Get investors to pay $4mln, loans for $6mln. Cash flow is $600k/year from avg of $1000/mo. 2. Slowly invest in the property, refurbish units by maybe adding in-unit laundry for example. Keep property well maintained. 3. After some time (3 years?), get property re-assessed and now its worth $15mln. Refinance the property to $15mln, pay off $4mln to investors, take $1mln from loan for renovation recovery/profit, tax free, pay off previous loan. The eye opening part for me was that the goal is to not build and sit on the equity like a residential house but use the equity and increased property value to refinance and the extra money from the loan becomes essentially tax free profit. …
