I have talked to a lender and gotten pre-approved, but plan on meeting with a few others as well as some real estate agents.

You're right, between getting pre-approved to starting the search, viewing many properties, making offers, getting offers rejected, finally getting one accepted, then having it fall through (after the inspection, for example), then going back to looking at properties, finally getting an offer to stick and taking it to closing (which could take 45 days or longer), then doing the rehab -- it could take a while! 

I assume so...if this is the case -  conventional  financing should be available for each property ( not as  one  8 unit loan )  ...would you  live in any of he units or rent them all ....down payment required is  substantial ...if engaging seller on their  financing  terms  - ask  what  amount down is  needed ( it will likely be large )  length or the  term and the rate / payment requirements ...if you cant obtain  traditional financing - seller financing is an option ....if engaging on  making any offers - make sure you are  fully  pre approved  with a lender ( if you need a loan )

You really need to get pre-approved with a lender so you can map out your options.

I already know my agent will want to show POF with any offers and I could show a pre-approval letter from the hard money lender but I don't have a money partner yet to show proof of funds for the rest of it.

My Question is if courts approves and grants Her and Me as the New Partnership and puts title/Deeds in our names.

As such, assuming her broker is plugged into the situation and approves, you need to disclose to the seller what you are doing up-front, or most certainly at same time you submit your offer, so that the seller is fully apprised of your plan and can consider your solution before they accept.  

If the buyers are under the contingency time frame such as attorney approval, inspection, mortgage approval, etc that is there out.  

The reason is I know which lenders: do a good jobstay on top of the necessary tasksknow how to be creative within the rules (some people don't fit into the standard mold of a buyer, and some lenders don't know how to get them approved, and some lenders know how to get them approved)and which lenders can actually close deals.

I just able to get approval for commercial loan using my 2 year return from these companies I been building for 2 years now.
