The money that sellers are asking for town homes and -4 plexes are stupid high right now. 

When you submit your offer, make sure you have a due diligence period that gives you enough time to do these inspections.Once you get the property under contract, have the septic company do their inspection, have an engineer visit if necessary and get your property inspector out to do a full property inspection -- if he is concerned about a major plumbing issue or mold issue, you can get those specialty trades out to take a look and give you an estimate.If it turns out there is a bunch of extra work in these areas (or ANY areas) that you didn't expect, you go back to the seller and basically say, "Hey, there were hidden defects that I needed to bring in specialty contractors to evaluate, and here are the reports they provided. 

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.
