Banks will not like double escrow, but if you will hire a real estate agent in that area then you can do it.

Look at this blog it will help you to learn more about your situation.
I've got most of my answers there as well.

Good Luck.

I don't care who tells you how to do the double escrows but solid companies and agents will not encourage you to do that. It is a very high responsibility situation that could cause some licensees to lose their license.
I work with a lot of investors and cash buyers and i have to tell you there is nothing more rewarding than a smooth transaction and happy buyer. Email me and I will tell you how I and my team handle hundreds of investors with happy purchase. Banks are not willing to do it but hard lenders might.

Many title companies won't allow double closings. This is due to the increase in scams and ethical issues.

I have some cash investors who are looking to purchase(cash buyers) 3 bed 2 bath in vegas in the 5-10 pieces at once. Let me know if you could help here.

Banks and title companies are not allowing these types of transaction to my knowledge.
