@Andres Vanegas this prevents you from ever having to spend any of your money. Instead of exchanging 100k worth of currency for 100k worth of real estate, you just get the real estate. It's a massive net gain. Also cryptocurrency is arguably innately more valuable and (in most cases) deflationary so it will increase in value over time and is itself an interest bearing asset. If you use Alchemix to take the over-collateralized loan then the math looks like this...
200k locked + 100k loan. Exchange 100k loan for 100k house. 200k collateral pays for itself and the house now earns rental income. After 1-3 years your 200k collateral comes back to you. So 200k + home. Of course you could be even fancier about it and do something like this...
Find a home that is amenable to BRRRR. Put 100k into the BRRRR deal, the refi step now yields back 100k. Pay off the loan immediately if you so choose and now you end up after 6-12 months with...
200k + an income yielding house and you haven't lost a single penny of spending power.
You can get fancier still and funnel the refi earnings back into another DeFi product that will have its own massive return (the options are overwhelming). To give one example you could take the refi earnings and put it into the Alchemix vault in order to further accelerate the loan pay down (which is currently at something like 30% boosted APY). So your loan goes from repaying itself in roughly 1.5 years down to let's say 8 months. So in this scenario you walk away with 200k + 100k + the house. Again, having spent zero of your dollars. So assuming you have the patience to wait 1-3 years then you keep your 200k, you make 100k, and you get the house.
