First off, how do i get the seller to sign the contract, by sending it through email or a certain website?

@Mica MooreThe answer is "it depends" no one on the forum has enough info to give you specific advice.  

I would recommend consulting with your insurance and then getting your lawyer to draft one specific for your property.  

There are strict rules regarding this when using retirement funds.I found a great website showing the advantages of rolling 401k money into a self-directed IRA.

@Jason Yang do you have any specific questions or did you just need a referral? 

Specifically, these properties were in Stone county. 

I find that I can take care of most things inside of Baselane, and initiate transfers into and out of using the Baselane website. 

It's crucial to understand the state-specific regulations regarding like-kind exchanges, as some states may not recognize or fully conform to the federal provisions.

You can find some on the Neighborhood Building Owner's Alliance website. 

I don't lend in NY (we do investor loans in most of the country and consumer loans only in FL, but we do nothing in NY), so I don't have a dog in the hunt here, but don't discount other types of loans, including a loan designed specifically for flipping.
