No, the purchase agreement doesn’t need to be notarized – however, in some states (like Michigan, for instance), you technically need to get a witness signature to go along with each party’s signature (the witness doesn’t need to be a notary, it can be pretty much anyone). That being said – there’s nothing “wrong” with getting a notary’s signature on this, it’s just overkill.
With this in mind, I spent several months putting together a full-blown course that explains how this process works from start-to-finish. The course is designed specifically for people working in the land investing business, and it comes with dozens of video tutorials and document templates that give an in-depth explanation of each step along the way.
Hi Walt – certainly. The delinquent tax list could be a solid way to get started. I typically look for land deals when I’m wholesaling, whereas most wholesalers are doing land… so that would be one key difference in the types of deals I look for (mainly because land is a much simpler type of property to work with – even though there may be fewer buyers for this type of property).

Depending on the property, you may even find that closing the transaction yourself can be faster and less cumbersome for everyone involved. If for no other reason – I've found that it's extremely helpful to have a basic working knowledge of how real estate transactions actually work. It's important to understand why title companies require what they do in a closing, which documents are an absolute must, and which documents are more discretionary in nature.

You may want to add an ‘escape’ clause, which allows you to keep the house on the market while the buyer sorts out the conditions of purchase (e.g. arranging finance, getting a builder’s report). If you receive another offer during this time, the clause gives the buyer a set number of days in which to go unconditional, and if they don’t you would be free to take up the other buyer’s offer instead.                    

It depends on a number of factors, are you trying to find cash buyers for your land, what is your time frame to sell the land, and are you trying to get full market value for the property, and how much work do you want to do to sell it? Depending on your answer to those questions the method by which you decide to list and market the property is going to be different.
