Accumulating Rental Properties

[Andrew Merritt]

I'm working on finding a rental property as my first deal.  For right now, I'm focusing on pretty much turn-key properties.  If I stick with this and spend all of my money allocated for real estate on this first property, how would I go about getting my next property (and more after that)?  If I was to get a loan for 80-90% of the equity in the house, I'd quickly reach the point of diminishing returns and I might have a 'seasoning period' to take into account as well.  It seems like this isn't the best way to build a portfolio.  Or it would just take forever to save up enough to buy the next house each time (depending on my savings rate, of course).  

I have no experience w/ renovations, but I feel like BRRRR is the only way to build a portfolio in a reasonable amount of time.
