However, you can't sell something unstable, with circular references, requiring human override, etc.But, if you stabilized it, the model loses efficiency. 

@Phil SheltonYou would need a civil engineer to provide a drawing to get submitted to zoning and get a permit if it passes zoning is most common This also depends on the road - if it’s a state road forget it as it will take a year to get approved and cost a fortune - if it’s a local road process not as cumbersome but don’t expect this to happen quicklyIn some instances you may have to prepare sight distances etc to make sure it’s safe to add a curb cut

This also protects my downside risk because I could very easily lower my rents if I had to in a market downturn and compete vs. being forced to sell because of losing money. 

Will it be declared a super-sight?

You have to prove you did everything right and then because of “empathy” for the poor snook who “fell into you schemes” you may lose anyway.This is a legally binding transaction that will be treated that way by the law.

Not to mention short sighted as you are now finding out.

Let’s say with your plan they make an extra $100 or $200 in fees and you lose $1000 or $2,000 in bookings.

If you have high W2 income, the amount your STR makes (or loses) will be peanuts compared to the tax savings.

Stay in and be part of this 721 or lose my investment most likely.

You lose all of the control and these are long term investments - but in my experience the returns match what I had on the active real estate and I am hiring professionals to manage the assets.
