I spend all day every day underwriting proposed commercial loans and analyzing the risks associated with them.

I think that this is absolutely where the market is headed and am certain that the way my children purchase real estate is going to look much more like the model that he proposes than the current status quo.

It is behind a paywall, but the story basically goes:"A Lucas County judge granted a preliminary injunction Friday [31 March] to stop Toledo’s lead-safe certification rental law from going into effect on the day the new lead ordinance was scheduled to be enforced.Lucas County Common Pleas Judge Gary Cook ruled on the injunction Friday in a lawsuit filed by Toledo landlord and rental manager Charmarlyn Strong who is challenging the city’s lead ordinance.The city of Toledo has “passed, rescinded, and passed again multiple versions” of the ordinance, which has created a ”somewhat convoluted set of circumstances for the court,” he wrote.However, the injunction is not necessarily “a decision on the ultimate enforceability” of the proposed ordinance, the judge wrote.The next hearing on the case is scheduled for April 27.For now, the lead ordinance remains “status quo” until the judge can review all of the legal matters, city law director Dale Emch said Saturday.

Obviously, you're looking outside of cities, but for instance, Colorado Springs' proposed new Airbnb ordinance would prohibit airstreams from being used for Airbnb.

Additionally, you could have a conversation with your buying agent to get their feedback on the proposed incentive plan and whether they think it's reasonable.Remember that building a good relationship with your buying agent is important, and being transparent and open about your financial limitations can help build trust and foster a positive working relationship.Overall, offering incentives can be a powerful tool for building a strong team and achieving success in real estate investing.

The process I propose is illustrated below.

This proposal has further process to become law, but it seems likely.  

I will clarify with him the full amount that he's willing to place in the transaction and then propose a percentage of profit and cash flow that works for the both of us.
