Ask for the duplex to be delivered with an empty unit and maybe the seller will oblige.

The one I’m trying to buy never hit the market as my agent knew the seller and put me in touch with her to get the ball rolling (lucky).

.- Seller Financing: It's an awesome way to create monthly cash flow and add financial stability to your operation, but once you decide to get into this realm, you'll have to learn quite a bit about documentation, how the laws work in your state when (not if) people stop paying, how to manage loans and collect payments (among other things).

This will help determine demand and where the growth is- Traffic counts- Tenant\Landlord laws. 

The person who can go see the property and meet/greet the seller/buyer.

It's not as easy as the sellers say it is. 

Hello Everyone,I have some motivated sellers and I'm trying to structure the Option to Purchase contract but after doing the numbers using the Wholesaler calculator available on here.

Wholesalers have no shortage of buyers, it is sellers that are the problem thus they don't typically look for buyers in the forums, you might have better luck reaching out to them directly.

Sometimes there just aren't enough sellers or not enough sellers who want to sell at a discounted price.

Even if not, I'm considering selling the house to them via seller financing.
