From that point on, he has earned bonus income.

It would be a bonus if it also logged gate activity.  

I have the opportunity to sell it using seller financing, but I'm trying to figure out how I will be taxed and whether bonus depreciation on another property I will receive for 2022 will offset at least part of it.

I would only count appreciation as a bonus and not core strategy.

When I sell the building my PMC has the opportunity to continue with the building if the new buyer wants which is just a bonus for them and they know I'm just going to go buy more for them to manage anyways. 

(global implications are a bonus).For background wife and I recently had our first child, so this has become very top of mind and in terms of assets we are in the Qualified Client+ territory, mostly in public investments (index funds, equities, public REITs, bonds, cash) with a little in private (real estate, crypto).Appreciate any good recommendations.

You can even add bonuses for completing ahead of schedule which is fair if you include penalties for tardiness.

A fourth bedroom and or and Office den would be a bonus but not a necessity.  good schools strongly preferred, at least elementary.

So you get cash flow while you own the property and a bonus when you sell from the property appreciation.

As a bonus, offer the owner a certain amount of cash (i.e 5, 10, or 20K).
