Is multifamily deal closing time reducing?

[Parag Goswami]

Spoke to a few lenders and apartment investors, I learned the average time it took to close a deal 24 months ago was about 90 days and this reduced to about 60 days in the last 12 months. Some deals close in as low as 30 days today. 

What's causing this decline in closing times? Lower interest rate market or investors taking risks without doing full DD?
