@Brittney Yang first red flag is it doesn’t sound like he’s that interested in long term holds but the primary reason for partnership is expertise in renovation and secondary reason is balance sheet and income to help get financing.Regarding reason one, I would offer to compensate him for his time in assisting you and have a very clear scope of what that responsibility is.  

When I started getting emails from other affiliates trying to get me to invest in additional resources, it sent up a red flag for me.

The inspector wanted me to add 2 screws to anchor the condenser and he did check for leaks at the gas connection (the gas connection that was flagged was decades old and I questioned if was before a permit was required but city stated it was up to me to prove that it was there prior to permit requirement).

They give no official closing documents, just internal documents that I'm guessing are fraudulent. 170% profit in two years is a HUGE red flag🤯 

Weeks later found another buyer, barely qualified, a pain to work with, does not respond half the time, red flags all over, seller is motivated.

I’m the last person who should complain about grammar, but these are yellow flags, at best.

There are carriers that will write landlord policies without a % deductible.

The 3 issues you described are all fairly large red flags, especially for someone's first property.

To me, this is a red flag.

In MN if you try to get a rental license and your nowhere to be found on record of ownership and there is a different owner on record, there gonna catch n flag that requiring the "actual" property owner has to complete all licensing requirements.
