First off why am I up so late- This is crap:)
Sorry- Right you can not assign an REO contract, banks dont like it.... There are ways around this like assigning an LLC instead, but I'll focus on the best way to do it a little later...
Second you can not make offers on REOs without POF.... Its going to be required, so you will have to find someone who will back you, a HML, or a transactional funder to give you one....
Okay, here it is- You get a contract accepted from the bank. You find a buyer who is going to pay you more than you put it under contract for.
You tell you end buyer- Look I'm a wholesaler and that means we will be using your funds to close this deal. Now most will be fine with it because they just want a good deal.
Next the bank is going to say you HAVE to use our title company to close.. Well there title company will most likely not allow you to double close this, so you call the banks title company and say- Listen up- we are doing this my way or deals off! Just kidding, you will say look I need to do a courtesy closing, when the closing docs are done please send them to XYZ (your title company) Sometimes the title company will say no, at least this has happened to me, so you just say listen I'm the buyer and its my right to close where I want (not really true unless your getting a loan, but it worked for me).. Usually the banks will agree, sometimes they will want you to pay all the closing cost for the transaction.
But once you have that taken care of you and your buyer show up to close, they sign the paperwork, then you and your title agent meet with the Realtor, or not (most Realtors don't show up to closings), and you sign. The agent distributes the checks from the spread and you walk away with money!
So double close is what I like to do, some people use transactional funding to do it- but make sure your title rep understands everything. Some title companies will say, sure we can do that and then jack it all up, so use who other investors are using... Hoped this helped...
