Based on your description you are referring to a "portfolio" style of loan or sometimes called "Commercial" loan.  

@Vic Wilson - it's a bit hard to understand your situation from the description you give.

I'm assuming this is a rental property and based on your description you likely would not be able to get "conventional" financing....meaning, "delayed financing" would not apply here.  

From time to time you'll find very descriptive listings, especially in the luxury markets.

The document also has a room by room general description of everything and a link to a google photo album with like 50+ pictures.

Slightly different scenario, as the bank mistakenly had the incorrect legal description on the original mortgage, released it from that property but did not properly re-record against the actual property. 

Does anyone have a recommendation for a CPA that they've worked with that fits my description above?

You'd want to ensure there is a separate mortgage with a complete legal description recorded for each property.   

Understand exactly what it is you're looking for and be able to convey to the brokers a detailed description of the type of property you are looking to purchase.

Always document, have them sign an addendum to the lease if it all possible with a very short description of mutual agreement termination (no need to be specific here, I would suggest just termination dates by mutual agreement... period).
