This year, when I listed it for sale, it got multiple offers, and we set a new record high price of $705,000 for ~800 sf.

If you went directly to the agent listing the property then ask them, and if not then ask the agent that represented you for the sale to get you the contacts for it. 

And you can go into contract for your new property at any time you want - even before the sale of your old property has happened.

My firm has a fix to rent product that discounts the interest on the fix portion, and discounts origination on the DSCR portion. 

What I did was after my sale was under contract and I was down to a couple weeks from closing I started shopping seriously and had my replacement under contract a couple days before my sale closed.

Both of the books are available in audio, physical book, or kindle format and are on sale for Black Friday right now at the amazon links I listed above!!

My loan officer seems to believe this means that I need two separate loans, sales agreements etc... 

On the other property seller adjusted sale price.

If the house is done NOPE just customary for our market which is 5 to 10k what we focus on is how much downpayment and lender they are using.. a good portion of our sales are all cash so that removes that uncertainty..

Maybe something happens on the block which pushes rental rates down, but still provides a sale option.
