You cannot simply close with buyer (like all gurus say) then turn around and pay seller then transfer title to buyer- That is ILEGAL A way around this in case you cannot get transactional funding - Have your closing attorney draw up a Promissory not in submission to the buyer in which you will secure your equitable interest within the contract to the buyer...

The key is constant knowledge transfer and training so that you don't have all the domain knowledge in one person. 

or...are you planning on "helping them" (adding/transferring title into your name)?

The ACH transfers are slow but reliable.Cash: dangerous to handle that much cash, easy to lose, have stolenChecks: bounced check fees are a painPaypal and some other services: I have heard horror stories of accounts being frozen for weird reasons

Have done any soil testing or build studies so that you can transfer the land in a more opportune way than when you bought it? 

If not, you could take title as an individual and later transfer to an LLC (you might trigger some due on sale and/or transfer tax, so get legal representation on that).If LLC is not possible, I've used Revocable Living Trusts many times. 

With an irrevocable trust, for instance, the property is considered outside of the personal estate of the grantor, which can lead to different tax treatments compared to a revocable trust where the grantor maintains control over the assets.When it comes to capital gains tax, it's not just about whether the property is in a trust but also about how long the property was held, the basis at the time of transfer into the trust, and the selling price.

Looking forward to transferring those skills in to property management. 

I would like to transfer this property from my personal name to my LLC. 

this is done when your accountant files the form 8824 which transfers the basis of the old property into the new property.
