What if 40% of the remaining 60% Loan To Value (ratio) is not paid, or the borrower wants to take only 60% of the loan?
This is the meat of your potato question. The rephrasing of the question to a lending/real estate executive such as myself, I'd ask, what's the scenario? "I would say you're looking for an Owner Occupied, Super Jumbo Loan with 20% Down or $360K down on the purchase price, $1.8 mil purchase price, Loan Amount is ~$1.45 mil. Fico is strong (assumption). If this is your scenario, please see image. Yellow is important, more debt increases your backend-DTI which is not good for the deal. As long as it's less than 35%, you're okay.  Can someone do this loan, the short answer is yes. It's smart that you want to keep more cash on hand. Which is understandable, if the price of the property declines, you've lost your shirt and your down payment, then it will take close to 10 years to recover your down. Consider that you are buying at a peak in real estate prices. Prices can't go up more than they are now. Consider that properties peaked in 2006, cooled in 2007, and crashed in 2008. Properties declined for more than 25-45% in 2008; regardless of your reasons of not wanting to come to the full 40% down, it's a bit smarter to hold on to cash for other investments purposes. Just incase a recession does hit.  In the end, if you do the deal-You'll pay more in points, a higher rate compared to the 40% down scenario, the origination fee would increase slightly but you'll keep your money on hand to invest elsewhere, perhaps some units that can help with the cashflow of your home. I've highlighted in yellow what the most important factors that will be affected on a lower down payment. If your debt is low or zero, and income is as high as the scenario, with a fico score of at least 680, you can do the deal all day long. These deals are not uncommon in today's market. Rate will vary. Don't pay attention to the rate, the rate will fluctuate based on many variables, but it's a high figure to give you an idea on total cost and monthly payment for qualification purposes, also to look at the DTI requirement for cash/debt.
