@Shiloh Lundahl I'm new to this. But I'd assume this may be a bit short sighed in 3 areas.
1. Appreciation over time. Equity in properties you own will give you more money to invest in more properties.
2. Appreciation of Rent. That same appreciation will also allow you to refinance the rental, dramatically lowering the mortgage while rents are also appreciating. Brandon and David constantly mention the acceleration that starts to happen 10-15 years down the road and that real estate is actually a slow play. My rent in 2014 was 1150. It's now over 2000 to rent that same apartment.
3. Robert Kiyosaki's strategy to winning Monopoly; "Buy four houses, and sell them for a hotel." Sitting on small margin rental properties is probably not a common strategy experienced investors continue with. I'm not sure how many of the podcasts you keep up with at this point, but I've heard them ringing home the strategy of doubling your doors and how doable it is. So instead of counting by 1s to get to 50, you start exponentially expanding. 20-30 small family homes does sound like an intense goal. One 50 door apartment sounds much more attainable.
Don't let the doubt creep in!!! It will only close your mind to the opportunities in front of you. Believe in your vision and abilities to attain it with absolute confidence and let your WHY drive you everyday with absolute perseverance; and you will see paths to victory all around you. It's strategy plus mindset! Good luck fellow investors!
