From charging a flare fee then transaction fees for every check, wire transfer, annual tax reporting etc.

Just for kicks, i looked up a few sf properties sold last year and see that land ranged from 40% to 60% so without knowing your property specifics, dunno why your land would be assessed 70%all i can suggest is look at comparable sales and see what the ratio is and then appeal using that dataalso i remember many years ago, a home was assessed higher than the transaction amount and after failing to reach agreement with assessor office, the homeowner reached out to the different elected city reps.

It depends on what the sale documents say and how the transaction was made, but generally speaking, you have no privity with the original seller.

It is good practice to obtain the L&I affidavit of continuous use from the seller as this can sometimes improve the chances of securing the rental license even if more than 3 years has lapsed.To demonstrate the uncertainty of L&I when rental licenses have lapsed for more than 3 consecutive years I will share a recent transaction of mine. 

This would be my first real estate transaction. 

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.

However, we found we couldn't keep doing that because some people would have 300 transactions per month (how on a rental?)

How did the transactions go?

Some have quotas, some don't.Like anything in real estate the gatekeepers of the knowledge are the people in the market on a daily basis.

., I will show the the physical location , concrete structure we do, money spend on HUB , money Made on HUB (next time ask to show HUBS those are public records and will not interact with the law) We have a book with all deals made in the community ... and you check, verify every single transaction!
