We are just beginning the process of getting pre-qualified for a particular state and have had preliminary conversations with several potential lenders, both institutional and private, commercial, but we haven't yet submitted our documents to anyone. 

The vast majority of these folks want to kick the tires on the idea of investing or are just looking for preliminary information. 

The remaining 82 acres could fit about 200 building lots, per existing preliminary plans.

Bigger Pockets has state specific forums and I would wager that a local person in that forum would likely be able to have some recommendations for you. 

@Brian Wagers@Corbin Marcotte Corbin might have some insight or connections for you

I’ve also done some preliminary research in Wenatchee and just bought a house near Stevens Pass(in Skykomish). 

The preliminary title report has 15 items.  

His preliminary research suggests that we would likely be able to get approval for 4-6 townhouses on the vacant land and will probably subdivide it from the existing 2-family.

Once the money comes in are you also supposed to tag that portion of the income to the underlying category "Vacancy" and/or "Maintenance" so that you know its reserved for those categories, OR are those numbers just used for a preliminary "Is this a good deal" check?

@Gard Van Antwerp  Any Title Company who is reputable will run a preliminary title report up front for free, providing there is a high likelyhood of you choosing them.
