The quotes I am getting are very high .

With interest rate so high - 7.2% in my case.

We only carry E.I. on our primary residence, not our rentals, and am considering dropping it altogether because the deductible is so high.

@Carolyn McBride this is HIGHLY dependent on where you are in the country. 

Third, I would not pursue the ADU route if you have a high income and demanding W2.

Highly recommend getting additional inspections (termite/mold/foundation/roof) if needed to assess the condition. 

Most of the houses are highly priced.

High income earners may be subject to an additional 3.8% tax called the net investment income tax on both short-and-long term capital gains.So, yes, if your only objective to avoid capital gain and pocket the profit (not to do 1031 exchange or QOZfund), then stretching it to 2 years is your best option.

The GP share of the profit at the END of the deal also know as the PROMOTE is generally 20% to 30% of the profit (big picture high level). 

I would love to know this too as I am looking for a mastermind group to join and help with knowledge sharing, learning, skill development, conacts/networking, accountability and of course fun...which is highly underrated.
