A bank can issue a loan specifically to "bridge" your down payment for your next property before you sell your own property. 

In one instance, the seller had very specific terms.

Are there platforms out there specifically getting investors matched on a per-deal basis?

What I am specifically looking for is perhaps a hard money lender that will work with my equity and not so much with my financials or credit history.

My guess is that this is a bank/CU specific loan program. 

As far as specific cities go... if you like it hot - Phoenix area or Lake Havasu City (LHC) may suit you.

I have an rta website that has much better quality than home depot and can come assembled to your jobsite.

The other question is, do I need specific verbiage to do the Quick Claim Deed for the series LLC?

Rather than go into all the specifics I would suggest you read some underwriting books to understand how to analyze these larger deals.A few that come to mind are:- Multifamily Millionaire Vol 1&2 (Bigger Pockets) Multifamily Millionaire Book Bundle – BiggerPockets Bookstore- Hands Off Investor by Brian Burke-  Definitive Guide to Underwriting Multfamily by Robert BeardsleyThere are many others out there, but I would suggest starting with those.

When you are using OPM I think you should always have a specific deal before you open an account or transfer any money.
