Axel, congrats on the new acquisition and continuing to crush it when many are saying "there are no deals to be found in this hot market!"
About a year ago I built a small multi-family building and the sweat equity I put in as the GC ended up covering my 20% equity (and then some) the lender required for the final loan. I walked away from the closing with 8 brand new units that cash flow well while not having a dime of our capital left in the building. It was at that point a light bulb went off and I learned the concept of "free" that you mentioned. This pushed me to do a cash out/refi on several of our small multi-family properties to provide the capital needed to grow our portfolio instead of the money just sitting idle. I wished I had truly understood the velocity of money years ago when I first started my investing journey.
Axel you are spot on in that investors need to get creative in structuring their deals/financing in order to scale and create momentum. Amazing post that all real estate investors should imprint in their mind!
