Second-hire a reputable property management company that will protect you and your property.  

If you don't know the buyers personally (enough so you can call and ask questions) strongly consider taking another directionFriends don't let friends do bad deals, listen we all want warm fuzzes when working with people but the reality is, your running a business. protect your self at all time - its not personal its business. be objective (AND THIS IS HARD) but houses, don't have feelings, wholesale fee's don't have feelings, title company stamps and legal paperwork have no feelings, if your the feely type get a hobby or pour your emotions in another venue. real estate (demands) you to be at the wheel, and be ready to face the ugly truth."

The NEW lease-option design...As I understand it, one of the requirements of the new Consumer Finance Protection Bureau, birthed from the Dodd-Frank legislation, is that ANY lender in an installment sale has to verify that the borrower is capable of repaying the loan, just like a traditional mortgage lender must.

Laws, customs, standards of practice vary enough within our own country....going abroad with your money is just a large risk to take if you do not know what you are doing.

Exceptional customer service...

This will protect you if the sale falls through and added insurance the buyer is serious and able to close.  

And volume doesn't have to be multiple projects, it could just mean buying more of the products they sell.My personal suggestion is to find a really good sales rep who knows the difference between landing a sale and landing a customer.

I believe that forming an LLC protects your personal assets and credit rating.
