I am betting your gonna find a lot more friendly amicable persons than shut doors. 

Good morning @Cosmo DePintoHuntsville is an exceptional market where I’ve personally seen investors’ portfolios thrive.

Whether the seller was open to a buyer commission or not, I wouldn't put an additional cost into any personal purchase.  

Could it be considered piercing the corporate veil if the mortgage for the property is in your personal name but the deed is in the name of the LLC? 

That could work if you find the right person.

@Matt Solis would be the perfect person to speak to about this!

A relative who does long-distance real estate investing told me that I have to sign the final loan document and the transfer of ownership document in person.

I have sold some properties years ago on lease options where the tenant buyers actually exercise their right and purchased the property. ( I was in the deed.)The reason I am concerned to tie another person’s property up  with the lease option is that people can change their mind, as in the seller.  

I'd personally recommend @Andrew Freed.

Shadow/mentor a person doing it.
