Call there bank and references or is there an official way to check there credit or is just the letter enough? 

Account Closed   Splitting the loan and  making a  SFR into a formal / official Duplex  is  complicated / costly  in most  cases ......getting  roomates to  help with income will be  easier and your best bet  ..... fyi -  you  wont be  able to  use this roomate income to  qualify in the  future ..... if you buy a  SFR to begin with -  consider using a conventional loan  so that  you can  use  a  FHA loan for  your  future MF  purchase 

Then you can officially reject that noise

I am excited to officially start learning and working in the field.

I got an agent to send an official offer and he has asked that I get the prequal done- So I am doing that now- I have looked at it and everyway I run the numbers it cash flows great and the CoC starts at 34% at 20% down payment.

The title company should be willing to take anything official - like the document from the bank.  

So I wanted to officially introduce myself, say hi to as many of you fine humans as possible, and raise a virtual glass to everyone I'll connect with along the way. 

Perhaps start with a conversation, but things like this should always be followed up with an official letter.

The buyers lender actually wrote up the contract on the official MAR contract.

However, we agreed that I sell my share of the company to him (and he will transfer the agreed-upon amount of my investment and profit to me).the goal is he will be the only owner of the LLC (and the property...).The question is- what the official, legal procedure for this would be?
