I personally know half a dozen people running dispensaries and leasing land to growers. 

I could be very wrong about this as I am just learning about REI but I'm wondering about the assessed value of the property.... if the assessed value is high enough (I believe LTV of 80%) couldn't this be refinanced to pay off the loans and turned into a conventional loan?

I run my own comps and also assess the repairs needed.

The rent application would include all information required for a lender to assess whether the renter would qualify for a mortgage (e.g. 2 years of steady employment, tax returns, no bankruptcies or outstanding judgments, etc.).

I've also got one property where I have talked to over a dozen lenders and I'm still debt shopping. - Find a mortgage broker and they will check with a bunch of different lenders.

Does this cause anyone to revise their assessment of where the real estate market may be headed next year?

I have note run into this personally, but a local landlord who owned about a dozen places and has now sold them ALL with Seller Financing (one or two per year) set his 'down payment price' AFTER talking to his Accountant/Tax Guy.

Also dig into the condo docs as sometimes there are special assessments that can come up from time to time beyond the regular condo dues.  

I've probably dealt with over a dozen incarcerated individuals and once I stated I'll put money in their commissary, they reply with "When can I sign?".

Then, once the wholesaler receives the seller contract, he or another person will take a look at the house, assess repair costs, run comps, determine ARV, and therefore the negotiation can be based on the actual condition of the home without any risk of losing the assignment.
