A 3br/3ba luxury apartment near a major university.Rent was $2950/mo and it made me $1600/profit per month.With two units and within 2 years, I was making $4k/mo in profit from 2 airbnb’s I didn’t own and I only started with $10k.I replicated this process until I brought on a business partner and hired a full time operations manager and we scaled to a 17 property portfolio between rental arbitrage units, management deals and properties we bought.I did this strategy in my early 30’s and I’m 33 yrs old now.
