe cash flow on this property specifically would likely break even (at or near 0) but this would be on a 15 year mortgage and I can use some (or most) of the cash flow from the first to help pay down that mortgage faster, along with my corporate job monthly savings tooI feel I could pay it off anywhere from 5 - 10 years depending on the exact strategy If/When I get the 2nd one, then shortly after that, try and get a 3rd SFH rental property and continue this snow ball effect to build up by rental portfolioObviously this is easier said than done, along with risks and I honestly do not have any real experience with rental properties as this is my first time diving into this type of investing.My main questions would be -- Has anyone done a similar strategy to help build their portfolio quicker?

I will try to be brief with the many confusing details and factors that are making a decision difficult for us.The house is a SFH near Seattle.

Mainly a realtor who is familiar with investment properties is preferred. 

I pay attention to many factors of other apartments in coming to an understanding of what rent for my place in my target area should be.

I am trying to get a business line of credit using my EIN mainly to establish business credit..

Hypothetically speakings, lets say I have a bedroom on the main level that I wanted to rent, but my neighbors dogs eliminated that option, so I put the bed in the basement?

So be sure to factor that in.- Tom
