I would start with the Fair Market Rents (FMR) in the county where the property is located and use that as a basis to negotiate from there.Thanks Jaycee, are to referring to the HUD website? 

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

The group now has 30 members with discussion around negligence, mishandling of funds, fraud, and residual damages.On 6/26 my attorney sent a demand letter to Jeff Swiecicki requesting immediate payment of the balance owed.As of 6/30 Jeff Swiecicki has refused to pay back rightfully owed funds and refers us back to his 6/4 email to wait 90 days.

Just a heads up for future reference.

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

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.

I was just referring people to them which has stopped.
