You can get unpermitted work for much cheaper through specialty subcontractors that are unlicensed (usually because of immigration status).  

It still cost around $100K, but that is way cheaper than building a 2 bedroom ADU from scratch.

If you give me a loan at 0% interest, then everything up to the Applicable Federal Rate (AFR) is considered a taxable gift.

Personally, I invest in Worcester however in Fitchburg, you can get cheaper properties for similar rents hence the numbers do make sense. 

Hey John, To break it down for you: Capital Gains Calculation:For the 33.33% Interest Acquired via Quit Claim Deed (November 7, 2015): This portion of the gain would be calculated as the difference between 33.33% of the sale price and the original purchase price of $52,700.For the 16.66% Remainder Interest Acquired on November 17, 2020: This portion of the gain would be calculated as the difference between 16.66% of the sale price and the fair market value of the property on November 17, 2020 (the date of Person A's death).For the 50% Remainder Interest Acquired on January 17, 2023: This portion of the gain would be calculated as the difference between 50% of the sale price and the fair market value of the property on January 17, 2023 (the date of Person B's death).Consideration of Home Sale Costs: Deducting allowable costs associated with the sale (closing costs, repairs, etc.) from the total gain to arrive at the taxable capital gains amount.1031 Exchange as a Means to Defer Capital Gains: You're correct that a 1031 exchange could be utilized to defer the capital gains taxes.

Side-question: anyone have cheaper alternatives to Proper insurance for MA?

It is a lot of money, but cheaper in the long run, as it can take months or even years to evict a tenant.Unless my client had experience in this, I would never advise a client to think they can pull this off. 

I'm interested in reading it, obviously, but are there cheaper alternatives that have the same content?

According to my calculations, using Brooklyn's property tax rate of 0.78%, the tax should be around $354 per month based on taxable value of the property, not the $716 estimated by the agent.

My thought is that it's better to own fewer high quality properties than lots of cheaper ones.
