@James Baker I agree with @John Underwood, however I also understand the concern that maybe the previous landlord didn't keep to the standards you want when placing the tenant.

I recently was approached by a company who wants to buyout my rooftop cell tower lease. After getting approached by 1 company I reached out to a couple others to see what the lease was valued at for other offers. I am...

Doubt you'd have trouble with the appraiser or bank--your main concern, which is already clear from your post, is if/when the municipality uncovers the dark secret hiding in your basement.  

Concerns?

However, now that I see that the HOA is the one with most of the “for sale” lots, I’m concerned that they may be setting the “market value” and propping it up and/or they have too much control on what the market value is since they have such a market share.

I'd be more concerned about the liability aspect than the funding.

My understanding is that if tongue and axles are removed, home is strapped down, intended to be a permanent fixture, and title is surrendered to the state, I can request reclassification.

Feel free to reach out if you have any questions, thoughts, concerns etc.

If this is permanent "I'm never going to sell or refinance" financing, you will come out behind. 

I would get it checked out every few years, if you are concerned.
