Let's call them House A and House B for reference.

I require the medical provider to explicitly state they are aware of AB468 requirements.  

i wasn't in a position to buy it by then so i referred them to a friend of mine and he bought it. 

I learned to call others investors who referred me to trustworthy contractors.

If it's not included in the rent, many companies charge a flat fee to monitor & pay utilities.2) Assuming you're referring to resident benefit packages, renters insurance, and other charges for services the PMC offers to tenants. 

I have a written office policy manual that explicitly permits my employees and sales agents to carry at their discretion.

These are just a few basic things I'd look for.In reference to the agent, you definitely want to find the investor focused agents that does a lot of deals and lean on them for their expertise.

Wondering how to build trust in him to do seller financing with us after this.For reference we have 100% close rate, my thoughts approaching this is to counter back and say the risk of default is very rare, if he's worried about the park defaulting he just needs to save up $20k in reserves and he'll get paid $70k in income for the park for the next 5 years while he waits for balloon.

But I do refer any EMD request over to a contact of mine who happens to be one of those 20%. 

I do my own due diligence and call all reference numbers, past landlords, and do an in person interview.
