Here are the Fannie Mae guidelines for legally non-conforming properties:If the Property's characteristics are legally non-conforming, you must:ensure the Borrower executes the Modifications to Multifamily Loan and Security Agreement (Legal Non-Conforming Status) (Form 6275);confirm whether, if fully or partially destroyed, the Property's Improvements can be fully rebuilt to the pre-casualty condition per current laws, zoning requirements, and building codes; and if the Property’s Improvements cannot be fully rebuilt to the pre-casualty condition, evaluate if the as-rebuilt Property will support the Mortgage Loan at the current Tier, and document your analysis in the Transaction Approval Memo.To assess the Borrower's ability to rebuild Improvements on a non-conforming Property to a level that will support the Mortgage Loan at the current Tier, you should consider: conducting a threshold analysis to determine the resulting actual amortizing DSCR if the reconstructed Improvements cannot be rebuilt as-is per current law; the likelihood of a casualty event (e.g., wind, earthquake, fire, flood, mine subsidence, etc.); the percentage of damage to the Improvements at which the Property’s jurisdiction will require the Property be rebuilt to current zoning and land use requirements (i.e., the destruction threshold); which Property characteristics the destruction threshold percentage applies to, such as market value, assessed value, replacement cost, or unit count; for Properties with multiple buildings, if the destruction threshold percentage applies to each building, or all buildings as a whole; the replacement cost to rebuild per current requirements for zoning, and land use; the Property’s continued marketability, and economic viability; the amount and type of Borrower-maintained insurance coverage required per Part II, Chapter 5: Property and Liability Insurance, Section 501.02C: Ordinance or Law Insurance; insurance loss proceeds payout, compared to increased rebuilding costs, including from building code changes, Americans with Disabilities Act compliance, and the municipality's local zoning requirements (e.g., green compliance for new buildings, etc.); the sufficiency of estimated insurance proceeds from ordinance or law insurance and other coverages to repay the Mortgage Loan in the event of partial or full casualty, or condemnation; and for a Tier 3 or Tier 4 Mortgage Loan, if requiring execution of the Limited Payment Guaranty (Form 6020.LPG) would mitigate the risk of the as-rebuilt Property not supporting a Tier 2 Mortgage Loan.

It might be a good idea to discuss your specific goals with a few more lenders from the approved list to see if they can work within your parameters.

I own a small lot in Sutherlin (between Danville and South Boston) with a mobile home on it, I would like to rent this place out if I can. 

Also, by risk I mean its your time and you have to get their approval or you wasted $800.

The other issue is most banks/lenders do not allow the owner to do their own work or act as a GC unless they are licensed as a GC and approved with the bank/lender.

Landlord has approved. 

I'm currently in the process of getting approved for a $160,000 HELOC on my primary home.

For this house as it is relatively close to other homes we try to get no dogs and meet/approve any dogs if the tenants are good candidates most people don't have time for that.  

Park Makeup 3 TOHs, 6 POHs(Ones a Doublewide if that matters), and One Empty pad that I could use for projections for DSCR according to one commercial lender.Is there any way to better gauge what a park might appraise for if looked at for only pad rents occupied by mobile homes?

I've always seen a disclosure in rental lease by property management saying "This lease form has not been approved by the Colorado Real Estate Commission.
