As already mentioned, you could sell via seller financing to lower AGI, as all you would have to claim is the payment income - until balloon payment received.Did know an investor that had 14 properties paid off and he moved into one every two years to then sell with the $250k single exemption.

My question again stems around using seller financing to allow them to receive a consistent monthly pay of X amount and delay/lower their tax bill in the short term instead of going through a lender to borrow 800k+ causing my mortgage to be significant part of our income roughly 40-50% of take home -  which we are approved for LOL.

This implies residential units can be built at lower costs and provide better return than building a single ADU.11) adding an ADU to SFH can make the SFH fall under rent control.

You are generally going to either buy it at 95% of value or what is owed, which ever is lower. 

This could lower your resale value. 

Lower than that?

Delta has not charged me extra for the new block.

For STR people we charge them 1.5 months rent and make them do all light maintenance 

Just this week, we've re-opened our search for a rock-star mobile app designer who will lead the charge from user experience perspective. 

The negatives are that rents are might be lower than market rates and definitely than Airbnb rentals.
