I recently listened to a podcast and a story of a guy who had success with this in only 2 years.

I recently learned that if you owner occupy a residence for part of the 5 previous years before sale, and you rent it for the remaining time, you can calculate the percentage of time the property was owner-occupied (and thus qualifies for the sec. 121 primary sales tax exemption of up to $250k for single filers) vs the time it was being rented (which qualifies for 1031 exchange) and claim both benefits. https://hcsequity.com/blog/combining-1031-exchange-with-121-....How does this work for a multi-family?

@Andre Jones Hey, feel free to DM me I'll share a few references, 

Does your time line line up with the deal you're investing in?  

The buyer requested a transfer from his job to the city where the house is but now the job wants him to start work next week, I told him we can probably let him and his family occupy the property prior to the closing date.  

I'm a financial planner who works with real estate investors - we have a client who plans to renovate a Clinton Hill (Brooklyn) property that has been in his family for generations into a multifamily rental.

You've already gone above and beyond, but it seems you just dig up more problems.When you run a credit/criminal background, the credit report should list the applicant's current and previous addresses.

The county tells me I could add up to 3 ADU's, one in the basement (at the same time as replacing the foundation) and two detached ADU's.Adding any number of ADU's has the potential to double my current cash flow.  

I've had properties listed for more than what section 8 wanted to pay, we had to provide comps that their estimate was wrong / out of date for similar apartments. 

You can also write off travel to and from the property and more.
